Wow was lookin though hot rod and saw an ad for a "350 tbi engine" and went to the site they have quite a few good engines but check it out man it looks like a l05 long block they have a 210hp longblock and a 270hp longblock. i would go for the 270 and for 2150 what a snag! Anywho the link is http://www.goautocenter.com/350_tbi_1987-9.htm what do yall think?

 

Thats actaully not a very good deal you can get the gmpp 330 hp 350 for $2200. Or you can get the Goodwrench 250 with 260 hp for $1299. So I wouldnt get either one of those tbi engines. If your going to get a new engine you might aswell get a performence one not a stock replacement. Good Luck.

 

the gmpp is not 2200? where is that! i need one! on summit its like 3k well thats with a turn key i thought the long blcok was 2500.

 

I would not spend that much for a long block. You can get a new LO5 or L98 shortblock for half of that and then pick up some performance heads of your choice on top of that. You should be able to come out cheaper with better stuff.

 

went on jegs and put together an engine combo and the gmpp motor with intake and exaust is like $3638.94 isnt that a little steep? i meani wolnt beable to buy nice tires a torque converter or rear gaers for quite some time so with this big motor ill be running a little faster than stock for 3000 bucks i find this a little odd what times wouldi run with that engine a holly 670 holy intake and hooker long tbues out 3" flowmasters? i would need a new chip which my friend can tune for me and thats no ploblem so what do you think it will ru nwith that and its properly tuned i hope atleast a mid 14! thansk for the help i thought it was a snag put pops said otherwise *edit* wowowowowowo this thing is votec i dont think im spending 350 bucks on a dang intake! that will rise that price 150 mabey more dollors im already on a tight budget i cant aford vortec stuf shift where can i get a l05 engine long block turnkey short block anything where could i find one and what kinda prices am i looking at

 

Jegs has the 350 ho longblock for $2200, get a performer vortec CARB MANIFOLD NOT TBI and use a tbi adapter plate from turbo city or wherever else makes one, then get the holley 670 and a chip and youve got all you need. With a properly tuned chip you should knock down high 13's with decent gears. Also you dont NEED gears or a stall for that motor. I would defetely recommend at least 3.42 gears and you should knock down high 13's all day.Oh also if you dont have headers and a 3'' exhaust youll need that too. Oh and shiftys idea is good to.

 

Check out the L98, L31, or zz4 lonblocks from here. They are as low as $1500 IIRC.

Hey, this is for anyone interested in putting a freshly rebuilt 350 in their car. I found this site and they're the ones I'm going through to get my V8.

http://www.chevy-350-engines.com/che...html?catid=111

check it out and tell me what you think.

 

Those aren't to bad. You will find that most new production shortblocks will cost about the same when it is all said and done.

 

That's the place I'm getting my motor from, but I'm going w/ the 350 TPI motor, because they offer the CompuCam 2030, and Trick Flow heads for 2855 installed.

Rich92RS350 went w/ the TPI motor w/ the CompuCam and he put up 320 HP and 399 lb/ft @ the flywheel. I'm hoping with the Trick Flow heads and 1.6 RR's, I'll be over the 350 HP mark, which I don't believe should be a problem with those heads.

In short, I think they're underrating their motors.

 

Cool beans i just found out i dont need to spend any money! my pops said if i want a block i shoulda asked him hes got 2 283s a 327 and a 350 (4 bolt mains). the 327 and the 350 ar both from trucks (full engines) and the 283s are just blocks. hes also got lots of goodies lots of random engine parts and 2 trannys (powerglide *ooooooo ahhhhh* and a 4 speed manual) i just now gota descide what i want a 327 or a 350 he said the 327 is a badass little motor if we finish it right he said he had it goin 100 in second gear lol and hes had it up to 10,000rpm. what im thinkin is we clean the eignes get the heads redone and jut take the carb off get the tbi adapter plate and put on a 454 or 670 tbi with bigger injectors. im kinda leanen twards the 327 just cuase it can be a great street strip motor and still get my on the gas and plus its different you never see a badass 327 thirdgen hell you dont see alot of teal thirdgens with a black stripe! i want it to be a car you'll rember getin wooped by. any input would be great!

 

Well the 327 will be different alright, but I don't know about building one up when the 350 is so much easier. Nobody at a red light is going to know if you have a 327 or a 350. You might as well go all the way. Don't forget that tuning your computer to work w/ a 327 is not going to be near as easy as the 350 as well. There's a lot more to it than throwing an adapter plate on a carb motor and hauling ***. Computers can be finicky.

 

In what sence would the computer tuneing be harder? i really dont understand that and where might i find elp on computer tuneing i have a freind (manager of mufflex) hes told me he could help tune the car to its max specs (hes had over 20 years with cars mabey more) so with the help of a ase tech and some will powers could it be done not as hard as its made out to be plus a 327 is just so cool! i mean everyone nad his grandpa has a 350 a 327 is cool and different and its alot strong than the 350 so why is is so muh harder to tune i mean a 327 is a 350 with a smaller stroke its alot easyer than a 305! i mena a 327 i can buy pretty much everything for a 305 is quite another story.

 

I think you meant shorter stroke not smaller bore, didn't you?

Steve

 

yes indeed i should edit that. and i think the shorter stroke is a plus i can rev that engine up to very high rpms becuase of it and plus a 327s a stout little engine up to 400hp which i dont think ill be comeing close too im gonig for more like 350 - 370 rwhp range

 

I would only go with a 327 if you are going carb. It is much easier to have FI friendly 305 or 350 with TBI, that is if you want this to be TBI.

 

i dont understand how it would be harder? can you guys go into a little more detail please. i mean whats the difference between the 350 tbiand the 327tbi?

 

What's the purpose in revving to 10k RPM? What cams are you going to get that will have a powerband anywhere near 10k RPM?

Also, quite the contrary for parts. You say you can get 327 parts all over and no 305 parts... I see 305 parts more often than I see 327 parts in magazines/catalogs. The 350s aftermarket seems to dwarf either the 305 or 327 though. The more rare the engine (or in your terms "bad ***") the harder it'll be to find parts, no? :-/

 

Well i dont have any explanation why i would waan do that but i can plsu is a 67 corvette motor which means 350hp 360 footpounds of torque which is awesome. and yes thes specs are correct cuase only one 327 vette engine was offered in 67 and thats it in a 1967 Chevy Shortbed stepside. and i feel that 350hpand 360 torque arnt to shabby for me in my eyes thats the perfect motor! its got the hp and torque i want in a nice size plus its unique and cool with a good drvieline i could lay down some tire shreddin power... and yes thatis badass and you'll never find a set of 305 pistons in the big catologs like summit and jegs and they are very low compresion pistons when you do find them. so the aftermarket for vette engines is quite large sir.

 

Okay, so I lied. There are a lot of 305 parts, just not a lot of 305 pistons, and the ones that are there are for low-compression, you got me. However, there are probably 2-3x as many listings for 350 parts as there are for 327 parts. Why not just get the 350 and turn it into a 383? That's what I'd do

 

Yeah i hadthat ideafor awhile but it would just cost more and its just not like me to have a engien that million of other gearheads do i mean if i was like that why didnt i jsut get a 4th gen? thats why i got a third gen i feel thats these camaros and firebirds are gms last volley of muscle car spin offs shure they arnt muscle cars but they damn shure look it and are it like a 4th gens isnt a muscke car in my mind it looks like a sport compact on steroids.. i mena muscle cars didnt have luxry features like leather seats or power everything yeah this has some power but look at it its the bare minum gm had to off in sports cars and im kinda proud of that plus theres not so many tweeked with thirdgens down here but there are tons and tons of hooked up latemodels and plus whenyou pop the hood at the local hang out its mind baffleing to a ls1 when they just got smoked by a 1) Thirdgen 2) a 327. it would jsut blow there minds what i can do for alot less than them think this way the car cost $3000 i take the 327 out and rebuildthe eigne clean it get it worknig right againthat cant be more than 500 to 1000 bucks and look you got bet by a car that the person payed 50% less for. i dont know i think im a little bent on this 327 its too bad my dad gave the th-350 that was inthere he has a vega converter he can give us though lol 3000 stall.

 

Please keep this TBI related. A 327 is a non roller set-up. By the time you put the money into it to make every component TBI friendly you could have a 350 that will meet all of that and be much cheaper. You can make any small block TBI, it is just if it is worth it or not.

 

OK So far ive planed on geting a carb-tbi adapter plate, holley 670tb or 454tb , and ill get misc things airfilter oil filter plus wires distrib cap and engine cleaneing products the eingines comeing apart being cleaned and put back to its orignal glory what else might i need? oh yes and as an aftermarket upgrade ill be adding a 3' exaust system feed by hookerlong tubes which i guesstamate to be about 1-2 dollars in total. afteri save somemorei plan on a alum driveshaft,psi traction and some drag radials or some mickey tompsons. i feel this is a powerful set up and if i get the computer tuneing right tis 350hp and 360 foot pounds of torque will put me right in the 13 range i shure as hell know its not gona run a 14... i guess i should start practiceing my computer tuneing on this stock 305. oh btw do i have to build my own connector cable it wolnt be a problem just gota know the cost ect thanks forthe help so far but i have descided this 327 is treuly cool!

 

what does it being roller have to do with tbi? please explain

 

Most non roller set-ups do not have cams that are EFI friendly. meaning they do not have the nescessary cam specs that FI systems need. Since a 327 has always been a carb motor I assume the one you have is set-up that way. The only non roller FI set-ups you'll find out there are late 80's and early 90's truck V8's. So, you would have to make that 327 a roller motor, which will cost you $$. You will also have to decide which vavle train set-up you want, non-self allinging vs self allinging.

 

so what your saying is its jsut better to stick with carb? what means no comouter but then i would have to get a non computercontroled trany and the gas will cripple me how might you know its not a efi friendly cam ?

 

What I am saying is stick with a motor that can handle a TBI system. A cam that is FI friendly on stock GEN I heads has less than .480" max lift and 112 or higher LSA. Besides a few truck motors you will find that most carb set-ups do not meet these specs.

 

well i asked pop he said he bought it fro ma guy and the guy said its fro ma 67 vette and its a mix up there it can be the 350hp option or the 300hp base i have the camspecs for both... 300hp first: Intake and exaust duration: 300 intake and exaust lift .398 . now for the 350hp: intake and exaust duration 342 intake and exaust lift .447.. both are within thoes lifts you posted seems liek ti wolt be much of a problem eh? *edit* and yes the intake and exaust is @.050 and these specs are from chevy

 

What is the LSA on that cam. I would put my life savings on it that it is less than 110.

 

lsa? what exactly is that

 

Well i have descided the tbi would be kinda a hasle why not tpi Third Gen Resource with the wireing and computer and stuf for 600 what do you guys think?

 

Because TPI isn't that great. You can make much more power up top with your TBI than any stock TPI set-up.

 

Use the 327 just get an aftermarket flat tappet cam that'd be computer friendly, there are many out there for pretty cheap. Keep your TBI setup, TPI is a waste of money on a 300+hp engine if its in stock form.

Also, you mentioned earlier about your transmission being computer controlled but it in fact is not computer controlled just a FYI.

That could be a good engine combo, just look into chip tuning and a Holley 670 TBI unit.

 

THanks for the suport Bron the first person who has. anywho your all right i could find a nice flat tappet cam ,addapter plate and a 670tbi im gona build the motor on a stand (why wouldnyt i) and then drop it in. what tools will amke it easy for computer tunenig id like to get perpared and try it on tihs 305. And i cant thank you enuf for all the help youve given me so far shifty..

 

Check this Out

 

*Print* thank you very much. ive guesstamated this project to be around 1-2k worth of rebuilt and aftermarket parts this will be a fun journey. and once i get the engine down from up north i will be shure to start a progress thred with pictures and all i guess i can say its time to start project tbi 327. with what bron said about getin a nicer cam it should start serachin and my frist though was duh lt1 cam. that would meet the specs you listed right shifty? plus since its rated at 300hp and 360 foot pounds of torque what kinda power could i expect with all the stock componets a lt1 cam and holley 670tb? the engine will be rebuilt with new cap, plugs, wires the usual stuf. i am assumeing i will be at or above the stock rateing with the right chip tuneing. Well wish me luck and i will be casting off ill get my 327 build thred up once i go get the engine (2 hour drive) and bring it down tear it down and clean it order my parts ect...

 

Isn't the LT1 cam a roller cam? Look for a flat tappet cam with an LSA of between 112 and 116, as Shifty said. It does sound like a cool project to me if ya have the money and can find the parts

 

The LT1 cam is a roller cam and will work in roller blocks only. For that 327 you are going to have to find similar cam specs but for a flat tappet cam. You can go the non roller route with the 327 it may just be easier to do it another way. Never the less if you find a good flat tappet cam that will work with TBI you will be off to a good start.

 

Thanks.. Yeah before i went to sleep andi thought about it and i remberd it was roller cam. ahhh more hours of reading and find a flat tappet cam of chice. thanks alot guys im glad for what a response this has generated.

 

I was just looking in one of my Summit magazines (its from a few months ago, but hte part numbers should still match up), and you have a afew choices.

They have 9 available with a 112* or 114* LSA and varying amounts of durations and lifts. Part numbers are SUM-K1101 to SUM-K1109. Varying durations from 194*/204* with .398"/.420" all the way up to 254*/264* with .533"/.555".

I'll keep looking through this magazine, but that's what I've found so far... I'll check on Summit's site in a few minutes to see if I can't pull up a webpage with these on it as well.

Also, these cam kits are all pretty cheap, at $80 a piece no matter which one you choose. They include the cam, lifters, and assembly lube.

 

Just pop in any of those part numbers at www.summitracing.com and you should get some info on them. Take note that the SUM-K1100 will NOT work because the lobe separation is only 109*

 

You could use a LSA of 109 but you would have a lot of lope at idle. This may be hard to tune around. I have yet so see a tuner use anything lower than 111 for a TBI set-up.

 

Well yeah, which I didn't think he'd like...unless of course he wants a really lopey-sounding idle. Might sound kinda scary

 

THanks you two. Thoes prices i cant beat but i want it to somethingi can trust in a daily driver. Thinking aobut it i think they look like nie cams and plus when buying brandnames (Crane,Comp,Lunati Ect...) all your buying is a product name and a cam probly equal to the summit discount one lol plus lifters and lube cant beat it. i think this tbi build up wil roll smoothly and great when its all said and done i hope to be produceing 300-350 rwhp i dont think it will be too hard since the whole engien is geting torn down andi have about a 2-3 thousand dollar budget i will be able to get all my rebuild and some go fast goodies. Thanks for the cams again i almost forgot summit almost always look on jegs cuase they have more tbi stuf. *edit* wheres the lift specs on thoes cams?

 

Not to be the thorn, but you are going to have a hard time getting 350 at the wheels with a 327 and TBI on top. I would shoot for 240 to 270.

 

guns are runnin 13's n/a with 305 tpis what makes you think a 327 tbi cant run a 13? i say if this thing has 300 at the fly from the factory in this f-body with a new cam nice aftermarket tb big 350 injectors and a costom prom it should have a had time makeing 300hp or more at the fly. with a saw 3275 car *with driver* it will run a soild 14 or 13 and with the posirear some good sticky tires and some tranny work it run a soild 13 right where i wana be.

 

Oh you should get the time you want but not the power levels. Your last post is right on though. Expect 300 at the fly and 13's with proper tuning. I thought you had your hopes up of 350 at the wheels which is over 400 at the crank.

 

I know i may seem anyoing at sometimes but a 16 year oldwith little neigne skill (i am takeing "practical engine mechanics" wherei learn the 4stoke theory and smok on small engines but we did tear down a 350 and rebuild it ) but i get my hompes high and 300 to 325 or mabey 330 at the fly isnt too hard and it will put me in the desired time range and it will get me atleast 25mpg tuned (hopefuly)

 

Now you are thinking straight. Good luck and make sure to post your progress.

 

I'm 16 years old too and I also have seemingly-unrealistic plans for my cars all the time, but now that I'm making some money, I think I'll be able to put some of my plans into motion...as soon as I get my '91 Firebird...gahh!! Oh, and I'm also doing what Shifty recommended. Build up the rest of the car (i.e. suspension, rear, exhaust, etc.) and then I'll be moving onto the engine. Hell, I already bought a 3" cat-back for it and I don't even have the car yet Hopefully by this weekend if I get rid of my car tomorrow night
