I just picked up a 1990 chevy 4x4 lifted with the 5speed and i am going to pull the motor out and put it in my camaro jsut to get it going. i am not going to use the tbi. just going to put a high rise intake and run it with my 650 dp. i am pretty sure it has the swirl ports. but it runs really good and has 60psi oil pressure at all times. and i can get rid of the v belt set up.

what is a good cam for this motor? i know with the tbi it can only be a 272 after that the tbi has problems with the tune.

as for the truck its getting caged and new tires for a prerunner build i have always wanted.

toolegit86

i do plan to put heads on this motor later... as for now do i have to run the vortec style intake?

No. The 1990 models were not "Vortec". The V8 Vortec debuted in 1996 in light trucks. You will need an '87-up intake bolt pattern.

The swirl port heads can't do much with more than .450" lift. So keep the cam fairly mild. Between the swirl ports, Performer-type intake (idle-5500), and a mild cam, you can have a very torquey, well-mannered and reasonably economical set-up.

toolegit86

ok just making sure on the intake. i am just going to run this motor untill i finish my 383 set up. then build this motor, as for now i plan just a mild cam and some heads later. and then put it back in my prerunner

toolegit86

got any ideas on a good intake and cam to use?? i have searched and have had no luck finding a good intake for the motor, most are for vortecs and 87-95 with aluminum heads

toolegit86

iam thinkin on this intake

http://www.jegs.com/i/Weiand/925/817...oductId=746531

here is the casting: 14093638 roller lifters, center bolt valve covers, high swirl intake ports

That only accepts square bore carbs.

Here's a radical idea (which I seem to propose a lot): Since you're building another engine long term, which most likely will not use much (if anything) from your current engine or this 350, consider swapping your 305 heads and intake over to the 350. The 350 will have dished pistons, which your 305 heads with smaller chambers will help to raise your compression. Unless you're doing a cam swap as well, you won't "need" that Stealth intake (which is a fine intake, by the way). Even with a cam swap, a spreadbore Performer RPM won't cost any more than the Stealth (since you won't need to buy a new carb and distributor).

The Comp XE268H with new valve springs would really wake up that combo.

Performer RPM Spreadbore 7104 intake
Head, intake, valve cover, front cover gaskets (and possibly oil pan gaskets)
Comp XE268H cam
Valve springs
Socially acceptable smile reducer (not sure of a source for that)

i would love to do that swap but i want to keep the motor as close to the tbi as i can, cause once i finish my 383 or what ever i do i plan just to put it in and run it. this motor came out of my prerunner chevy.

toolegit86

i just pulled a lifter to find out its a flat tappet, i am thinkin of putting my 461 heads on it i would not mind doing the 305 heads but am just trying to get the best bang for the least $$$ i already have to buy a new smaller 153tooth flywheel and clutch kit just to install.

toolegit86

if i was to run the 305 heads can i still use the serptine belt set up?
and what kind of lift can the 305 heads handle? i am thinkin on doing the swap jsut to get it over with. i dont want to spend money on a intake i will only use once,

You can use the serpentine setup, assuming the heads have the bolt holes to mount them. And just my opinion, but you can always re-sell an intake and get a good deal of the money back, it doesn't have to stay on your shelf after using it once. Especially with an intake, since they don't experience wear or anything really like other parts will

Keep valve lift below .480" with unmodified heads. You'll still need better than factory valve springs, though.

toolegit86

ok. cause i found another set of 416 heads for 50$ in running condition since mine have over 250k on them. just lookin for a the rest of the parts now. once i finish the other motor i am going to try and run the tbi on this motor, and just get a custom chip.

five7kid

iTrader: (14)

461, or 416?

toolegit86

the 416 heads are the l69 305 heads?
i have a set of 461 327 fuelie heads with maney 2.02 vales and guide plates. i was going to run them on my 383 but i dont think they will flow as well as a set of after markets with almost 11:1

what size is the swirl port head chambers?? ive been told they are 65cc but in some cases 76cc

toolegit86

i was thinkin of using this cam, http://catalog.elginind.com/app/Engi...gh+Performance

i ran it in a 355 and it worked and sounded really good. all the way up to 5500k

and maybe this intake?

http://www.kmjent.com/cart/product.p...0164586&page=1
i dont know much about there intakes but i guess there power plus or some kind of brand?

toolegit86

my swirl port head casting number is 14102193, it says they are 65cc chambers

416's were used on '82-'86 LG4 (base V8 4-bbl), LU5 (305 crossfire), L69 (HO 305), and LB9 (305 TPI).

I wouldn't bother with 461's. A set of Vortecs will run circles around them. And you can do even better with aftermarket.

193's are 64-65-ish cc's. The 305 191 swirlports are around 58cc's.

toolegit86

yea i was thinkin of selling the 461's and getting a set of vortecs for my 383 set up.

have u tryed a summi or jegs cam shaft?

as of right now i am having problems with what set up to run?
i have the 305 heads here but they need springs and a valve job, and porting/cam
and still need a intake for that set up.

as the swirls are still on the block and all it needs is a intake and cam

there is a drift comp comming up and i need to drive it!!!

five7kid

Not specifically, personally. I've used Elgin brand of them, though (same things, as I understand). Some people have gotten decent power with them when the combo is just right, but I never got the combo "just right".

Just get a mild cam and slap it in and slap a carb intake on the swirls. You don't need a dual pattern cam with those heads, as the one good thing about them is the exhaust ports do flow well. Unless you keep it below 5k RPMs, though, plan on new valve springs. You might even have issues with factory springs below that.

toolegit86

i actally ran the Elgin E-922-P with just a mild 355 with 10:1 compression and some 76cc heads it ran pretty well actally. all the way to 5k and there cheap like 75$ shipped. i was thinkin of putting the same cam in this motor just to run it.

the specs are: INT.296.444288°214°0° BTC34° ABC69°HYD107° EXH.311466298°224°49° BBC-5° ATC 117°


and this manifold http://www.kmjent.com/cart/product.p...0164586&page=1

and some lifters, gaskets,

i know this is going to sound stupid but do u think the swirls would do good under boost? like 8-10psi,i have a almost complete turbo set up all i need to do is finish the headders.

Drac0nic

I would just throw it in as is and throw the turbo on it. They are flow crippled stock but "can" get decent #s ported from them. Won't matter near as much with the turbo. You may consider a single pattern cam with stocker TBI heads too tbh, they flow very well on the exhaust side.

toolegit86

how does this cam sound for the set up? i am just going to set it in there with the swirls on it just to get it going.

http://www.summitracing.com/search/?...=10000lk&dds=1

i pulled the oil pan to find its a two bolt main. so i am just going to leave it alone mostly..
my father gave me a bowtie 454 finally with eagle hbeams and forged pistons ill get pics soon. so i think my money might go into that.

five7kid

iTrader: (14)

That cam/lifter set would be fine.

Bowtie 454, eh? Holds promise.

toolegit86

yea finally after asking he a ton of times he gave in and thats what i plan to put in with a auto,

toolegit86

I got the motor in the car, i just installed a lunati bare bones cam kit with lifters (summit cost was 89.99) and a comp cams dual roller chain timing chane. and all new gaskets. i just cleaned up the swirls untill i get my 416's back. the motor runs awsome! it actally pulls pretty good. and is strong up to about 5500rpm.

iam runnin my 650dp and a team g high rise. the carb is a little big but still works good.

i am gettin my heads done for free. (nice to have connections) i ported and polished and cleand up the 416's and am sending them in to get cleaned and shaved alittle. and 194's installed. then put them on.

toolegit86

now i understand why u dont run the swirls....

the car was running awsome good power sounded good. had power untill 5500rpm, the whole time it would run at 180 then on my way home it jumped to 240 i shut it down let it cool, no steam or fluid anywhere i just heard it boiling in the top rad hose, after 2 hours i finall got it home. i changed the water pump still sitting there idling for 10min it jumped to 220, pulled thermostat and checked it it was good, gave up and pulled the heads all the chambers were the usuall, then clynders 5,3,7 were super clean, so i figured i popped the head gasket, now i am totally convenced i cracked a head. the is no oil in water, no smoke and the exhaust smells like its fat,

so i am giving up with the swirls since there already off.
today i dropped of my ported 416 heads to get a valve job and cut for 1.94's

toolegit86

and i did get the 454 but i think its going to sit there untill i find a vega, as for the camaro i want to get it back to running condition and then look for a ls1 or better and a 6 speed

I'm finally getting some seat time in my LS1/T56 swap, and I'm loving it. Stock engine with LS6 intake and long tube headers, very easy to drive still it's faster than the street-unfriendly 396 (RIP).

toolegit86

i went fot a ride in a 2000ss with the 427 stroker, dam it was fast and it totally got me hooked, he's now doing a pro charger i am searching trying to find a set up right now, i am thinkin of going to copart and trying to buy a wrecked camaro.

toolegit86

416 heads with 194's installed.

toolegit86

what kind of plugs should i run for this set up?? right now i just have some autolights oe set

toolegit86

so i got it all together,, at first it had less power, but once i started to tune it and mess around with it and better gas its actally pretty good. i might need to swap in a diffrent cam and intake combo but other then that i cant complane. and its going to need better valve springs.

I got the heads glass beaded and shaved and the 194's installed with a full valve job. done for free!!!!

now my new question is do u think it will take a 75/100 shot of nitrous? the heads are ported and gasket matched. i used felpro head gaskets and oem style head bolts. the bottom end is tight and has 60+psi oil all the time.

just painted valve covers and air cleaner to match the out side looks pretty good

five7kid

Cast pistons can take that amount of nitrous. Probably shouldn't be done with hyper pistons.
