well first i did do searches, adn got more confused, so now im asking. my question is what parts should i look for in my 350 build. it has been pulled from a mid 70s scottdale. my intenions with the car is a daily driver, but still have the horses to beat almost anything on the road. Starting from the bare block what would you guys recommend to put in there, also a side note is as more money comes in ill be trying to upgrade it. the current trans is a t-5 with 3.42s rear end, if it helps any. thanks anyone and everyone who helps me

 

Daily driver that will beat almost anything on the road - that's a pretty tall order. Especially with a T5. "Daily driver that's not embarrassed at the track" would be easier and more realistic goal.

What induction do you plan on using? I assume you have TBI now.

Assuming the shortblock can be rebuilt, keep the crank, just have it turned if necessary. Have ARP rod bolts installed and have the rods resized. Assuming the block needs to be bored and can be bored, go the next oversize and get hypereutectic pistons with about 12-16cc dish. Have the block zero-decked (the machine shop should know what that means).

Upgrade Vortec head kit like so http://www.sdparts.com/product/SD806...RPMAirGap.aspx . Assuming you're going carb, that is. Comp XE268 cam & lifter kit, Holley 650-750 DP carb. Vacuum/mechanical distributor, proper fuel delivery & management (such as return-style fuel pressure regulator) - you'll probably have to drop the tank and either remove or replace the in-tank electric fuel pump.

 

sounds good five
but i have carb and im thinkn of reuseing the factory induction from the fi engine i had, ofcourse ill fab the thing up, but thats the way im going. the idea on the block and everything sounds good, but 2 questions
1. which disturber should i look for?
2. which header should i use? im goning dual cat exhuast 3"
thx for the help five

 

Which factory induction would that be?

Any EFI distributor would work, assuming you still have the harness for the EFI.

Hedman makes a good set of dual cat hedders. They only come in emissions-legal style, though. Another option that's becoming more popular is the custom sets member Dyno Don is fabricating. He only makes his in 1-7/8" primary tubes, if I understand correctly.

 

umm...the thing thats behind the front grill, then the air goes up into a flat tube thing...lol i dont now how to describe it, but if u look at a v6 fi engine thats the one

and the wiring harness, well it got fired, dont now how, it was a nice then my frined did for me

and parden me but im dumb in techinal terms, but 1-7/8 primary tubes? umm wuts that mean?

 

Sounds like a TPI system. You should be able to find a replacement harness either in a junkyard, on the thirdgen.org classifieds, or eBay.

Header primary tubes are the ones coming off of every exhaust port. The larger they are, the more high-RPM power you'll make and the less low-end torque you'll make. 1-1/2" are good for trucks, 1-7/8" for larger small blocks and higher output small blocks. 1-5/8" are the "middle ground", and pretty popular for supporting both reasonable torque and power. The Hedmans I mentioned are 1-5/8".

 

oooo ok thank you five

new harness, ok, im looking for a wireing harness for a 1988 carb right?

ok sounds good on the exhaust

thats pretty much all i needed, thank you five

 

There were no carbs in 88, but you don't need a complete harness anyway.

 

ok...so then i need tbi harness? sounds good i wanna go tbi but question is can my v6 fi comp. be reprogramed for tbi v8?

 

Wait, wait, wait! Hold yer horses. Are you saying you have a V6 now?

That changes everything. First, you can't use the EFI system from it on a V8. Second, the computer won't work on a V8 system (unless some serious modifying was done, which doesn't make any sense since a V8 computer is so easy to come by). Third, you don't want to use your V6 T5 behind a V8 - it's weak, the clutch parts aren't exactly compatible, and you're just asking for headaches.

So, we really need to understand what harness got burned up. Most likely it's the one that you'd need for a carb conversion, but perhaps it's just the part that goes to the ECM.

We really need to understand what you have and where you want to go. Need to get the ducks in a row here.

 

hmm guess i should of metioned it, it WAS a fi v6, but the motor blow up, and it was a 700r4 in it, and the v6 harness, i think, is fried. sorry i didnt metion it.

and i have a v8 t-5

i DONT have a v8 harness for anything, but i was told that i could reuse my v6 harness, altho that "freind" has been proven stupid...so ya.

sorry for the confusion

 

ok well im offically a noob when it come to tring and finding stuff on the internet, and apperently cars to, but first umm..where can i find that cam at? 2nd what kind of lifter kit do i need? and lastly whihc kind of distuber do i need? i am going to get a tbi system i guess.

and a stupid question can a mechine shop do all this? i mean get eeverything i need and build it up?

If you have a V8 T5, that's good. You'll need a V8 bellhousing if you don't have one. The flywheel will be for '83-'85 f-body V8 application (don't let 305 vs. 350 throw you, they're the same thing).

There are basically two harnesses in the engine compartment, one that goes to the ECM that routes through the passenger fender well, and the one that provides power, gages, etc., that goes to a firewall bulkhead connector in the rear driver's side corner. There's another for lights, etc. If the ECM one is the one that got fried, then you can run a carb system on the other. If the one coming from the firewall is the one that got smoked, you'll need to go to a junkyard and get another one.

TBI would probably be one of the more difficult ways to go. You'll need the entire system from the ECM, harness, sensors, and TBI unit itself (either a 350 or 454 unit), and then PROM tuning equipment to get it to run right. If you don't need to pass emissions, a non-computer carb system would be the simpler set-up.

A machine shop could rebuild the engine and assemble it. Most machine shops don't install, and in this case convert, but there may be one around your area that would do it all. The one guy I know who does machine work and install only machines heads - he sends blocks & cranks out to pure machine shops, then puts the engine together himself.

 

oooo ok thanks five, for the info and link.

umm i think it might be the ECM one that got fired, b/c my ligths and htings stilled worked, but its all for a v6, will the wires, and what little senors i need, work with the 350?

and ill stay carb, theres no need for emissions on my 88, antique vehicle law thingy, bascily it say i can do what ever i want but can only drive 5000 miles a year...but theres always loop holes anywas

and this is roanoke, i now someone around here can do all this, but ill probley put it together just to now it.

 

Dark, you need to find a book on this stuff, buy it, and read it until it's memorized. Pay close attention to spelling and grammar while you're at it for an extra bonus. This is semi-complicated stuff you're dealing with here if it's to be done right. Either take it to a mechanic and tell him to fix it for you, or do lots and lots of reading to understand how to do it yourself. Not sure why five has been holding your hand so firmly thus far, but I doubt it's going to last through an engine swap considering your ignorance on the subject, and lack of communication skills.

Forgive the brutal honesty, but it needed to be said.

 

rihgt...thanks for the , but u find me a book that tells me how to do all this, i will gladly buy it and leave you to ur world of smarts, and as for taking it to the mechinic, the reason why my v6 is blown up is b/c they f***ed up real bad, and they got out of fixing it b/c of some little technicallity. and five is probley helping me b/c hes a nice guy, mayb he went tho the same thing, or seen its disasterous results if not done right, and just wants to avoid seeing it happen again, who knows but im happy he is helping.
and as for my ignorance and lack of comms., ok so what if a little missunderstanding is here or there, live and learn, sorry if i wasnt born a car god who nows eveything...im only 19 and still learning, and also thats why i took mechincs class, so i could understand more

sorry for the brutal honest response, but it had to be said
