Hey guys, I have found an amazing deal on a 355 motor. My question is what is needed to run it in my 92 rs camaro? Will it bolt to my wc t5? Etc. It is a 4 brl Holley carb, so I would be going from (tbi) toilet bowl injection, lol, to carb, please I could use the info, motor is rated at 340- 350hp, thanks.

 

There is a tech article linked from the thirdgen.org homepage about converting from EFI to carb.

The T5 will bolt to a 350. Only question is what type of rear main seal your 350 has, which will determine which flywheel you need.

 

That's a good question, idk much right now about the motor, it is in an early ninties s-10 and it is bolted to a 700r4 tranny, I believe.

 

I read up on the efi to carb article, seeing as how I'm pulling the entire complete 355ci out of the s-10 and pulling my motor, the only part I really need to follow would be the fueling system, right? Bc of it being a carbed motor it already has the distributor and intake and carb, well I would also have to follow the throttle cable info and all too, but that should be simple. My question on the fuel pump would be, could I just use my tbi fuel pump and get a regulator, or do I definitely need to get an older pump, a carb pickup or whatever?

 

Since S10's never came from the factory with a V8, the engine could be most anything. If you can get the casting # off of the block, that would provide a good deal of the information needed.

You can use the in-tank electric pump with a return-type regulator. The story on a factory TBI pump is it can support about 300 HP on its own. If you use it as a pusher pump to an engine-mounted mechanical (with a return-type reg after the mechanical), it should be able to support more.

 

Ok, one more thing, I read something bout the key, ignition key, that it has to use the ECM, is that true? Or can I junk it? My key is the key with the little microchip in it, I'm also using factory guages, so what will I have to keep to make those things work?

 

If you don't have a computer ( not needed for carb ) then the VATS ( chip in key ) no longer works.
All you have to do is bypass the starter enable relay that was operated by the VATS

 

How might I do that?

 

There are a couple of tech articles on VATS.

 

What's the consensus on return-style'd in-tank pumps? Living on borrowed time, or will they last?

 

If you don't know when your pump was replaced, you're probably on borrowed time.

 

Could you please link them up here as Im in the same perdicament as Badrs and am going to be swapping everything from my 85 to a 92 V6 RS as its a milllion times cleaner of a shell than my 85.
