I have a 2.8 V6 with the 4 spd overdrive. My friend has a 87 IROC with the 350 4 barrel, How would I swap the engine and what stuff do I need and to converte? By the way, The tranny in his car is also a 4 spd overdrive

 

You will need v8 motor mounts.Take everything from the other car and put it in,including the drive shaft.Just check out the articles and it will be a snap.

 

Well it's my buddies car and he is putting another motor in, He's giving the motor out of his IROC to me. So I guess a trip to the boneyard would be a good idea, Do I need any wiring harnesses? ECM? Fuel lines? Exhaust?

 

Fuel lines and exhaust would be a good idea. It's carbed, so an ECM isn't necessary. Try and get a bellhousing from a V8 TH700-R4, so the V8 will bolt right up to existing drivetrain. All you would have to do then is get some V8 motor mounts and the necessary V8 y-pipe. It should be easy.

 

FlowTech makes a header & Y-pipe combo for small block chevys

Goto http://www.summitracing.com

Type in the part number: "BIG-16102"

This should cost only $202.69 Relatively cheap for what you get. Then you will have the extra hp & torque of headers and a solution to your y-pipe needs.

You could just goto a salvage yard and pick up a y-pipe, but they'll be hard to find anymore. Whatever you do, Good luck

 

since when do GM automatics have a removeable bellhousing?

 

if he wants to stay legal, it is

 

Dude, you don't have a clue.

Camaro_1986_19, think of it this way: If it bolts to the engine or feeds it, it needs to be changed. The engine itself is the least of the problem, the rest of the list is extensive: transmission, engine mounts, radiator, accessory brackets, harness, ECM, sensors, carb, distributor, fuel lines, brake line, hoses, cables (throttle, TV, & cruise), air cleaner, front springs, exhaust from heads to rear bumper. Even the tachometer. If this needs to be emissions-legal afterwards, the list is longer and the task more difficult.

The best way to do this is with a complete factory V8 donor car. "A trip to the boneyard" should be to get such a car (complete), or else, more realistically, it'll be "many trips to the boneyard". The car should be the same model (Camaro vs. Firebird), and should be as close to the same year and with the same equipment as you've got.

The driveshaft and rear end do not have to change. If the transmission is the same type as you currently have, that is.

 

Ok automatics aren't able to change bellhousings, I know that wtf did I type that

However I just did that exact same swap in my buddy's 88 Formula, he had the MPFI V6 and we swapped a 383 with a non-CC Q-jet. Amazing, he passed our sniffer test here in Vancouver without having an ECM.

EDIT: He also passed the visual inspection. I guess they didn't notice the carb sitting under the open element air cleaner.

 

haha, good laugh. Anyway, I think that you should stick with the ecm, just get one out of a V-8, they shouldn't be too terribly hard to find in the local "crash 'em & stash 'em" salvage yard. They might even have the all the ECM's torn out and organized already.(mine does) Then you also are going to have to get a wiring harness from the V-8, that could be the tricky thing. Expensive too.

On second thought, if you don't need the ECM, don't worry about it.

 

What would u guys recommend? Getting my V6 rebuilt and putting a racing cam in for 600 bucks or getting the V8 put in

 

I'ld go V-8, but that's just my opinion.

And if you do, make sure you get a 350, I wouldn't waste my time with a 305. My RS had the 305 stock, while it was a decent motor, it wasn't very great and it isn't an easy engine to get more than 300hp out of.
