V6 to 350 Swap

[Jaguar_5]

Ok, so my engine is about to die... bad clanking, sounds like the main bearing.

So i want to put a new engine in, a V8, a 305 or 350.

I'm looking for some good reference sites, to help me out with more basic information, like what will fit, what will need to be replaced. Will i need a new tranny, stuff like that. Also will i need to have access to welding equipment to move the engine mounts?

At this point any help will be appreciated

You can start by telling us the year, make and model of the car you wish to do this with.

I can tell you though, that the general consensus is going to be to sell it and get a V8 car. The 6-8 conversion in these cars is very involved. The two different models do not share any pieces in the driveline. Every moving part except the rear end housing will need to be replaced including the radiator, K-member, crossmember, motor mounts, driveshaft, front springs, engine, transmission, PCM, engine wireharness, fuel lines.... The little things will nickle and dime you to death. It is completely impractical unless you have a 100% complete running V8 donor car.

It's a 1989 Camaro RS
v6 2.8 Fuel Injected
Running off the engine: Air pump, alternator... no a/c or mechanical radiator fan
5 speed manual transmission, not sure model number

98% sure it's a V8 body with a V6 dropped in

I know i'll need a new ECM...

Check out www.thirdgen.org . You will find all of the info that you will need to go from a V6 to a V8. There is even a whole board for engine swaps. Just use the "search" button and take notes. TraceZ is dead on, though, you are going to need a donor car.

I've done the exact swap you are looking into. I once converted my 1986 2.8 camaro to a 350. It was the only car project I've ever regreted. It killed me. I wouldnt even consider it again without a complete running donor car.

You will need:
engine - long block with valve covers, oil pan and timing cover
harmonic ballancer
ignition system (distributor & wires)
fuel system (manifold and carb / injection)
Fuel injection wire harness / PCM
Transmission
Radiator and hoses
water pump
power steering pump
alternator
accessory brackets / pulleys and belts
engine mounts
transmission crossmember
exhaust manifolds
y-pipe
limited slip differential (I never had the $$ to do it, so it only spun 1 wheel)
driveshaft
front springs (the V8 is heavier and it will bottom out)
Speedometer (yours only goes to 85??)
Mine needed a entire new guage pod.. it had no tachometer.



I ran a carb on mine so I had to use a holley FPR to step down the pressure. There was a trick to get the return line working too. Even after this conversion I still wanted a car that had the V8 stock, and I had spent a ton on it. My car still had rear drum brakes and a weak base model suspension.

If I had a nickel for everytime....
