hey everyone i just bought a 98 with a v6 it blown. my question is that i have a built pontiac 400 sitting here in the garage and would like to know if anyone else has tried this swap and if so are there any good sites and parts to help this build along? any help and or suggestions would be greatly appreciated!

 

I don't think a pontiac block is going to fit at all. Just to get an old school Chevy Small block in there is a big project that requires the use of a sawsall.

 

The Pontiac 400 is a w-i-d-e engine. And a small block is tight enough in there. I don't see the 400 happening without modifying the inner fenders, which is a can o worms that could involve clearancing the strut tower too. If it's been done easier than that, I'd like to see the finished product.

 

Well that is not what i was wanting to hear lol. i suppose i could look around for maybe a chevy 350 or 400.

 

Here is a 350. This one has a tubular Fame section so it sits as low as possible. Its really going to be tuff to work any anything that has a distributor in the back and a cowl hood is a must.

 

i guesa guy needs to have a response on file. these cars are motor spacific so if u have a 3.4 its best to stay with a 3.4, even changing to a different size 6 can be a nightmare.

 

screw it im going with the pontiac 400. when done i'll post pics and details

 

"Have sawzall will travel". Can't wait to see it done!

 

Should be interesting to see how he handle the fact the strut towers and exhaust manifolds want to occupy the same space. I realize they are not strut tower but they do support the weight of the car. I'll bet the oil pan will take a good 5 hours of fabing just to get the motor to sit in.

Might want to check a few things with a tape measure first.

 

Since he's gonna have a "Frankencar", maybe pipes like these will work? Just a little hood clearancing should do the trick!
