if you go with the 307 olds get one with the 5A heads and the stock aluminum A4 intake. They outflow the 7A heads and mainfold. Some early 80's cutlass's might have had an olds 350 option which would get you some killer low end torque. Even better still swap in some early heads (compression & flow)

If you can get by with early olds stuff, you can really make some power with the following: 1976 or earlier 350 block, nodular iron 350 crank, #5 heads, and the A4 intake. Let someone knowledgeable on Olds heads set them up, especially if you have any machine work done on them. The following link may provide some background info.

I have also seen people use the 403 blocks with the #5 heads and A4 Intake. The motors really cook, but you can't turn a lot of RPMs.

Good Luck.

We run a 350 oldsmobile rocket in our Pontiac Grand Prix Pure stock.The research I made shows Oldsmobile-Pontiac- Buick all interchanged in there cars.Our tech man at first claimed we could not run an Olds in a Pontiac car,we told him they put olds motors in the Pontiac after looking into it he came to us with his hat in his hand.This opens the door for us guys saying we can run any of the three.....thinking about a 400 Pontiac motor in ours might even ruffle a few feathers and do something with a Buick.I suggest you research it yourself call the dealers,a cool web site is
