unfortunitely the car can't hold anything bigger then 400 base block. As the valve covers will not clear the hood. The car is a 87 chevy cavalier chassis car so our options are pretty much small block. The budget for the motor is also not very high so we are going to have to make do with what block we have.

I would look into taking the two bolt block and have splayed caps installed. I built a 383 years ago and was not impressed. An engine builder told me the 327's worked so nice because of the short stroke and a longer rod(5.7) when they increased the stroke on the 350 the rod stayed the same, he said by going to a 6" rod and change the compression height on the piston would give the 350 more torque plus these are off the shelf parts so they will not break the bank. That's my two cents which isn't worth a penny.



Just having fun

Forgive my ignorance! I'm guessing a 428 and 434 is a small block 400 based build isn't it! Is there a lot of clearancing issues involved in building one of these strokers?
