Tom , thanks for the information .
I just picked up my 1st block ( thanks to Bill from this site ) a 425 which I have been studying quite a bit .
What I,m wondering and maybe you know , does the 401 block have thicker cyl walls than the 425 ?
I going to pick up a few more of these engines and take the blocks to a guy that builds my race engines for my dirt modified , He has a sonic tester to check wall thickness .
I,m not going very wild on the boost on this engine it will mostly be for looks and the additional music from the blower belt .
I,ve always wanted a car with a blower and I,m really thinking this car will look great with one .
When I talked to Carmen ( which was,t long ) he made it sound like head gaskets sealing was one of the main concerns . So when I get closer to doing the build I will be contacting him again .
Appreciate all info. I can get from you guys .
