Tom good hearing from you. You are right we are trying to do the best with what some of us have. The Aftermarket block is just not always possible logistically or financially. There are lots of guys that have a machine shop sponsor and this setup works great for them. There are lots of guys with nitrous street motors that this setup works great on. Then there are us drag race guys. I raced my Cuda with the same OEM block and aluminum main caps for a dozen years with no reline bore. In fact it is still together in my shop albeit I have not raced for several years. That motor went 9.20s at 146 with ported cast iron 915 heads that I still have and went 9.0s at 150 with ported stock size window Eddy's. My goal is to run high 8s with the same motor 452 and run low 8.s with a new 510 inch that I am building with the same port window Eddy's As far as I know there was not a faster OEM stock stroke block OEM head car out there for at least a ten year period. That motor was NA no boosters.
