Lee: My block has a cast rear cap but it looks to use the bb chevy seal
so would you call that a in between block ??
Ron Tarabori: can you try and resend the info on the heads?
Im thinking of half filling the block with hardblock and running it at 4.030 ... but I'll know more once its sonic tested
I have a bms crank at the shop now getting cut to 2.100 rod journals and a final stroke of 3.7 ... it was a 3.625 to start with
(main reason it had bad spun bearing damage on a rod journal and I didnt want to have it welded ) besides sb rods in all different lenths are easy to come up with
If I can get 4.030 safely it will net 283 cubes ... looking to build a real fast pump gas combo ...maybe toss a alky kit on it for a lil extra fun

Im sure I'll crank it up a time or 2 to see what its made of but mainly want to not have to push it real hard all the time to go fast
picked up a fast system with wb to handle them duties
Im use to big head big cam high stall sb chevy cars so driveability is not a real issue for me
