I am waiting to inquire about anyone the breaking cylinder walls on 400 blocks while drag racing. The main reason I ask is that it seems like more guys are building B blocks than RB blocks today. I would prefer that only those that broke post replies. Hear say I am not interested in.
My friend John Armenoff (If you're in Indiana you know who he is) raced 470" B blocks in the 80's and early 90's before switching to RB blocks. He ran them in Colts and later Daytona's.
In the 80's he was racing at least 3 times a week and running 5.90-6.00 1/8th mile times in the early days and running 5.50's later on in the Daytona. The engines saw 7,000-7,200 rpms. Aluminum rods, lightweight pistons, and a roller cam with 282 degrees duration @ .050" He told me he went through 16 blocks during the time he raced them and finally switched to RB blocks and never broke one of them after that. I just keep seeing all these B block builds, but never hear of any broken blocks. What say you that have real world experience?
Thank,
Tom
