Block Filler
I have used Hard Block to fill a couple of motors..Both small and Big Block.. I read an article (years ago) about Dave Riolio (SP) that he was using a devcon product to fill motors with and doing big over bores.. 125 over.. This was in the early days of Progas when it was a 9.90 or 9.50 class, and things such as stroked cranks and better blocks were rare/expensive/or just plain did not exist.. Anybody know what Devcon product he was using... Thanks
