does anyone know the stats on the stock roller cam that is in the 305 in 1991 ? I was told it is only like a .335 lift dont remember the duration. I might just save my money and leave the stocker in it for now and just get the good exhaust with some flowmaster 40's on it. that should sound decent. at least until i can locate a big block to swap in. 396 or 454 any day over the 305 =) I just need to get it running, the wife dont think i can do it, so she said if i get it running that we might be able to increase my truck budget =)
