280zwitha383 Posted September 7, 2007 Share Posted September 7, 2007 I've heard of these high-dollar aftermarket retrokits for fitting a roller cam to the older engines. And I've heard of using some non-SBC GM factory parts for retrofitting as well, using lifters from a V6 and such. I think both of these methods are used for older blocks. I'm not quite sure what you mean though. Are you talking about a direct piece-by-piece swap in from 87+ roller equipped block to 87+ non-roller cam? I think you've got it. 87 and up blocks should be pretty easy to come by and if you can get oem roller lifters and all the needed stuff for about $100 then you're that much ahead I think. Like I say I would recommend getting a vortec engine just because you've already got a roller cam. You could even sell the heads and get some money back if you don't want to run them but for 400hp and under I think they're just the ticket.
