Re: My engine build
called comp and they recommended 224/224 .470/.470 or a 230/230 .480/.480 so would this make the .488/.488 234/234 too big for my build?
he said a 236/236 .490/.490 was too big unless i used a 3000 stall

Re: My engine build
ok, did some more research and i think the prob with having a big cam is dynamic compression... so if i get the compression up to 10.2:1 and advance the timing 4 degrees, ill have a dynamic compression of 8.0
