Need help with cam selection.....Carb, stock heads,stock bottom end The block is a '89. I cant afford heads even though it would be the best to start with. reason im doin the camfirst is that it needs a timing chain doesn't make sense not to while im in there. My buddy has e-303 cam but not enough lope. I want good powerand a good lope.It's gotPerformer rpm intake and 670 avenger carb. long tube headers soon to come. Here are some ive looked at already. Open to all suggestions any feed back greatly appreciated.

f-303 512 512lift 226 duration
XE513513 224 230

 

I would look at the Comp Cams list and go with something in the .510 lift, lots of power and will lope great, work super with stock components, and don't forget the lifters for it.

 

Another guy said same thing and that i might need longer push rods??? Is that true?

 

Look into comp xe270 hr-14. I went a 13.2 with just a intake manifold, that cam, longtubes and 4.10's. Makes some decent power with stock heads.
