I have a 280 comp cam, holley 4 barrel carb I think its 600 cfm I forget the numbers on it, hooker headers, flowmaster 2 1/2 all the way out. 289 heads, 302 block. I have a 289 performer intake, will this be ok or do I need something else?
Just where do you get the idea that a Comp Cams 280H won't work with stock heads? If you continue to believe that fantasy, then I've got a bridge to sell you While it's true that better heads would net you a larger increase in performance with that cam, you WILL see a gain in performance EVEN with stock heads with the 280H. Not everybody can afford better heads along with all the other improvements you may deem neccessary, but most CAN afford improvements to their engines that a better cam, intake, carb, headers, etc can bring. I've run the 280H in a couple of motors, and both had stock heads, and BOTH had vastly improved performance with it. Damn, I'm glad you've now told everybody that I had a cam I didn't NEED I'll have to go back and pull the cam and go back to the stock one.Max Power said:LOL! Comp is sure selling a lot of 280s to people that don't need 'em!
Been there, done that!
RPM is better, but might not be worth the $$$ to switch if you stick with stock heads.
Your question shouldn't be , "is this something I NEED", but rather "is this something I WANT" ,when pondering the effectiveness of the Performer intake you have now. In my opinion, the Performer's only advantage over the original cast iron stck 4 bbl small block intake, is it's construction----- aluminum. Otherwise it's really just a carbon copy of the iron one. If you want a better intake, then go for a Performer RPM, or better yet ( in my opinion) the older Edelbrock F4B, Fords old C9OX, newer A321, or the Cobra high rise. These intakes have been on the market for longer ( ecepting the RPM) than many StangNet members have been on this earth. They DO work well with stock heads, and big cams. This has been a known fact for 30 or more years now.steel1212 said:I have a 280 comp cam, holley 4 barrel carb I think its 600 cfm I forget the numbers on it, hooker headers, flowmaster 2 1/2 all the way out. 289 heads, 302 block.
