Quote: I'd want to see 60-70 HP for those changes.
FWIW, my car drops close to .1 in ET for each 10 HP I've added, so I'd think you could see up to .5 in ET improvement as long as the rest of the combination still works with it.
Brad...a .5 improvement would put a HUGE smile on my face! Looking at the cam's duration specs on Dulcich's 448..they seem a little anemic for cnc-ported heads that flow as well as Jeff's do. I'm willing to bet if that motor had my 262/266 @ .050 duration cam..he would have been seeing a bit more than a 46 horsepower increase! Thanks for that info Brent! Thank You all for your opinions on this! Randy B.
