Curious, and to add fodder for conversation, how about providing more info to help determine those numbers above. Cam type and specs ? And where do you expect the combo to make peak power rpm ?
A friend built a 4.250 stroker with "cleaned" up 87cc Edelbrock heads, no port work, probably about 288 cfm or so at .600", RPM intake, 236 hyd flat tappet cam, Holley 750.... 570 ft.lbs torque and 508-518 hp. It made peak power at 5200/5300 rpm. Similar torque number but shy on the big hp numbers.
My previous 462 with 87cc Edelbrock 313 cfm heads and a XE 254 solid roller and Torker II made 576 ft.lbs torque and 566 hp. With RPM intake the torque jumped to 589 ft.lbs. torque and 580 hp at 5800 rpm.
Very important- what's missing with my personal 462 examples is how the two differant styles of intakes effected the TQ/HP curve. I'm a one finger typest  |
TY for your response. At this time the exact cam has not been determined, Jim Butler is my builder I am going to go see him Nov 15th in person to finalize the engine specs. I want the power to kick in at around 2000 ish and see no real need to go over 6500 PRM's. He just metioned a couple diff intakes and I was just trying to get a feel for what folks have tried, etc.
Thanks to all who have provided input/ideas.
