Here's another, less agressive example that may suit your application better. This one uses less cam and less static compression ratio to make good power and excellent torque.
355, Edelbrock 185 heads, RPM intake, 1 5/8" long-tube headers, 9.5:1 static compression ratio, CompCams solid flat tappet cam, #12-222-4, 224/224, 0.499"/0.499", advanced 2 degrees and using 1.6 rockers on intake and exhaust. This simulation uses your 650 carb. You could make another 30 hp with more cam, but you'd give up this beautiful torque curve....(over 400 ft/lbs from 2700 to 5700)....(over 450 from 3700 to 4900)....
RPM HP TQ
2000 144 377
2500 182 382
3000 234 410
3500 295 442
4000 349 460
4500 393 460
5000 427 448
5500 435 415
6000 407 356
Comp recommends their #981 single spring with damper, 370 lbs/in rate and installed at 1.700", 105 lbs on seat.Last edited by techinspector1; 03-25-2009 at 03:47 PM.
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
