....Thanks for the imput everyone .... hummm, I'm having my 413 small block rebuilt, 9:75 to 1 compression, AFR 195 street heads, 1 5/8" headers, 750 Double pumper {The Carb Shop is rebuilding it to Stage II spec's meaning it will be built to match my engine}, Performer RPM air gap manafold. This engine used to have a cam w/ around 222 to 224 intake duration {it's been so long that I don't remember exactly} & 232 {or was it 234?} exhaust duration. Lift was around 515 w/ 1.6 rockers. It put out 438 HP @ 5250 & 499 TQ @ 4000 RPM. The guy who built that motor said if I had a litttle bit bigger cam I could pick up HP w/o really losing any TQ. It's a street/strip car, 2500 pounds, turbo 400 trans, 9" rear end {current ratio is 3:00, but I'm going to go lower, 3:50/3:90?}, with a converter that stalls between 2200 & 2600. I called Comp Cams twice, said I'd like to pick up some HP but not give up much if any TQ, once they recommended a 240/246 duration cam, second time a 238/244 duration one. These cams call for a 2800 stall converter but they said with 413 cubic inches that I'd be fine. I pluged these numbers into my Desk Top Dyno & the TQ went WAY down. Then I asked the guy building my motor {he has LOTS of small block experience} & he said 230/230 would be perfect & definately no more than 236/236. He also said NOT to go with a split duration cam because AFR heads flowed really good on the exhaust side {70 tp 80 percent exhaust to intake all the way through the RPM's}..... Anyway, so that's why I was wondering about Comp Cams recommendations..... Thanks again, ;0 Bill
