Not Ranked
I've got a 393 stroker and I just had it dyno'd at the spring fling. It's got a comp. cams cam. I can't remember the part number now, but it's got .541 lift intake, .544 lift exh. Duration @ .050 is 246 degrees. Heads are Cast Iron ( you read it right, not Aluminum) Roush 200's. They have the 2.02 intakes and in my mind cast iron = virtually bulletproof. I have the Edelbrock Performer RPM intake and a 700 cfm Edelbrock carb. Out of the box, the Edelbrock carb is jetted spot on. I could possibly go 1 step leaner on the main jet, but I'll leave it alone for when it gets cooler. I've got 3.55 rears which will affect hp on a chasis dyno. I start making 350 lb ft torque at 2600 rpm and it stays above 350 until 5250 rpm. Peak torque is 398 while it pretty much runs at 380 from 2900 rpm to 4500 rpm. Horsepower is very linear with no flat spots and peak rwhp of 360 is at 5500 rpm. This is a very basic motor with stock rods and Keith Black pistons. C/R is about 9.2/1. Check the rpm range for your cam first and if it's near the 1500-6500 range go with the Edelbrock RPM. In addition, the Edelbrock pro-flo air cleaner (tri-oval in shape) has NO RESTRICTION below 1000 cfm. My dyno runs proved it.
Best of luck,
Jim Downard
