Cam Choice????
am Cam ignorant and don't want to make the wrong choice. I would like to make around 480-490hp with around the same torque.
Specs:
383
Dart pro 1 heads 64cc 2.05/1.60"
Edelbrock RPM Air Gap
Automatic with 3.73 gears
Edelbrock Performer 750 (thinking of changing carb)
I called Crane and they suggested this cam http://store.summitracing.com/partde...2&autoview=sku
Any Suggestions!

No way is that going to get you 480 to 490HP. Look in my signature for my engine specs. I have a big solid flat tappet cam with 252/260 @ .050 and a 540/.560 lift on my motor. It makes 409 RWHP which is right at 480 to 490 flywheel HP. It is a pretty radical idle and would be very tough on an automatic car.

I'm a stick shift person, But I believe 3000 would be all I would
want to run on a street car. you could go into the 230s .050 on
duration with a 3000 stall. having 3.73 gears helps.

that head is a very big head (227 pro 1) for a 383 what is the application street, track, cruiser, are you looking for 490 flywheel or rear wheel. its not hard to make that kind of power, just need the right parts. i think that head would be a diapointment. the cam and the manifod will be out of breath before the heads start working
thanks donni

I saw a build on a 406 use AFR 180 heads and a 230 @ .050 FT hydraulic cam with the RPM intake make 490hp at the flywheel,but I think that was Westec's dyno,which as we all know is off a tad. The numbers you want are reachable many ways though. A good set of heads will require much less cam,but on the flip side a decent set of heads and big cam will do the job also.
I'm in Gordon's camp with decent heads and a big FT solid. I personnaly like the looks I get when I rumble down the street,but believe me when I say running a big cam is not for the faint of heart. Vacuum levels are down,so idle,power brakes,and some low speed torque is affected.
On the other end of the spectrum,I cam pull on to the highway with both tires blazing as I shift into second at 7000,I'm already up to the speed limit.
