I plan on eventually doing a 383 build up for my car and after looking around at other peoples set ups I put a list of parts together. How does this list sound?
383 Shortblock
AFR 180cc heads 64cc chambers or Edelbrock 185cc with 64cc chambers
Comp Cams 280 Magnum Cam
Edelbrock Hi-Flow TPI Set up
Will the aftermarket tpi set up be too restrictive on the motor? Will 1 5/8" headers do or would I need to go up to 1 3/4"
Will I need a bigger throttle body? What size injectors would be needed? Thanks and any ideas would be really helpful.

 

64cc heads on a 383 with flat-top pistons would be close to 11:1. A 12cc dish would get you around 10.3:1, which is much wiser, even with your choice of cam. If you're going to spend money on an aftermarket heads and intake combo anyway, the Lingenfelter/Accel SuperRam was designed and intended for the 383. In which case, go with a 195-200 cc head. Going TPI on a 383, with moderate cam and compression can easily exceed 500 ft-lbs, but will be no fun by 4500 rpm. If this is what you want, your cam is too big. If you want to use that cam, get a SuperRam, MiniRam or StealthRam. For heads, I'd say AFR 195s or Dart Pro1 Platinum 200s.

 

The car will only be street driven with only a couple visits to the track. Does anybody else have any ideas on how to make this build better. I would like to keep the car TPI. How hard with this be to get tuned?

 

Magnum grinds have been around forever. Look into Comp's XFI series.

 

Definetly go with AFR 195s or Dart Pro1 Platinum 200s or even WP Sportsman II 200 64cc heads if this is mainly a street car and occasional trips to the track. You will have thr grunt needed for street driving and some good mid-range torque. As far as cam, I would contact isky, comp cams or whatever brand you prefer and let them tell you the best cam for your needs. They may need to custom grind a cam for your needs. Also try to keep compression less than 11 to 1 for street driving and being able to use pump gas is a benefit. You'll also want 1 3/4 in primary headers with any of the above heads to breath good.

 

Sportsman 2s are obsolete, and there are better heads for cheaper. As for headers, the 1 5/8 won't be a restriction at your power level if you stay with a long-runner intake.
