this is what im thinking, want to build roughly 500hp 383 for street duty.

eagle cast crank
speed pro hyp pistons
HSR
30lb accel/venom injectors
58mm TB

now my question is the cam and head combo for the HSR...wat would ineed to get my goal 500hp within the limits of the HSR.

i was thinking aluminum patriot performance freedom heads 188cc intake runners, 64cc, 2.02/1.57 valves and max lift (.575) these heads are $800 assembled as a pair cant beat that

cam- comp cams xfi xtreme fuel injection cams,87-93 305-350 O.E. hyd roller 249-08-467-8 (jegs)hyd roller. 280/288 adv.dur .576/.570 lift 2000-6000 rpm range.

what do you think about his combo and how much can i expect from this? if u where to change anything to give me my hp goal wat would it be?
i kno the heads seem alil small but this will be street driven/daily driver, so i dont want a high rever. i would keep the TPI (ported plenum portmatched to SLP runners) and just get a high flow base but i still dont think it will alow me to rev this thing high enough inorder to get the HP, not to mention i cant step on it now without smoking the tires foreverrrrr.

 

Hmmm, 500 HP 383. That's going to take some pretty good heads. I doubt 188cc runner heads will get there. Maybe, but that's about 450 lb-ft torque at max HP, which means peak torque will probably have to be in the 475 range - pretty healthy for a 383.

500 HP would be easier to get with 6500 max RPM. Not sure the HSR would support that. Maybe.
