i am building a 383 stoker and when i am done with it i would like it to be putting out between 450-500hp and close to 500 ft lbs of torque but i am not sure what camshaft to go with i was looking at the GM Hotcam with 1.6rr at .525 lift but i am not sure if that will get me to my goal any suggestions on other cams. i dont want anything to radical.

 

what type of lifters are you planning on using?

 

comp cams oem roller lifters
P/N CCA-850-16(summit racing)

 

I'm not sure if that cam is gonna be enough to get you up to 450hp. I myself have a 383 coming next week and the cam that I picked is a GM 350-Hi Performance cam with 236/242 duration @.050 and .539/.558. I ran a bunch of cam combos through DD2000 and **** one gave me the highest average HP and TQ between 2000-5500rpm. Ofcourse I did this with the flow numbers of the heads that I'm gonna be running. To me, I think that is the best use for DD2000..effects of different cams.

Are you staying TBI with the 383???

 

First off heres some things you'll need to tell us before you can get a real answer:

1) What heads are you using?
2) Compression ratio?
3) What kind of induction?
4) What gears and (if auto) stall?

Also, whats your intended purpose for the car? Daily driver? Do you care about performance more than gas milage and drivability?

With some real nice heads I think you could make about 430-450HP with the LT4 hot cam but I think your torque goals will be lower than you want.

 

If you have a 10:1 cr, 3:73 gears, 2.02 heads w/190cc intake runner,and you want to use a mechanical cam I would use this Crane Cam which would work nice in a 383.

FYI There can be some clearance issues with a stroker running 5.7 or longer rods and big cams.

 

ANYTIME
you build a High Performance Engine it should be check for clearance. Dont Assume anything. Rod to Cam (.050-.060), Rod to Pan Rails,(.050-.060), Valve to Pistons (.035-.045). This SHOULD NOT be new to any Experience Engine Builder.
most of the guys probably won,t admit it but theres not a single guy thats ever built several engines that has not screwed up something some how so don,t feel bad just learn from your mistake
Id bet more than 1/2 the guys did not carefully check all the clearances durring their first cam swap,Id bet more than 1/2 the guys did not carefully check and degree in their first cam,3/4 of the guys never checked quench, thrust bearing clearance or lifter bore angles on their first engine build and Id bet 7/8ths of the guys did not pull all the oil gallery plugs and clean out all the oil passages with a rifle bore brush on their last bearing swap, theres something about human nature that makes us only learn the hard way ,not from OTHER PEOPLES mistakes so don,t feel like your the only guy to ever make a mistake, just LEARN FROM YOUR MISTAKES,TAKE NOTES,
