im building a new 355 motor with speed pro flat top pistons.10.5 c. vette 113 ported heads.. not sure what cam to go with i was thinking hot cam or zz4 cam. but i think the cc503 seems like a better cam.. this will be on stock ported tpi set for now... but hsr latter on... 700r4 trans with 2200 stall and 342 gears. street car.. lite track.
with hsr and xr276hr cam i can say you can hit low 13's to high 12's with a good exhaust i think the part number is 8-503-8 from comp cam id step up the stall a bit to ab 3000 with this cam fora car mainly for the street but u can run the 2200 stall....just wont preform as well but still a good motor
dude, go to compcams and download a program called camquest for free! u can play with your options, before and after, and see what cam is best for your application. try it out, its very helpful.

i went with the gm hot cam because. i found a real good deal on one. im on a buget.. next thing my vette 113 heads have pushrod guide plates.. so i can run normal roller rockers right...
i would have done the CC503 with that setup if you want HSR later on. For TPI the hotcam is a decent choice and will still work great down the road with the HSR
Personally I'd go w/ the 503. It is a better cam w/ better technology than the older style Hotcam. If you have long term goals to get a HSR then get the cam you want for that.
That's what I did. I ran the stock TPI w/ my 227/233 cam for a long time before I just installed the HSR. The car ran fine w/ the TPI and went 13.4 @ 102 w/ the stock TPI a cam that was way to big. Now it will be time to see it pay off!
when i do the HSR i will change cams its just a street car for now. so im trying to stay mild build 350 hp or so if go big i would build a stroker motor.and run a carb. and long tube headers... but thats down the road.
i will problay pick up a nother camaro..
