h.p difference in heads?
h.p difference in heads? I have some mild locally ported heads with .015 shaved off(maybe 10.4 to 1 comp) and they flow at peak 256@.500 and 257@.600 lift intake and 219@.600 exh. The mid lift numbers are more impressive then peak but the car put down 400rwhp/388rwtq. with 222/222-.566/.566 112 lsa cam.
The car ran the times in sig @ 3650+ lbs (Actually at Southern shootout it weighed 3726 last year) .
I have a good deal on some GTP stg 2 5.3 truck heads with 987 dual springs and 11.2 to 1 comp. These heads on the current car at one time before the bigger cam went in put down 441 rwhp on Thunders dyno with a tr 224-112lsa cam.
What should they do with a c1 cam? I guess 430 give or take a little , but more interested in will the heads make more tq with the higher comp. and run 11.50 with out the cage like I can now get away with
?
I geuss my ? is , Are the gtp's still top ranking heads ?

I just thought I would bring this back up to see what you guys think.
The reason for these stupid c1 questions is I have a chance to get a great deal on these heads and a custom TR228/232-.575/.571-114lsa cam with the heads and his set up when he swithched to this cam was very street freindly. He said as much so as his TR224 -112 lsa cam once in there and a hell of a lot more freindly then his TR230/224 cam.
WIll the 228/232 cam be much stronger then my c1(222/222-.566/.566 112 lsa)?

I would say 10>15rwhp easy. much more if you like to spray.
Well it is hard to just move away from the c1 as so far I have gotten great results from this little cam on a car that has a race weight of 3700+ lbs.
I do think I am going to try the 228/232 cam to see what she runs and just hold onto it for that just incase.
Thanks predator-Z for your time.
