Dyno #s, what you think? C1 cam 350rwhp/393rwtq. This is with cyl. 3,4,5 miss fire on the autotap. Cyl 4 was real real bad. 3 and 5 werent as bad but still missfire. Going to check the plugs tommorow. I was happy with my tq, but hp seemed low, but found out I was missfiring. So dont know how much that will help.
98 LS1 motor
C1 cam
FLP headers
B&B tri flo
Ram Air
LS6 intake
SY4000 conv.
It was making 350rwhp all the way from 5400rpms to 6600rpms and then started to drop off slightly. Fuel was 13 all the across the board except at 6200rpms it dropped to 12.8 then back up to 13 at 6500rpms.
Dynoed with my 315s Fikses on if that makes a diff. It was showing timing at 28deg mostly.
Also going to throw on a ported TB, maf, pulley and see how much more that makes. Any advice would be excellent. Esp with tuning issues.
Thanks!

Re: Dyno #s, what you think? C1 cam Converter was locked, automatically at 45mph.
No cats installed.
I like the tq, but hp seemed low. I figure with TB and pulley will free up some more and fix the missfire. But who knows, see what it runs too. The tq and hp curves are real nice.

Re: Dyno #s, what you think? C1 cam Update: Pulled plugs, they were gapped at .60, explains the missfires!
I think what happen is when the motor was out I stuck in the plugs to just seal up the holes while working on it and gapped the other set of plugs and didnt on those... <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Definatly sounds a lot smoother now.
