Ok guys, I'm sitting at school now so I dont have my cam card or anything handy but I'll do the best I can here. I'm running a Comp Solid Flat 4/7 Firing Swap Cam in my 377. Its supposed to be .520/.540 lift and 244/252 duration at .050. I am also using comp gold 1.6 rockers. When checking P/V clearance we noticed that the exhaust lift was approx .545 and intake lift was .576. Duration was 252 on the intake side, but 258 on exhaust. What happened with this thing? Did Comp screw up my grind???
I have several options here and I was wanting some opinions on what would be the best route:
#1. Call Comp and yell until they replace my cam.
#2. Call my guy at Nickols and send my 1.6 rockers back and get 1.6s for intake and 1.7 for exhaust.
#3. Go with 1.5/1.6
#4. Finish putting the motor together and see what happens. Worst case I break a lot of really expensive parts.
I've had the worst luck with this motor, but according to 2 different dynosims the screwed up version on the cam makes more power than the right one... So who knows...
Here are the specs on the motor... Some things have changed since the last time I posted about it.
2 bolt main 400sbc, .030 over. 4.155 bore
Eagle 3.48 Forged Crank
Eagle 6'' I beam rods
220cc RHS heads, 64 CC chambers 2.02/1.6 valves, comp springs matched to cam.
Victor Jr Intake, Polished and mildly ported
KB forged flat top pistons, 4.5cc valve reliefs
Mighty Demon 850 Carb
Hooker 1 3/4 headers, need collectors...still undecided
MSD ignition (Probillit Distribution, Digital 6 Box, Coil, etc...)
Comp hardened pushrods
Comp Lifters matched to cam w/ the little hole in the center
11:1 compression, 3500 Stall Converter, 4.10 gears, approx 3400lb car. This is about a 50/50 split between track and a street bruiser. I just need a little help deciding on what my best option is here. Thanks in advance.
