i am using the springs that came with the self aligning set that i bought a while back witch they could stand up to a 550 lift. I just dont see those rockers making me lose that much 15hp. I mean i guess it is possible but even with the 1.5's, i was expecting more. Are they considered stock if they are aftermarket comp's 1.5's?

 

Whoa, I am sorry, I thought you meant the stock 1.5 Stamped Steel Rockers. Nevermind.

 

which even makes it worse lol... now that you know that.. the guys seemed to think that it was very good for the lt1 and with that cam, pulled off some good numbers. they are use to their 11 or 10's cars though so who knows.

 

what shop was this? LG??

 

What was the seat pressure open and closed of the springs? If the closed seat pressure was much less than 130 #s then you could have an issue there, I know the cc305 w/1.5s is only at 510 lift but you may have some valv control problems. I think your torque is very very poor. with the 291 hp if you had had 320 or so torque with that hp and your mods I wouldnt have thought much about it, but since your torque is way off It raises the flag, what has this dyno done with other cars? high , low?
is your tranny in good shape? was the tires slipping etc?

 

Is it possible you adjusted the rockers too tight? I know with the hotcam kit rockers I've adjusted them a couple times now to get them right, the first time I did it I went 3/4 turn past zero lash which apparently was too tight, the car would barely pull out without stalling.

Don't feel too bad about those numbers, I made 267rwhp and 279ft lbs torque with the mods in my signature. It was a mustang dyno, and my AFR is around 10 I definitely need some tuning.

 

Comp Cams Pro-Magnum Non-Self-Aligning are the 1.5's that we used and they said they tighten them down to 1 turn past zero lash. I asked them if that would hurt the cam at all and they said it wouldnt affect it any. The shop is MODERN MUSCLECAR TECHNOLOGIES" in rockwall texas. My tranny isnt in good shape so that might affect my dyno i hope. the guy that does their valve work is an awesome guy from what they said, he picks up around 6cfm's or so on every job he does if it is just a clean-up deal. i had a bent valve and he fixed that and does the pressure check on every spring. so i am not sure though, i am gonna scan my car this weekend and see why my SES light comes on only when it is in park and not in any gear. but, i was hoping for around 310hp at least....

 

I would drop the valve adjustment back to 1/2 to 3/4 a turn past 0 lash.

 

camaro, i feel much better now lol.... does the car run good though?

 

You know thats really the litnis test. If that sucker feels and runs good who cares about the Dyno, My 93 only Dynod a little over 350 hp and 370 torque but it could run low 12s all day long no matter the weather.

 

Yes the car runs very well and feels much faster, at least that is what my butt-o-meter was telling me. I was expecting a lot more too when I took it to the dyno.

 

You know just switching from a 1.5 rr to a 1.6rr is like a .0300 lift gain. That is what that cam is made for. The hotcam with 1.5 rr is .492 lift and with the 1.6 rr it jumps to .525 lift! I'm sure the cc305 is fairly similar. That is alot of power right there.

 

Ok, I have the graph here with me... my peak power was at 5300 rpm??? This doesnt sound right at all with this cam. The guy said it could have something to do with the way the cam was installed.... for instance dot to dot would be the cam was installed top to bottom or something like that at 2 or sideways at like 0 this makes no sense to me what so ever!!!!! my a/f ratio seems to be great though 13.1

 

I think he was implying the cam was installed retarded, but the LT1 timing sets only have one set of timing marks . If its installed straight up it should have no problems, my cc305 headed LT1 peaked at 6200 rpm.
