What clutch are you running, what rpm do you launch at? Going through the traps,...what rpm are you at?

LOL, didn't realize you're in Ohio. I was thinking maybe you were in Lima, Peru.

The SRs I had are not as good as what you have. They flow less than 300 cfm out the box (early castings), you said your heads flow 350+. I did have more compression, but you have 40 more cubic inches (1/2" more stroke). I'm not saying my combo ran this much better than yours and trying to make anyone feel bad, just giving you something to compare it too since they have some similarities.
You can't really compare dynos, but that motor in my car put 508 hp and about 460 ft. lbs. to the rear wheels on the local DynoJet chassis dyno.

I agree with the timing, 30 degrees is too low. You need to be around 36 degrees. CHIP

I run a Ram clutch, launch at 4700, and I don't really know where I trap, but I think iTs around 6200.

And defiantly no hard feelings I appreciate all the help I can get.

Slipper clutch or are you letting the tires spin on the line?

i was slipping the clutch, but if i get another chance to go to the track before it closes i am going to try and be more aggressive.

My thought was since it was a heavy street car a bit more torque would help the car accelerate.I would have limited the cam duration to about 276@.050.The installed cam is fine if the engine can stay in the sweet spot.I The timing should be 34-35 degrees and that will pick the car up alot. Depending on the tires a 4.10-.4.30 would be optimal.I think the others will agree a tall as possible tire is a good idea also.There is enough h.p. to run low 10's if everything is right but I am bit bit leery of the torque output.

it has no problem staying up in the revs, and i run a 28x10.5 goodyear slick. I really think some timing, seat time, and a gear would make my car run like it should.

Since you are running bias ply slicks, I would experiment and try letting the clutch out as fast as your leg will work. Adjust tire pressure / shocks and Launch RPM to get about 1 - 3 tire revolutions before the tires stop spinning.

That keeps the engine from bogging, and results in very good (not best) 60' times and tends not to break anything. This is what a lot of us street car guys do. Unless you run a specific slipper type of clutch, I wouldn't be letting the clutch out slowly, you'll just wear it out quick.

On the top end, look for fuel delivery. I had just run 120mph and the next two runs were around 113mph. Based on my LM-1 going lean in 3rd and 4th gear, I found out that the fuel pump / regulator were going away and not delivering enough fuel and causing it to go way lean on the top end.

I will try that launch technique, the fueling issue though i really dont see it as a problem. The car never loses any MPH, it always goes 123-125. And my fuel pressure stays consistent down the track so i will double check but i think i can mark that off of the list.

I may try and put the cam at 0 or 2* retarded rather than 2* advance and see what that does for me.
