To much cam??

Exactly, Rob-that's where I was driving. He installed it straight up, so advancing it would likely help out. What I've seen is timing sets (what kind, did he use?) that actually retard timing a few degrees-as much as 6* with stock type timing sets or low budget double rollers.

I'm actually kinda waiting for younggun to come on here and say we're all overreatcing. :) since he's running a COMP 294S Magnum grind in his 383 with 84cc Edelbrock heads. But I think he's running more stall and more gear...pretty sure those Eddy heads are about a good 6cc smaller than the 906s too.

here i am! lol. you are correct. I do have an even bigger cam in my otherwise stock bottom end 383. the math puts my engine in the 8.8-9.2:1 copression range. my cam is .254 @.050. it is a huge duration for the short block. I know that if i were to tear it down and put a new cam in i could prob get a little bit more power out of it but i just dont wanna tear it back down. I am running the 84cc eddy heads with a single plane m1 intake. all that being said. i know my combo is all wrong. i built the engine when i was 19 and was just buying go fast parts from a catalog. live and learn. they are correct about the timing. my cam is installed at 106*. it was degree'd. when i first fired the engine i had about 10* initial timing and 35* total. the thing was a dog. it had a huge overly rich idle that would burn your eyes outta your head. i got the dizzy reset with the help of cracked back. i now have 22* initial and 36 total. the thing starts up with the flick of the key and sounds nasty as hell. could it make more power? sure! but it runs pretty damn hard and does well enough that i enjoy it. keep in mind though that i am running a 4500 rpm stall converter and 4.10 rear gears with 28" tall tires. my opinion is that your cam is in retarded, your have too little initial timing, not enough stall converter and not enough gear. it all comes down to what you want from the car and what you can live with.
