Its better, what he has should work. Something else is going on. Tune? Lack of Fuel? Cam degreed wrong? No cylinder Pressure? Only getting Half Throttle?

By the Wallace Calculator this things only making around 425-435hp...... Its a Lame duck IMO

Dave what do you speculate this engine should be making ?

an old 466 I had with blended Iron CJ, similar cam, intake and carb, but more compression was making north of 600 at the flywheel. I'd think this 429 should at least do 525-550 ish. I'd think that thing should be running 6.7-6.9's in the 1/8 mile with out issue.

The times are where his son and myself thought it should be 7.00 to 6.90. All he is asking to get out of it are some 7.20's or 7.teens. Weight of car I cannot say for sure only what he as told me . The car has been overbuilt in my opinion so he may be close on weight !

But again..... Same as with the cam... Whats it actually weigh.

I talked with the owner last night and the guy that degreed the cam in and from the both of them what you have stated is true. I talked with his son this evening and we are going to try and make it Friday night to crossville with his car and may try and take my car to B.G Saturdaynight.
