340 Help. Am I looking in the right spot to fix the issue
Hi
I have a 340 that is 30 over 10.5 to 1 trw Pistons, 1.5 adjustable rockers x heads and 850 thermoquad, yes the carb is fine. Total timing 34 degrees coming in at 2800 rpm.
Has solid compression on all cylinders 190 to 200.
Plugs are tan.
3.23 gears 3200 stall
I have a Crane 150062 cam, attached the cam card.
Went to MoParty and ran it and dyno it. The car was a Dog. Rear wheel 302 ft lbs torque 3100 rpm 205 hp at 4200 and then it dies off.
No power over 3500 Rpm. Goes straight down at 4200.
I think my builder put the cam in advanced could this cause the cam not to react like it should 3000 to 6000 power band
Can it be the distributor going out of phase?
Engine builds power like it should from 2200 to 2400 then the torque curve bubbles up then has a straight decenending line to 4200 rpm where it dies at 225 ft lbs
Any insight is helpful
There is no Crane tech support to let me know where the cam should be installed.
