Thread: 454 Towing/ Farm truck

Tweet

I have 1986 Chevy 3/4 ton with a 454 and 4.10 with a 4 speed trans otherwise known as a camper special. I use this truck to pull a tractor, pipe, etc. As we all know they are weak and wimpy in stock form. I am keeping the peanut heads because it is a pulling rig. I will also give it a performer intake and headers. I need advice in the cam department. I have built small blocks all of my life and new to the big block world. I have read that the valve guides create clearance issues above .500 lift. I would really like to run this cam:
Brand:Lunati
Manufacturer's Part Number:10110701LK
Cam Style: Hydraulic flat tappet
Basic Operating RPM Range: 1,000-5,500
Intake Duration at 050 inch Lift: 213
Exhaust Duration at 050 inch Lift: 219
Duration at 050 inch Lift: 213 int./219 exh.
Advertised Intake Duration: 256
Advertised Exhaust Duration: 262
Advertised Duration: 256 int./262 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.515 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.530 in.
Valve Lift with Factory Rocker Arm Ratio: 0.515 int./0.530 exh.

It is a Lunati Voodoo. The lift is what I am concerned about. I plan on changing the valve springs for proper seat pressure and so on. Has anyone ran this cam on stock peanuts? Will it clear? The motor has 48k original miles and in perfect condition, I do not want to destroy it. I simply want to improve what I have.
