I was looking through the horsepower chart sticky trying to get an idea for a build. I was looking at the build listed below and I was thinking about some things.

How would this build be with a set of box stock Edelbrock RPM (292cc) heads? I'm looking at 10.8:1 compression but other wise the build will be identical.

Just thinking about easy ways to pull this off. I want to stay away from heads that require special headers or intakes. This will be going in an 86 F150 and header choices are few and far between.

525-550HP 460ci

Intake System:

850cfm Holley DP Carb professionally calibrated for your application
Edelbrock Performer Rpm Intake Manifold

Cylinder Heads:

TFS street heads with mild clean-up
Roller rockers.

Short Block:

Comp Cam XE284H Hydraulic flat tappet cam or equivalent
(Specs:284/296 adv., 240/[email protected], .584/.588, 110 LSA)
Compression around 10.0:1
Stock crank
Eagle I-beam
High volume oil pump
Deepened oil pan with windage tray

Exhaust:

1 7/8" headers to dual 3" pipes with H-pipe. Good flowing 3" Magnaflow mufflers or equivalent.

Summary:

91-octane. Keep redline to 6500 rpm.
Thanks,
Frankie

Mad Dog headers is coming out with a 2" primary set of headers for this application soon. So headers aren't a problem anymore. From what he said they are going to be fenderwell exit. 8)

I've noticed some headers say chassis exit or fenderwell exit. How exactly do the fenderwell headers run? Do they interfere with lowered trucks?

Shouldn't be an issue with a lowered truck as most exit just under the cab.

I wasnt quite sure how they were routed so I searched google for pics.

Anyone have any thoughts about my build?
