Question for you human Dynos: How much horsepower?
#1
Hey guys,
I was thinking about my Cleveland build and its mods today, and i came to this question:

How much horsepower do you think it makes? I don't have a dyno in my back pocket so i'm left with estimates.

What do you think?(AT THE CRANK)

351 2v heads open chamber
Comp roller rockers
Comp Cam **ADV DURATION.=262 INTAKE, 275 EXH.** DUR. @ .050=218/224**110 SEPARATION**LIFT=.513/.519***
Edelbrock performer intake(dual plane)
Carter AFB 4bbl carb
Balanced crank and flywheel
bored .30
Aluminum pistons(i think)
Dual coil springs (ones a damper)
Long tube headers with Dual Flowmaster Exhaust
Pertronix unit

THANKS GEARHEADSTongue

The calc. came back 370 at 5735 rpm at the crank w/o any accessories ( alternator, water pump, power steering,) at sea level, 75*f yada yada perfect world so I would say 290- 340 depending on how well it is tuned
