GUESS THE HP?
« on: December 12, 2010, 11:12:10 AM »
Whats up guys, well i picked up a new motor from a friends ex brother inlaw who  got "sent up" so he decided to sell it but he only got a few specs on it. Im trying to figure what kind of hp i can pull with this one. Heres the lowdown tell me what you think. Also i want to change the cam so i know whats in there, what would you recommend for this set up?
383 guts
canfield aluminum heads 2.06-1.60 chambers#23-500-65-0 195cc
1.6 roller rockers
650 holley dp
weiand street warrior intake
msnd ignition on everything not sure on timing yet
hooker long tube comp headers
dyno max bullets with h pipe
jegs th350 with 25-2800 stall converter
mild camshaft (these are the unknown specs but it has great idle and decnt romp)

I found a place in town that as a new dyno so im going to set up an appointment next couple of days and see what it does and let eveyone know who was the closest  ;D

Since the Cam specs and compression are absent,
I'll take a wild guess @ 392 flywheel HP and 420 TQ

We gotta have a compression ratio. That makes a huge difference.

What fuel are you going to run it on? Pump gas/87-89-94 or leaded race fuel 110+?

I dont have the link, but I remember a site offering info that figures it out. You input your data and est HP and torque is shown.
