Inliners International Forums General Discussion Hi Performance Estimation

I have a 66 Ford 240 inline six.
Added some goodies....
cam, Comp 268H
Roller rockers,Comp
valves, head reworked
Offenhauser 4bbl intake
Holley 600 Cfm
Petronix, distributor

Yes it is all going back together and I will dyno. But for splits and giggles, what kind of horsepower should I expect?

What are you using for exhaust? Single or dual outlet iron or headers (describe headers if so)

Compression?
Deck clearance?

Hedman headers

No high rise intake
Compression, don't know yet

I assumed 30-over and 9.2cr, 1-5/8 headers, and guessed at the head, Gonkulator said

That should be a ballpark anyway
