Projects Lil help estimating Horse Power

Starting a project on a 66 Malibu and would like to get an idea of what kind of HP I'm looking at.

283 (compression prior to rebuild 9.0:1)
Power Pack Heads
4 barrel intake
500 CFM holley
Mild cam (327 stock)

Pairing this with a TH350 and 3.23 rear end.

Shooting a nice cruiser that will bark'em when I want too.

 

250+ hp depending on the cam your using....

 

thanks

 

Not a problem! Glad to help..

 

230 at the flywheel. 160 at the wheels.

 

Late 90's I had my 283 on dynoed and had 197 on wheels.
Cam Dynamics 3/4 hyd cam and Edelbrock 7110 dual AFB's.
