I have a 300-6 in my 85 f150. Been doin some motor work here lately. And I'm just curious to know how much power/torque I'll be putting out.

Standard block and internals
78 f150 head ported and polished with stock valves
comp cam .456 lift .260 duration
Offenhouser intake ported and polished
Autolite 450 cfm carb
And if it matters 4 speed OD trans with 4.10s on 35s. Any ideas here folks. Thanks

Should give you a baseline idea

 

That just told me how much from the factory. At least what I seen. Did you go to something special?

 

Exhaust?

The only way you will find out is to Dyno it. I'd say not much more then stock.

 

Theres a Dyno place close to me I planed on going to. I just wanted to see if someone had a ball park idea.
Exhaust wise it's just header with 2.5 inch all the way back
