gross hp-255@4100rpm, and 376ftlbs torque at 2600rpm.
175 net horsepower I think.

1970 f-250 custom camper special,aka "the tank"390 2v,richened,
timing advanced,hacked up air clener for better flow, dual
4 foot 2-1/4" straight pipes, np-435, dana 60 4.10 rear.
1/4 mile in sixteen flat,and the thing is in need of a rebuild!

For '72 the net hp dropped to 165, compression took a dive.

Hey Big Block, can you tell me about how much HP and Torque I'm getting out of my 352. I swapped in a 4 bbl cast intake, edelbrock 600 cfm carb, and 2 1/2 inch dual exhaust with V-force mufflers??

think a 352 has 170 net hp stock, I'm into
390's,.352 beats a 360 for sure
though. Never been interested in 352's since
there is a whole yard with fords holding
390's a couple blocks from the house,
there is some one known as rat smoker who
can do desk top dynos,
