Ran a 392 for 18 mths till the Eagle cast crank let go.

I used ported 360 heads peak flow to 240cfm at .550 lift.

Off the shelf headers, M1 SP off the shelf, comp xs282s sold (520 , 245@.50)

3.89 gears, 3400 stall, RMVB. 800 AVS carb, 3650lbs with me in it.

Ran a best of 12.3 at 111mph with a dogs$&t 60 ft of 1.86,

Loved the torque for street duty and there was def more in it.

Just use a decent brand crankshaft and forged slugs.....Icon 846/847 are good.
