Dyno'ed My 360..it's a pig..what next?

stock hi compression 340's were only about 280 and that would be around 190 - 200 at the rear wheels.i don't think your there with a lo comp. 360.
..i think Gumper is correct.. and that transmission is a power robber too.
..Dynos can really vary,some getting unbelievable power where it doesn't seem possible.
