350 hp out of a fairly stock 340

I have a 340+.030 with the 3.58 crank and magnum heads and a mild Lunati cam. Comp ratio is 9.9 and a totally stock full exhaust.
It also has a Edelbrock intake and a 650 carb and I never had it on a dyno but I just don't see it making more than 300.
The 340 Barracuda's and Dart's in 68 ran 14:80's to 15:00 1/4 mile times.

Here's a stock longblock 5.9L with a mild 265 comp roller 4bbl and headers making 350 hp and about 300 hp stock cam.



low cr 360 LA making various hp from 225 hp stock 2bbl setup up to 380 hp with doing fairly mild mods
