you could build that thing close to stock tune it and get 300 -325 horse.

Is that currently what it is looking like it would make with the .030 over, j heads 2.02 and previous cam xtreme comp cams 20-223-3 268/280 .477/.480.
Currently pondering goal on timeline for the 340. Weather is perfect to be driving and enjoying.
