That is what we went for - peak @ 6300.

The car was 2440 with the 351. New configuration is aluminum 302, light T5, light clutch assy, alum bell housing, and ERA rear. Shooting for 2300 maybe less. We Got 150 out of the trans and rear if the rear comes in @ -50.

The 351 was 425. Unsure how much we will improve here, but we should get some.

Will get a little out of the screen and fixed alum drivers seat.
