Well that's the $3000 question if you are going to a 2800/3000 stall later and will live with some driving through the converter OK but degree it in at 103 (give or take 1) and it will be much more pleasant now and when you go more TQ. Will your heads and valve springs take that lift?? They should. I ran a .509 old stock but went stiffer P3690933 after valve floating.
