[FireSale]

Rory: Not motor, block. The Accepted replacement block for the 302 Ford is the BOSS block M-6010 legal in S and S/S.

astikhossw: AFR 1399 58cc heads. Accepted replacement for Super Stock.

The rod/piston combo is the issue for me.

5.090+flat top= 302/230hp(Mustang) or 260hp(cougar) in GT
5.155+domes=BOSS 302/290 or 305hp in GT

My 090 rods are really nice Crowers and my domes are middle of the road Keith Black.

EDIT: With GT based off the heaviest car available for the year, that's 3001 lbs. for the 68 Mustang. With the HP ratings of the motors I can build, it works out like this:
290hp: GT/EA
305hp: GT/DA
230hp: GT/KA
260hp: GT/HA

The K and H builds are at the top of their weight breaks and E and D are mid or low. BOSS is looking more like a hard sell.
