1971 Match Race ~ 'Duster 340' vs. 'Boss 351 Mustang'

I stuck a 351C from a '72 Cougar into my '68 Mustang coupe.
It wasn't that fast.

....because it just smoked the L60s on the back like they weren't even there. Including at about 70 on the highway lol.

Not surprising, since in '72 they dropped compression quite a bit. That combined with the huge lazy ports of the 4v heads made a huge difference in low speed torque from the '71 engine.
