I’m thinking the 288/302-111 might cost a little bit of peak tq output........ and I don’t know if the vac pump will be enough to equal that out or not.

I guess we’ll find out.

Another 14:1 572 made 766tq. That one had bigger heads, the 3X intake, a little more cam, and a fairly ineffective vac pump(4”).
Even though the peak tq was less, it did end up making 40hp more.
