Ended up making 775 hp with the Wilson ported Indy intake. Not bad for a pump gas engine using OOTB cylinder heads.

The Indy intake was 15 hp better than the Mopar M1 intake (both are fully ported by Wilson) which seems reasonable given the Indy is a MW port size while the M1 is standard port size.

The vacuum pump was worth 15 hp at 15 inches of vacuum. We didn't play with the vacuum level, just ran the pump right out of the box. There is an adjustable relief valve on the pump but I didn't touch it.
