For sure the Predator head is a great thing for us. Boat's motor being just another example of what you can do with them. I did a 636 with them and they're better than anything else I've had personal experience with.

Trouble is, you see small block chevy aftermarket heads with bigger ports lol. Not knocking predators by any means I'm thrilled about them. I have a 660 pred waiting to go on the pump. I'm hopeful about what it might make, but when you see the over the counter Chevy based stuff out there, it can be a bit deflating.

Thanks to Steve Gill for getting it going for us poor old mope's. Also love'm, or hate'm, Indy does make them available with a phone call.
