Indy EZ, talks the talk, walks the walk.

On the next go around it will be less with different (dished) pistons to be pump swill (we have 93 here) compatible. Want as much cam as the heads will allow to be run on the street on swill.

This will probably be the end state motor for the KOS Demon. It is going in right now with the 13.9 build, but that C-16 $$$$$.

Well your heads can use a cam as big as 278/280 and .700/.700 which I have personally run on 91 octane and 11.5:1. Can't say how long the lifters will last with those spring pressures but it will need the $800-$1000 ones.

If you want to stay around 400-440# over the nose you can run a lesser expensive lifter ($450-600) for a long time and a roller cam 250/250, .600/.600.......but your heads are better than that.

Compromise, compromise, compromise.
