Thread: smallest pulley with the following mods?

3.8

maybe 3.6.

Thats about it.

You should at the least have the heads rebuilt.

To add more to the discussion i'm running a 3.4 on a top swap, ported blower, stock valvetrain, speed daddy's, full size wbs i/c.

No KR in sight on 16* of timing.

Have yet to have any sort of tuning done. Still on my 3.8 pulley non i/c tune.
