Can't see throwing down for an aftermarket block yet.

So for me, a pump gas, OEM production B or RB block with a 4.15 stroker kit is the plan.................after much evaluation of what's out there, it'll be a set of the Indy EZ's. They have the improved intake runner/passage, taller valves, aluminum (weight savings), will fit either my A or B body, takes a wide selection of standard valvetrain/rocker gear and can be ported to MW inlets later.

The complete kit is here.........http://chucker54.stores.yahoo.net/indyezheads1.html
