I've been waiting a while to post this information, but I've been working closely with a company to cast a new high performance 7.3 block.

These blocks are going to feature

- High grade casting material (same as used in NASCAR and Pro-stock blocks)
- Billet steel 8620 main caps with splayed bolts on 2-3-4
- main studs are H11
- proiority main oiling
- Larger oiling flow to hpop resevoir
- Larger main webbing around crankshaft and cam tunnel area
- siamese bore cylinders
- siamese bore water jacketing
- extra thick deck surface
- significantly thicker cylinder walls
- thicker pan rails
- screw in freeze plugs

We are working out details right now as far as price but it looks like it is going to be around $4000-4500, obviously the more we have ordered and made the less they will cost, we could get the cost as low as $3000

Let me know what you think!!!:ford:

will this block solve the big hp block spilts and ripping the mains out of the blocks?
Why do you wanna know? :D
Time to step it up again:)
Yeah - Maybe we can now find out which is really breaking- the "rods" or if the mains(block) is giving out first.:poke:
don't hold me to this, but i think theres been a few cases where after markets rods has held and the mains ripped out of the block, and rods were checked out and still good to use and straight
I am in need of a broken block or two...
The engineers and I want to address exactly where these are breaking.
I have seen many pictures, with them broken from the mains to the cam tunnel, but we need a couple for further evaluation.

By the way... dry blocks will be available, these should be very good for the puller guys.:D

will the blocks be returned? i have on here that i use for mock up
