Maybe Erics right, I should buy 3 of Franks LS3's and have a couple spares in the trailer when I race.
I called Schwartz Machine which manufactured the block. To my surprise Bob Cross from GM racing called me back and is sending me a care package. Turns out he is responsible for bringing the ZL-1 block back and actually found the forms in a warehouse the size of and airport hanger.
http://www.gmperformanceparts.com/_r...ckBirthday.pdf My take was it was all the info from the endurance tests and specs they used on the ZL-1 from there 50 hour endurance test in the article.. Should be interesting. Pretty cool having a GM racing engineers phone number.
It's just not quite as simple building this engine. The aluminum block brings in some new variables. For instance the main bolts must be torqued in a similar sequence to an intake but the inner and out bolts have a different torque spec. Also, the bearing clearances are different due to more swelling. It has a steel billet cap and aluminum top half. I could dry sump this block but that just isn't in the cards. Here is the only document that came with the block. Pretty cool stuff....
