hellz NO!!!!!! lol
it would have been much smarter ($cheaper$) for him to go that route...MUCH cheaper!;)
but no where near as cool...

Maybe Erics right, I should buy 3 of Franks LS3's and have a couple spares in the trailer when I race. :goofy: 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. :unibrow: 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....

That is pretty cool Todd. Can't wait to see the results, as always with what you try to achieve. I saw the price on that though...:faint:

As far as injection goes, I don't have any immediate or future plans. I'd need to start over from tank to engine on my fuel system. I feel the carb is easier to deal with in a racing enviroment. It's easier to keep two bowls full than 60psi behind every injector ALL the time. Plus, I just chapped my wallet anyway! Is there a group for this sickness?

Thats good news on the springs. Did ever get a chance to weigh the car before you pulled the motor? Interesting to see how much weight it will shed off :yes:

I think you should think a bit more about a dry sump and not right off that idea so quick.... it's only money.
Super cool on the Gm contact.

Christmas came early for Todd!!:cheers:

So no LS9?.............................................. ....................:lol:

j/k......it's going to be bitchin'!! :thumbsup:

An all aluminum BBC is top shelf in my mind! Rember the Red Witch.....yeah, pretty bad ass!! :yes:

Queston, what do you think it will weigh? And what savings over the last iron block build? And what does this compare to an AL headed SBC and an all AL LSx build?

I think you're right Monza -- let's not let him WRITE off the idea quite so quickly. I'll personally kick in $100 bucks for a dry sump! Who's in with me?

LOL

According to GM specs there is a 150 lb difference between a Gen VI 454 block and the ZL-1 block. That's pretty significant. I'm pretty sure it puts me within 100 lbs of an LSX and should be comparable to a small block with aluminum heads. EVERYTHING under the hood is aluminum as well. I guess I should look into the dry sump option a little more. I already have plans for a road race pan, windage tray, and scraper. Keep in mind that I also have a 3qt accumulator. I wasn't having oil pump pickup problems with my street strip pan and accumulator that I know of..... I've got to cut myself off somewhere. :unibrow:

Damn dude.... Your car just keeps getting more and more cool. I liked the car before, but this makes it just nuts.

Oh, and I'd go with the guys on the dry sump setup. Or are you saving that for a reason to take the car apart again in the future? Anything not to be "done", huh? lol.... They're never done.
