Besides the gas what was the reason you blew your motor? To lean?

only conclusion i can come up with is,weak piston from the factory...all the bearings look good,no signs of detonation,everything looks like brand new except for that one piston....it looks like someone hit it with a sledge hammer....lol

Hey, billy. Since you're just doing this for fun (I think)....would you try something for me,if you can? I've got an old HOT ROD MAG (Feb. '05) that compares the EDY dual plane to a GM single plane with 3 different cams on an LS6 engine. Cam 1 is stock ZO6..#2 is 228-232 on 112 lsa..#3 is 228-232 on 110 lsa. The dual plane hangs with all by quite a bit up to 5500. But here's the thing....they try several different spacers on both with very little gain on the single plane but they say a 1" open spacer made a bunch of difference in the mid range on the dual plane. I'm hoping you might have one to try. One other thing...all of the cams had their torque peak around 5000-5500 RPM. If you have 4.1 gears and 28" tires and you're going 100 mph in the 1/8 mile, you should be in that range depending on convertor slippage. Wish I was there!!! Ron

Billy,
I am following this close. I still haven't gathered enough parts for my engine yet so I have been keeping an eye out for your posts to see how you do.
I would really like to know what a pair of L92's that have been milled 30 would do with the stock setup and Z06 cam.
I ended up with a pair of nice L92's that have already been milled and have 660 lift springs. What sucks is my motor is a 99 6.0 with the dish pistons, I am sure this is going to hurt the performance. I still need to get a set of ARP rod bolts and new head bolts.

thats a good question about the small cam and a set l92's...i've heard people say with the size of the heads that it will hurt the low to mid range performance...but if you got a loose converter it really does'nt matter...my motor is dished piston also....i'd like to try a set of l92's with a bigger style cam...but i think a set of 799's or 243's would be a better performer for a street style car with a smaller cam...imo

I pretty much agree with everything you've said above, especially the part about the loose convertor! As billy knows, I have a stock bore 6.0 with L92 heads and a mild cam 222*- 234* @ .050....551 lift on a 112 lsa. Mine probably has 10-10.5 compression. I have always thought this engine was "soft" on the low end. Above 3500-4000 it pulls like a rocket! I don't have dragstrip times, but I do have a way to compare times on what I call my "test facility" LOL. I have raced several cars in the past and this thing would not do well in 60ft or 330 times. 1/4 times would be a different story.As billy said....a loose convertor in a race situation would completely change the picture. My covertor is only a 2800-3000 stall. Don't get me wrong, this thing is OK on the street but is not what I expected it to be.I agree with billy.....use the L92's on a BIG engine or on a small engine in a race situation with a loose convertor or manual trans and use the #243 or #799 heads on a street style car.

This one I hate to post. Iwas WRONG about the #799 head. I was just sure the chamber was smaller than my #243 heads, butwhen I checked it yesterday, it came out within about .6 of a CC of the chamber I had checked on my ZO6 head. So... apparently they are basically identical to a #243 small chamber 65 CC head. My bad!! Ron

there are even reports of some z06 cars having a 243 on one side and a 799 on the other...

That would be really weird to find on your new vette. Probably would have freaked me out!! LOL

victor3ranger

Billy,
What I would really like to see is what your old cam (motor that blew) in the stock 6.0L with the dish pistons and a set of .30 milled L92 heads would perform like.
I am having a hell of a time trying to figure out exactly what cam to go with in my setup. It will be a track only drag car, around 2800-2900lbs, th-350 manual trans, 4.10 gears and 28x10.5 M/T slicks.
All I want to do to the stock short block is flycut the pistons if I have to, swap out the rod bolts for ARP's.

i would'nt run my polluter cam with a set of l92's...the reason being it seems the l92's like more of a split duration type cam...but if you want to run a proven cam with the l92's and a carb setup check out dmmizzels 6.0 foxbody...thanks billy

Hey, billy....once more........

something like a 249/252 around .6teens to .620 lift on a 108+2 or +4

Only reason I say that is i;ve tried diff combos on my stock bore 6.0 and this is what I got the most out of, although my f body is 3199 w no driver in it. 4600 converter, 28/10.5, 4.86 gear(too much gear).

my cam is a cammotion custom grind 249/252 .620/.612 108+4
