Why do the ASA and GTA cars apparently not have these issues?
thx,

I thought ASA ran the "fast burn" ZZ4 motor as the spec motor, carbed...


That and the LS1. Both are limited to about 550 hp.

I'm not an expert on the ASA series. But from what I have seen they were spec motors built by Lingenfelter and maybe others. They had spec cams, injectors, etc.
The biggest factor I think would be they are a dry sump setup which takes care of the oiling issue. Those motors run 6500 rpm all day long in a circle and I think went a full season before freshening. I wanted to buy one off Ebay awhile back.
I still think the #1 issue is oiling and oil starvation, then aggressive tuning, bad engine building. Saw a high horsepower LS motor on Ebay recently from Katech. Can't remember what series the corvette it was in but it had to run a restrictor and still made 550+ and think they said around 700 unrestricted. It had 9,000 race miles on it with a refresh at 5,000.

Brady Morehead blew up a brand new crate LSX motor at TWS. Went from crate to Corvette....lasted less than a session.

Only smoking gun they have is that the negative terminal fell off the battery during the session.

If he can't put the battery in right, are you sure you are safe in applying fault to the LS1 motor?

If I shoot myself w/ a Barret 50 cal sniper rifle while looking down the barrel, do I also get a confirmed kill?

Only making it one session definitely points to an assembly or install error regardless of what kind of motor was installed. I'm sure removal and inspection would point to a direction.

Are those LSX crates dyno tested?
