I'm thinking down under terms may be different it probably describes what we know as flash I had a 3700 that flashed to 5400 on the hit running down the road (I could be wrong) I got to say I miss it and may go back to it.

Can't speak for Dogsballs, but I only every refer to flash point of a converter.
My previous AllFast 15-090 converter flashed to 5,000+rpm.
Current AllFast 25-090 converter flashes to 4,200rpm.

I've got an L92 to LS3 conversion I'm doing. It will be an E85 street car going in a C5. Thinking I'd want 13:1 to 13.5:1 compression. This will be my first LS build, so no experience; meaning don't assume I know my as* from a hole in the wall. Mainly doing it as just a fun project.
Is there an inexpensive way to get there? Custom pistons my only option?
I'm interested in cheap, because if it gets too expensive, I figure I'll just bite the bullet and go with an ERL dry sleeve 440ci.

Also just throwing it out there, GPI now has a rod/piston combo to net up to 13.5:1CR for LS3 guys.
