wormboy did it years ago.. 396 with afr heads.. pinned caps, 1/2 studs, and filled block.. they were running a 91/98.. it took them a while to get it to live.. i think the main problem was the caps not being pinned.. i'm sure they had the block o-ringed, but now a days the double o-ring is the way to go..
370 inches, 88mm here. gotta be atleast 3250 for a class, gonna see how light we can get it though... gonna find out this year what it will go. i don't think 8.70's or maybe even a .60 is totally outta the question at around 3100 or so
it was a 366'' ls2 with a Callies Magnum crank,GRP alum rods,Je piston, ETP 225 heads and a solid roller cam. Had a 98mm turbo. I think it would have went faster with a 94. It came up on power too slow.
