Supposedly it's a destroked 6.0L block with AFR LS1-style heads and twin turbos... no C5-R parts.Yesterday Casper was at the track and pulled of a sweet little 6.86 @ 205 right off the trailer which now holds the LS1 et record.
Not to shabby for 352 inches of factory production block and the traditional cathedral port head. Math equates to over 1900 hp at the crank.
In car video with Mike Moran driving.
