if you want ot use a pt88 and spin it high then stick with a 347. 347 should shift around 7200 with a pt88. 370 around 6700, 408 around 6200 before back pressure starts becoming an issue.Originally Posted by SLO TRUCK
thus why you need to plot your setup out
my twins on the LS2 only plan to shift at 6400
2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
2002 Silverado - 427Lsx w/ Twin gt4202s
2010 Silverado crewcab Z71 - 5.3litre w/ procharger
2000 Wrangler - 5.3litre with some stance
2014 Xsport- 3.5 Eco boost
412 Motorsports
it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
