"We just finished another build today.
.030 cast block stock stroke JLP Basic build with a set of our JLP XR Heads,and a set of our newest Grind cams!..@ 21# of boost and ONLY 14* of Timing she laid down just under 800 RWHP!Also check out the rwtrq! over 750rwtrq @ 140mph!.I was going to put the timing up a bit just to lay that 800rwhp! Number down..But decided not to do it right now..It only has 1.1 miles on it!.....Later on after break in we'll turn the boost up to 25# and push the timing up to 19*..Then we'll see atleast 840 rwhp!(or i'm not Johnny Lightning) he he.So who says these PI heads won't lay the smack down?....Our XR heads and this new cam grind is a combo to be beat" PERIOD!....JL
