The 5.3 got a little upset one day and melted the top of a piston....So,
we found a 6.0 Litre and put all the goodies in it from the 5.3 and opened
up the top ring gaps to 30 thou. Should be better now. Josh had it all up
and running again in a week! Has more jam at bottom end than the 5.3 he
The first Holley HP EFI Control unit quit working for no reason. Holley
were very helpful and after a month or two sent us a Second Gen ECU free of
charge. It worked again right out of the box and the old panel fired up
first turn, so we are ready for spring when it gets here.... By the way
the wastegates are now routed to the Exhaust, so no more smoky cab!!!
