With the LTH and VVEL there was not enough back pressure with so much valve overlap to build much boost. I think they said the S/C would only build 4 psi with LTH and CBE.

Sam, I still don't understand why the shop car made 8psi + 450whp and Shumby car is only at 6 psi + 390whp. Is it the CBE or just the tune?
