Machine Shop recommendation..L.A.

Here's a simple build that should get you around 340+hp out of a 360.
KB107 at 9.5:1
stock 1.88-2.02 heads with good machine work, stock rockers
XE268H cam
LD340/RPM/Air Gap
750 Holley
Headers
Good electronic ignition with good initial/total split.

The performer intake is a pretty decent intake, not quite as good as the others. I'd still expect it to be in the 330+ range with a performer 318/360 intake.

IMO, the Lunati 60403 268/276 cam or whatever the new number is may perform a bit better.
