Will be a 11:1 6" rod 383 with Edelbrock Etec170s, Edelbrock Vortec TPI base that has been ported, Siamese ported SLP runners, ported factory TPI plenum, LT1 throttle body, Doug Thorley tri-y headers, 2.5" dual exhaust into a dual in/single out muffler with electric cutouts. Finally I am using the Lunati Bootlegger 224/236 @ .050 cut on a 108* LSA and it will run on E85 with a flex fuel sensor. The ignition system is EFI Connection 24x with Delco D585 coils.
Timing table is not hard on these setups. Provided there is NO knock activity it will run on the high octane map.
