Camshaft Manufacturers Description:
Headers, dual exhaust, large cfm carburetor, performance ignition and increased compression of 10.25:1 and above is required. Cylinder head modifications would be beneficial. Use with automatic transmission with high stall torque converter or manual transmission.
Close attention to proper ring and pinion gear set and tire diameter is imperative.
Lifters, Crower "Cool face" #84326X980
Intake, 4x Weber 44 IDF for a total of 1169.2 CFM.
IR Intake works differently than a 4V Holly type as each runner only has to handle a single colum of fuel/air and one cylinder will not "Rob" an adjoining cylinder. The individual cylinders also have less air mass to move so this engine should rev up like a superbike!

Lots of custom fabrication to be done, particularly for the JAG IRS, front body/hood mounts, and functional cowl induction.
I will try to document each step of this build.
This El Camino is for my own use as a true GT car that happens to be capable of hauling light loads.
