New Victor340 intake from Jegs
I know I took a car( my current car) that ran 12.23@109 with an M1 and a Holley street/strip 750 carb. 360 with factory replacement cast pistons.
I made ONLY the following changes
very mild porting on the Eddie heads(350 bucks worth)milled the heads 30 thou and went 028 gaskets vice 039 gaskets
swapped comp shelf cam 246@50 for Howard’s shelf cam 260@50…almost identical lifts
swapped to old Holley 950 hp
swapped on Eddie air gap dual plane
car went [email protected]
zero other changes
i am not a believer in the M1 single plane, the Victor on the other hand( and the xcellerator, especially on a stock stroke deal) , imo..really shine.
