Re: Ordered the Holley Sniper

There are folks that have them in stock, you just need to check around. The vortec heads are not tolerant to timing and need 32 to 34 max and 4 to 6 degrees less then a standard small block in the curve. You will need to build a map for it before you try and run it. Do as Holley says in the instructions and get it running first with out timing control.
