Holley Sniper - use Man-A-Free Riser?

[Mars]

Hoping for some wisdom on this… Installing a Holley sniper on a 1976 2f. Original truck had a Weber carb and a stack of spacers.

Moving to the sniper, I have it mocked up like this. Heat shield with spacer, then the man-a-free, then the adapter mount that the sniper sits on. Gives me about 2-3/4” from manifold to bottom of sniper.

Too much lift? Any issues running this set up?

No experience with a Sniper, but I think I have older manny spacer under my Rochester that came that way in 82. My thought is more mixing distance for air/fuel is better to some extent. I also have one of those tungsten screens in the path just under the carb - not sure it really helps with mixing but it does prevent big stuff making it to the pistons.

Hi, curious as to how this worked out. I also am replacing a weber on a man-a-fre adapter with a Sniper. Who did you guy the Sniper manifold mount from? I'll send a PM as well. Cheers, Jerry

I would grind that Man a Fre spacer to port match the Sniper plate and take that middle bridge down to a knife edge.
