Steve,
I have the Edelbrock Performer manifold made as a LAT option by Vic.
With the original 4 bbl. Holley 365 CFM carb, and the original air
cleaner size and end plates, it will not hit a stock hood, or a LAT
hood. BUT, there is little room left for any increase in height.
The Performer RPM is a good deal higher than the Performer, and hood
clearance could be an issue. The set-up I have is smooth and performs
well, with no signs of boggy overcarburation.
The reason the LAT manifold changed is that Vic Edelbrock saw the
lo-rise LAT original offering at a race track here in California. He
immediately put together the package I have and put it on the race car
Tiger for test. It worked so well that the LAT team here changed the
LAT option package.
