I am looking to buy two as ONE will immediately be modified to work with Holley 2 barrels (500 cfm
rears and a 350 center).
These carbs will easily bolt down with adaptors
(I have done it, Bill Klausing at my suggestion did it, and a few others).
If you are going to use an aluminum manifold EVERYONE who knows pontiacs will recognize that it is NOT stock so the restoration comment is not
valid unless you are going to paint over a perfectly good manifold.
This same question was asked on the edelbrock heads when they were first proposed and hundreds of heads have been sold since. A lot of High flow
E heads are on street cars that could run ported stock heads for the normal driving the people do BUT the people want the aluminum heads.
Holley sells the Holleys at about the same price as the core cost you mentioned for the rochesters and you get a new carb. (Plus parts are easy to buy for them anywhere!) Just my opinion. Tom V.
ps If Chris wants to donate a new manifold, I will be happy to show his customers how to modify it to run Holleys.
