But, it was freshly rebuilt so...

We went ahead and modified a #1937 Holley to Rochester adapter to work with the 351E's larger intake pattern and dropped the carb on.

Everything hooked up cleanly and other than a non-functioning electric choke, actually ran pretty well for not being dialed in...easily better than the Rochester. We'll tune it a bit over the weekend and decide if we still need the 500.

The chrome will go away when we have time to find something more appropriate.
can you give me more info on how you mounted the 1937 adapter to the larger manifold, I have a 351 and want to do this thanks
