That Holley we've been chasing turned out to not be the #4412 Holley 500 we wanted. Working with a friend that had what he thought was a 500 off of a boat and bought it sight unseen. My son picked it up today and looks like we have a 300 or so 2-barrel Holley...I need to do some more research.

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.:lol:

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
