Perry,
I've sent details on this before, you may have missed them. The Holley 1848 is
still being made, and is available for about $235, including hot air choke.
What it doesn't have is a PCV tube in the base. I found a work-around. When
done, the car runs very nicely, and an Edelbrock fuel-air sensor tells me my
mixture ratio is good all the way up.
The Edelbrock 500 CFM is a fine car. I have used 2 of the 600 CFM model (very
mush the same, except for bore, and either has more than enough flow for most
uses. IT will bolt right on, and has a PCV vacuum tube fitting, although I
believe it is in the front. Maybe there were two, and you just blocked off the
one you didn't use.
Either is a good choice. The Holley is original LAT equipment, the Edelbrock is
easier to connect to he PCV. DO NOT use one of the two F4B manifold vacuum
ports for PVC, these are for power brake servo only. In fact, use the side one,
not the rear. It is much easier, and actually lines up with the brake vacuum
hose route.
Any of these changes require some adapting of heater hose sizes. Buy some new
hoses from Sunbeam Specilties that are pre-molded to fit your heataer in and
out. You'll need two Dorman 1/2 to 5/8 hose adapters. These are metal, and are
fully submerged in the hoses when connected. One replaces the "T" on th right
side, and the other adapts the manifold heater outlet to your valve.
Buy the 1" longer throttle rod from Sunbeam Specialties, as well. You must have
it for a four barrel.
