Maybe I should just shut up, but unless you have a lot of expertise, my experience was putting on an
edelbrock (4brl?) caused some problems,,,,,,had my engine completely rebuild by a real expert (often won't take car engines (mostly international race boats) , bored .060 and because of my
Holly float leaking that wouldn't stop and another fellows problems identical to mine, someone suggested putting and
Edelbrock on which I did. When the engine was running, it was way too rich and the smell of fumes was heavy...….Have since learned, that one must play around with the jetting to get it right on that
carb and significant messing with the throttle linkage to get it to clear the
intake manifold which if you let it rub as is might result in the linkage sticking at full throttle.
Holly has solved the float problem with their newer carbs.....I called
Holly's "expert" number and after answering specific engine questions, they sent me a
carb that worked great right out of the box....although the one issue was the base gasket they sent wasn't the 4 port kind, but the open type and my manifold (stock) required the 4 port #56...…..Luckily, someone found one here locally.
Good Luck with your project...………..
