Holley ID
 
Can anyone help me ID my Holley? Or send me to the right website? It's a 700 double pump with mech 2nds. The numbers on the horn are LIST-4779 under that is 2506. The primary metering body is stamped 6541 over 4779. The secondary metering body has 6543 over 4779. Thanks in advance.

I'm not sure what's left to decode. Sounds like you have it all, let us know what you want.

Gofast now that you say that it does seem like a silly question. I picked this up after it was already modified. I'd like to know what it had in it origionally. What it came off of. It's got different Venturi Boosters, and shooters. I haven't torn it down but I'd bet the internals are different too.

Well, I looked it up in my Holley book.
4779 is a 750 cfm,
model 4150,
75 jets in front,
76 jets in back,
85 power valve,
.025 front shooter,
.032 back shooter.

This is all can give you. Not sure about boosters. Good luck with that modified carb.

Thanks Gofast! I was told it was a 700 with 750 boosters. I really dont need a 750 on a 351C. But I dont think it will hurt. I was trying to figure out what was inside, before I had to tear it down. I'm getting a pop out of the carb, sometimes followed by a puff of gas, when comming off the line. I checked the timing and it's fine , not a backfire. I thought it might be that the carb was running lean causng the pop. Any thoughts or advice would be appriciated
