Hey all
I have a 4v Holly carb swaped up from a 2v motorcraft. This is the first time Ive delved int 4v carbs. I got this Holley off of a 390 cid T-bird block in a junkyard. It work awesome when i put it on my 302 cid mustang block. However it leaks like a sieve. It been in storage for about 10 years. I have to rebuild it which I am not afraid of attempting. However, I cant find the model number on the carb. There are several numbers but really dont know what Im lloking for. I bought a rebuild kit from Mustangs Unlimited for what they call a 54/78
need some help
Thanks
