What size is the bypass fitting on the intake manifold

[Judge Mills]

Have a 318, Edelbrock Performer intake... It's almost time to start this badboy up, just need a few odds and ends...

Nevermind, found a thread on it.... 3/4" ....

Ummm........ I bought one that I thought would fit... wrong size... it said 3/4" HOSE, not fitting.... Fitting was 1/2"..... Can anyone tell me the size for sure, since I'm going back to the parts store with my tail between my legs? I"m already returning the alternator belt for the 2nd time....

3/4 or 7/8?? bump

Found one that is 31 bucks.. YIKES that is spendy!

Mopar Performance P4876374

Any other suggestion? That costs almost as much as a lokar throttle cable!

15 bucks from jegs.... in anodized blue....

The small one is 5/8" and the big one is 1". The threads for the small one is either 1/4" NPT or 3/8" NPT.

Oops, just realized how old this thread is.
