Sorry for this hijack, but I just gotta know. Is that Indy a spreadbore manifold, or did you mod it to fit that carb? Thanks for enlightening me.
The Indy is not a spreadbore and WHAT carb is under there , I see no mention of one ???
There is probably enough meat in the intake flange to make it fit a spread bore.
The intake is really designed to be put on a head with a max wedge port window, but it is delivered with a stock port window, the runner is max wedge size and doesn't really taper to stock port window so the flow isn't as good as it could be.
