    New Guy Here; Hopeful for a Weber 289 48 IDA Baseline Recommendation.

    Thank you. Seems like applying the formula to people’s various combinations, that most folks err a bit on the small side. I think I’m going to go with that 37mm setup as a baseline (less parts to buy vs what comes “stock” in a 48 IDA). I can always go bigger later if I feel like the motor isn’t...

In the meantime, I want to put 48 IDA’s on it, and I’m at...

    Hello from Rohnert Park, California

    Hello! I’m a 60’s Ford fanatic in Northern California. I’ve been a life-long Mustang guy, but I’ve always dreamed of owning a GT40 and (we’re dreaming here, right) a 289 FIA Cobra. I’m going to try and make something happen here with one of those projects in the next couple of years. In fact...
