He talked to whoever cut Kevin Wyum's gears (4.77?) for him. I don't think they were local.

It's funny that this subject pops up again and again over at TC with no resolution. I'm pretty sure it's because the market won't support the expense.

I'd be curious to hear what a company like Richmond Gear would have to say, just for ***** and giggles.

For us FD fold the Cobra 8.8 rear is an easy solution. Once you add up what it costs to get 300m axles and a Kaaz diff it's about a wash price wise. And being that the mustang aftermarket is so damn large there's an array of available gear choices if you happen to change your mind about the ratio you want. Sadly, I just changed the ring on mine last weekend for the 3rd time without them ever seeing the street.

Add nicely ported 202 heads, 12:1 compression pistons, a long overlap, high lift solid lifter cam (the long overlap reduces the mechanical compression at lower rpms by a bunch, which is how they live on pump gas), single plane intake and big carb, and you can twist a streetable 302 chevy to 9k on a regular basis. Oh, remember the good dual valve springs.

Well, that's what he did back in the 70's with what he had. Thanks for the tip.

I'd love to see what he used to build them up. All the ones my friends and I built were back in the '70s and early '80s. it was much easier to find good 327 blocks then.

Today I'd probably also use good modern aluminum heads that'd handle compression bettter and have better flow. (and of course, weigh less).
