Re: Carb linkage pics needed

Ah ok our pedal linkages are different then. What's in that pic is from a '66 Mustang, and the metal piece coming out horizontally at the bottom is part of the stock part, it's an up and down motion. The rod connecting to the bottom of the bellcrank is the start of the custom parts.

Re: Carb linkage pics needed

xctasy, that's actually mine. I must have posted it in another thread a while back. That setup ran pretty well, I just eventually decided to do the 2v direct mount conversion and when I switched to the Autolite carb it had to pull towards the valve cover instead so I stopped using the hard linkage. ...

Re: Carb linkage pics needed

Here's mine back from when I used to run a Weber. It's a bit Frankenstein looking, but it worked pretty well... I had a local speed shop make it for me. A bellcrank attached to the rear carb bolt and then that made a fairly straight pull with the rod to the stock linkage. I've since changed over to ...

Re: Can you spin your tires with non-stock cam and stock sta

You know, that's a good question... I was going off the fact that the person I bought the head from said he had it shaved .060 and cc'ed at 54.5, and then from there used the 2cc per .010 estimate. But the first numbers can't be right - .060 should have brought it to about 50cc.

Re: Can you spin your tires with non-stock cam and stock sta

Agreed, I put a 67 valve body in my 66 with a shift kit, and it made a huge difference being able to hold the car in gear longer and get those sharp shifts. I downloaded a dynamic compression ratio calculator and played around a bit, and it looks like with some estimated numbers my current DCR is 7....
