i6 to SB clutch linkage
I replaced my 250 with a GM 350 crate. New motor is in the correct V8 location. The original 3 speed is staying. I have Hedman Headers.
In the photo, the z bar on the top is from a 68 GMC 327, the bottom is my old one from the 250. New one is 1" too long. the old one seems just a hair too long. the old one seems like it will rub the header. Anyone know what's going on here? Last edited by scott-wisc; 10-19-2013 at 03:34 PM. |

Re: i6 to SB clutch linkage
If I removed the riveted bracket on the frame and reconfigured it mount to the side instead of the top, it looks like I'd have tons of header clearance.

Re: i6 to SB clutch linkage
Mine use to hit the header too I just bent the lower arm on the z bar out so it would not hit the original z bar looks like the right one.

Re: i6 to SB clutch linkage
So I took the bracket off, flipped it around, added more 3/16 metal, drilled new holes, and problem solved.

Re: i6 to SB clutch linkage
Good job! Could help someone else that may encounter the same problem doing a swap.
A little work and some ingenuity helps when working on these old trucks.

Re: i6 to SB clutch linkage
Most of these trucks had Saginaw and or Muncies and for normal use they can handle V8's well. I remember guys drag racing completely stock small blocks with these three speeds.

I haven't driven it yet, but I plan on treating it like a red headed step child. As soon as something breaks, I'll post it!
