Moved the firewall back, to allow the front of a 20B to set in the same position as a 13B? Just curious

 

I'll let you know when I do mine.

 

Yep. IIRC, that's how PFS did their first few 20B FDs. It requires relocating the shifter.

that occured to me on the plane, theres room to move the 20b back, on an fc. you end up with more room in the firewall area (cosmo vs 13bt), the sticky wicket is the shifter moving

I have been contemplating this while I was doing the Auto-> Manaul conversion. I have a solution!!!!!

 

There is lots of room to move it back, 3 inches easily, more if it is also lowered another inch or so. Can get mine back 4-1/2 inches. The shifter is the 'sticky wicket'. Thats what I'm trying to figure out. I talked to the guys at autotech and they say relocating the fd shifter forward is pretty easy, especially if the engine has been lowered also. He had no comments on the fc tranny though. J9, how similiar are the tails of the two trannies? Also, what about the clutch slave cylinder location? How is it's location compared to the fc?

 

the fd tranny has the slave on the side of the tranny, its kind of on the rear left side of the bellhousing, the fd bellhousing is about 1" longer than the fc though, due to the pull type clutch.

as far as the shifter goes you have 2-3 options.
1. the 87-93 b2600/mpv have bascially a t2 tranny and the shifter is more foreward, i cant remember how much off the top though. the down side to this is that in the truck they have the tranny tilted, so in an fc the shifter would be slanted.

2. you can cut the t2 shift rod and move the shifter tower forward to the next bolt hole, i'm not sure you could get 4" out of it though

hmm thats all i got
