another wasteless thread what is this shit. you made all that up didnt you, who in the right mind would use a FORD front end.

on the honest side, stewart thanks for sharing that, i think any hot rodder builder should have this sheet printed and hung on the garage wall. that would be very handy. along with the small block chevy casting numbers saying what year, size of motor etc. Yeah I SAID SMALL BLOCK CHEVY...

by big dogs 42 on February 8th 2008, 4:35 am

Thanks Rebstew Riggs is right about the rear end measurements and the Chevy boys need those casting numbers for replacement parts cause those chebby motors keep flying apart. lol!

I think i said enough!!! :rabbit:

I think Jeff has some of the MFG'rs codes for the gear ratios for some of the older 8" Fords. It might be nice to make a work sheet stating Mfg, year, code, and gear ratio. I don't know how easy that would be, but it might make a good club wide project. That way when you go rearend hunting at a yard, you can make the search a lot easier to find a specific ratio.

by JRiggs on February 8th 2008, 5:03 am

if any one is interested, i can print this off if you want it to be laminated throw a $1.00 into the club funds or race car project and ill laminate one for you.

pm me if interested
