Thanks for the feed back on my T-5 conversion I do not have a rear end yet but the info you gave me is pushing me toward a 3:55 ratio. I have been looking at 3:73,3:55 and the 3:08 gear ratios. I have all three lined up just waiting to decide,I was looking at numbers but when you calculate everything into the equation, I know you have to look at the big picture,not just the numbers, and with your feedback it helps to see a little clearer. The one with 3:55 needs to be rebuilt, any ideas or suggestions on where to get parts for rebuild. It's a 56 chevy rear end. My project is a 53 chevy station wagon that is going to have mild engine performance. MY main goal is to get good gas milage because I will enjoy driving it anyway. On a previous post Gearhead suggested a rear end out of 55-57 cars may fit without modifications and it measures just right.
My real dilema is the clutch set up I just came from auto parts store and there is a cluch disk for a astro van for the 4 cyl that is a 9 inch disk, with the 14 spline that will match up with the tranny. Is that cluch disk going to be able to handle my wagon? I did not see the disk for the 6 cyl they were out, I am assuming that it is a 11 inch disk. Do I need the 11 inch disk with the 11 inch flywheel, or can I use the original flywheel and pressure plate,and go with the 9 inch disk? Thanks again for your feedback and help
