Hi! My tan 62 is done!! I'm on the road and having fun. All is well, it drives like new (it had better!). During my ground up build I started down several paths: I installed an M4F cam w/ the intention of installing the dual intake and fentons later that I have on the shelf. It's running the stock 261 w/the correct big rochester for now. Behind it is the HD SM420 that came with it. I installed a 3:38 when I rebuilt the rear (from a 3:90), again w/the intention of running a saginaw 4 speed which I rebuilt but then sold. (I was going to do the Patrick's conversion.) The truck runs out fine, 1st is granny low, 2nd and 3rd go by pretty quick too (I can't imagine how quick they would peak w/ the 3:90) 4th gives me good hiway speed, I'm breaking it in so I haven't gone above 55-60, but it has more. I get this feeling though that this combo is mis-matched. Any comments? I still have my 3:90 gears or I could put a 3 speed in. Can a 3 speed be installed so that it could be shifted from the floor without alot of headaches. I kept the truck stock to avoid any cutting or mods that couldn't be put back to stock. I have access to a 60 truck and can pretty much do what ever I like. Thanks as always for your input.
