I have searched and can not believe there is no info on the 5 speed, behind a flatty.????? did I look in all the wrong places.?? prefer not to go and get a store bought adapter, but will if needed.. I once had a Buick nailhead and just got my machinist to redrill bolt pattern and center hole, and Chevy 5 speed, fit right on... any ideas.? thanks, Lloyd
Lloyd , I have seen many use the 5 speed behind their flatheads before and lots at shows all the time . You can check with Trans Dapt to see if they have a adapter for the trans . I have seen some that make them but can't remember where . I was going to build a flathead I had and put a T-5 behind it but changed my mind on the engine since I could get the HP I wanted from the engine . You can also try Flatheads Forever and see what they can tell you . I will have to check through all my folders and see what I can find for you . Jim
Lloyd , Here is a great link that will tell you all about the different transmissions and the adapter for flatheads down near the bottom of the page with where to get them ! Good Luck and let us know how you make out ! Jim http://www.flatheadv8.org/ernie/ernie-t5.htm http://www.wilcap.com/flathead.html Also many use the T5 from a GM too . Here are some links for the adapter for a GM T5 trans . http://www.google.com/search?source...gc.r_pw.&fp=eba5bab8455f1d6c&biw=1264&bih=522
Here is another option , Graeme is a buddy of mine , he regularly ships stuff to the USA . http://www.macsspeed.com/adapters_2.html .
This discussion has been explored from end to end many times on this and other forums. The T5 is perhaps the best thing you can do for a flathead! HOWEVER, you must do your homework first! You need to factor in things like rear end ratio, shifter position, and T5 gear set. DON"T just drag home any old T5 from a junkyard and expect it to perform! If you plan carefully, you can install a T5 and use your stock pilot bearing (or bushing), your stock flywheel, your stock pressure plate, your stock throwout bearing, ALL of your stock clutch linkage, your stock bellhousing, and your stock rear transmission mount (slightly modified). You'll need to buy are a different clutch disk (maybe $50), and a different speedometer cable ($12). Your biggest expense will be having someone make you a simple flat-plate adapter to go between the bellhousing and the T5. You'll need a new driveshaft, too. I have lots of pictures of mine --- done as described above. Glad to share them.
