FLYWHEEL issues... HELP!!!!!

first of all if it is a stock bel housing, (check the numbers) im not totally sure but i think the 273 bells were cast iron,, it makes no difference if it is or not,, but if its a orignal 65 flywheel it will be a 9 1/2 inch clutch,,
all tho you can get new parts for that you cant get a disc for that for the tremec trans,,,

i have reserched this trany over and over,, and hope to install one next season,, i have already gotten a QUICK TIME BELL HOUSING for the smal l block mopar to ford tremec tranny,,,

keislier has a bell housing for a small block mopar to tremec tranny,,and it will fit your 273 all you need to do is buy a 10 1/2 inch fly wheel,,a stock one wil work or you can buy one from summit or jegs or mancini,,after market wil be around 300.00 last time i bought one,, a stock fly wheel; will be fine if you dont plan on drag racing at the track,,they may require a SFI approved flywheel,,,

dont buy a complete clutch pressure plate for a mopar,,you are going to have to use a pressure plate that fits the tremec tranny,, they are a 26 spline ,keislier hasa complete clutch,that wil work fine on the street, its a GM unit, the GM and FORD tremecs use the same disc,,im guessing the new chalenger will use the same 26 spline disc,, your mopar disck would be 23 spline,, that why you need to make sure you get the corect unit,,,
