Big block and TREMEC trans

I have that combo in my 68 Barracuda. I used a Lakewood bellhousing and (due to 2" chassis headers) a hydraulic clutch. I only had minor grinding to do on the rear X-member. The hump will need to be cut out for the shifter and an area just forward of the shifter where the trans case rises. The driveshaft has a 1330 front joint and 7290 rear and mine was fabricated by Keisler Engineering. I bought mine as a kit from Keisler so most all of the guess work was taken out. I`ve got to say it transformed the car into something like I`ve never known. The best mod ever! I`m running the .64 final drive with a 3.91 gear and can still cruise the highway at 70 mph at only 2200 rpm.
