I have a 29 tudor thats going on a TCI chassis (straight axel,vega steer). I ordered the chassis with motor mounts, tranny mount installed.(SBC, 350 trans combo). Last night I placed a mock up motor and trans in the chassis. The motor is sitting to far back. My four inch recessed firewall would be sitting on the back edge of the distributor hole. After measuring rad,water pump, pully arrangement it looks like the motor could go ahead two inches. I,m wondering if this might be a big block set up? would anyone have a measurement from drivers side rad hole in crossmember to center of motor mount for SBC application. Thankyou.
