Thread: Model A motor mounts question

Tweet

LAY N LO, I have a Brookville Model-A frame with several TCI components. The distance from the center of the left front rad hole to the center of the motor mount bolt is 13 1/2" and the SBC 350 is in the frame with a 700R4 trans which does match up with the holes on the trans mount. I do not have a body yet and I also have two worries: 1) Will the HEI distributor clear the firewall even with an indentation? For instance, the guy at Rod & Race told me their '29 firewall would NOT clear the HEI cap and I would have to use a points distributor. Other body mfgrs. hopefully have allowed a "dent" for the HEI cap with the coil in it and 2) locating the brake mount for a power brake in that the distance from the brake pedal pivot to the front rad hole may be off by 1/2" from the TCI instructions and even then I had to notch the crossmember by 1" to get the master cylinder on the power brake to fit. I will not know whether the brake pedal is right relative to the floor boards until I mount the body. At present my brake pivot is welded in (for the second time, after cutting out the first weld and grinding the frame smooth) at 41 1/2". The guy at Bebops says that is OK, but you need to check the position of the brake pedal pivot if you add a power brake unit. The tech person at Brookville told me that I did not order a frame for a Power brake, but that if I had they would hve milled a nice notch in the cross member for the master cylinder. The notch I have is not as neat as a milled cut but not too bad and will not be seen except underneath. Good Luck.
