If I switch to HEI are there any clearance problems? I know there is room once installed but, on my BB when putting in the points dist the rotor had to be removed to squeek it in.

HEI is taller and wider. No clearance problems on a SBC installed in the correct V8 position, but i dunno about big-blocks....

NO CLEARANCE PROBLEMS AT ALL. SMALLBLOCKS IN THE 6 CYL. POSITION WILL CLEAR THE FIREWALL JUST FINE, ALTHOUGH YOU DO HAVE TO REMOVE THE CAP FIRST. BIG BLOCKS IN THE V-8 POSITION & ALL MOTORS IN 4WDs FIT GREAT TOO. JOHN
