the problem I had with the HEI conversion was there was not enough room to drop the distributor (with the cap off) in due to the forward slope of the fire wall, I had to unbolt the transmission and jack up the rear of the engine to gain the proper clearance, after the distributor was 3/4 of the way in there was plenty of room to lift it up to move the distributor around to get it properly timed.
