I do not see why timing for a 153 or 181 would be different. The cranks and cams can interchange with a bit of fuel pump lobe interference. Rods are the same length. How different can they be? The stock HEI is good for more rpm than anyone but an all out racer would use, and few of them would actually get there.
one would think so, and maybe it is, but the same family of engines, only the 6 cylinder versions have different "All In" specs on the timing, and im about tired of all the experimenting that ive been doing, so I was hoping someone would have the specs so I would know for sure if the distributors can be swapped without the need for sending it out to a distributor shop to be worked over...
