Between a 1970 and 1972 motor, which one would be the one to keep? o No: If I don't sell one of these suckers soon, one of them is going to the scrap for gas money and to clean out the garage. :dollar: Wayne S
If it were me, I would keep the 1970 engine, just simply for the fact it's a higher performance engine since it has the higher compression ratio, if I recall correctly! Neither of those engines are bad, the '72 is nice too, and can be souped up just as the '70 could, but if you keep the '70, you will already have the higher comp. pistons so it'll be a better start to a performance engine. I am not aware that the '72 would have any major advantages over the 1970, but maybe someone else will chime in and give you the whole layout.
the 72 heads might have the scallops in the heads,the 70 heads can be used on most any year block since no scallops 70 might also have an N crank which is alittle stronger other than that both engines are pretty much equal
The 1971 and 1972 engines were built to run on No-Lead or Low Lead gas... something to think about.:idea2:
My '70 350 was meant to run on leaded gasoline I suppose but it hasn't seen leaded gas since it was new. Still runnin, good and strong....not even so much as lead additives...
