I told you a lie earlier. The 75-80 20r blocks and 81-84 22r block height were both 9.120". The 85+ 22r block height were like 8.something i cant remember the exact number so basically if you wanna do a hybrid. you basically have no choice but a pre 85 block. It seems like iv seen someone do one with a 85+ block though? maybe they just milled the head down alot?
ok, lets dial back on spitting out numbers hoss
the 22R block will bolt right in using the same transmission, starter, engine mounts, everything.
you want numbers?? the 20R and early 22R blocks had a deck height of 11.280 inches the 8-84 and newer 22R/RE/RTE all had deck heights of 11.080 inches.
the later 22RE blocks can NOT be used. well, anything could be done with the right skills and enough money but realistically 85 (August of 84 actually) AND NEWER BLOCKS WONT WORK FOR BUILDING A 20R/22R HYBRID
You definantly are helping! I've already learned alot. Do you know of any websites that might have the parts I would need to build the 20R head that way?
you dont need to put a lot of money into this. if you have it great if not dont worry. pulling your 20R head off your current block and clean it up, put new valve stem seals in it and sit it right down on a good 22R block and GO. its that simple. EVERYTHING can be from the 20R EXCEPT the pistons and the carb. a header will be of tremendous help
