If your interested there are several threads on the HAMB board under the banger threads about installing the S-10 T-5's in model A's, crazydaddyo built the parts for his and there is some great tech he shared.
when I got my first A motor an old timer told me that you were supposed to check the oil with the stick out of the block, trust me you dont want to do this, it took me about 30 seconds to figure out that this wasnt right, allot of windage.
