TR 2100 Posted April 8, 2018 Report Share Posted April 8, 2018 (edited) Only difference I can think of is the TR4 breather hole in the block - this has a blanking plug for the TR4A. Need to be aware - BUT - same block casting. (Cylinder heads are different but interchangeable) AlanR Edited April 8, 2018 by TR 2100 Quote Link to post Share on other sites
