Have not looked into this for a long time but KB Inc were going to do a GM block also. Hemi Blocks are here not sure of all the variables being cast. Once things settle down on the Hemi Blocks other blocks were going to be looked at and Produced. I will talk to Tim when we are in Bewdley Ontario at his shop. He has to do the lifter bores on two of the blocks and after that we will drive the 30 minutes to pick them up. It has been a long wait for Raise Cam Hemi Blocks, just over 18 months but others might have waited longer for theirs to be cast.
