rrcredline Posted June 3, 2010 Share Posted June 3, 2010 hi all, does anyone know if they engine mount bolt patterns on the blocks are the same between RB30 vs RB25 cheers BH Hello BH Yes they are. I have the press steel type, cast iron type RB20-25 and fabricated type RB30 and they are all the same bolt pattern to the block. I used the RB30s for no other reason than I wanted to.
