Pic #1 and #3 are a 92 block #2 and #4 are an 87
92 block is at least 2mm thicker everywhere so much better and don't seem to suffer the deck cracks like the early blocks.
Top pic 7M bottom 6M
I run an electric waterpump as a booster.
Either pump will flow through the other depending on which is faster so it's not restrictive.
I have the MoTeC controlling it but Davies Craig do a full PWM controller.
