SWFL Posted April 9, 2023 Report Share Posted April 9, 2023 Will an 18Z cross flow head engine and transmission bolt into a 620? How hard are basic parts to find for them? Quote Link to comment
Stoffregen Motorsports Posted April 9, 2023 Report Share Posted April 9, 2023 Z18? They are clocked to the other side, but with the right bellhousing, they will bolt in. I wouldn't wast my money though. The Z series cylinder heads were never great. I'd go KA instead. Quote Link to comment

I'm looking for a spare engine and trans setup. Will a non cross flow head, like a U67 bolt on the Z18 block? 1 Quote Link to comment
Stoffregen Motorsports Posted April 10, 2023 Report Share Posted April 10, 2023 Yes, it should. Obviously the front cover will be different, and there may or may not be a coolant passage in the head gasket that needs punching out. Depending on which gasket you use. For an 1800, I might try a closed chamber head. I bet the Z18 has dished pistons. Curious what rods are in the Z18. Quote Link to comment
SWFL Posted April 10, 2023 Author Report Share Posted April 10, 2023 Sounds hopeful. Do you know if the Z18 Transmission ( not sure if it's a 4 or 5 speed ) will bolt into a 620 with a 5 speed, without changing driveshafts? Quote Link to comment
