2.3 head on 2.6

Postby korbin22 » Tue May 15, 2018 11:09 pm

So I’m pretty sure I just bent a push rod. I was thinking I could just get a 2.6 block and use my 2.3 head since I just redid it less than a month ago. If I did this I heard performance is better and compression is high so I would have to use premium gas. So is this possible and if so what parts do I need to use from the 2.3 and what parts from the 2.6. I plan to stay carb and I have a Weber 38.

-2.3 distributor, intake, head, engine plate, flywheel & clutch, engine accessories & brackets
-2.6 short block & water pump & 2.6 water pump pulley (the 2.6 water pump is longer than the 2.3 pump, the 2.6 pulley has the correct offset to realign the belts)
-all the timing components from one engine or the other, do not mix
-transfer the clutch cable sheath stop bracket from the 2.3 to the 2.6 or fab a bracket if it won't bolt up
-the 2.3 oil pan may not clear the crank, if you swap to a 2.6 pan also use the 2.6 oil pickup & dipstick
-compare 2.6 & 2.3 motor mount part numbers, the existing 2.3 mounts should work
-'93-on 2.6 with the later piston design will have less compression boost than the earlier flatter top pistons, might not require premium fuel
-make sure your radiator is in top condition, use a 7-blade fan & shroud
