SA engine in a FB
I am looking to have an engine (I think from a 79) as a back up in a racecar. I would like to have it for the most part ready to drop in if my current one dies. I have an 85 which is gutted and stripped of everything that I dont need. I currently have a bad 12a that I can pull parts from to install on the 79 . I am running a stock stripped intake with a modified Nikki carb.
It looks like there are two ways to do the swap.
1) Switch to a lightened flywheel to be able to use the same 85 clutch/pressure plate. I would still use 79 front and rear counter weights.
2) Stick with the 79 engine as is and buy a 79 clutch to bolt up to the 85 Trans (this is what I am panning on doing)
Questions:
-Will the 79 engine bolt up to the 85 trans?
-Will the 85 front cover, water pump, and oil pump bolt up to the 79 and can I now use the distributor from the 85?
-Are the oil pan and oil pickup swappable?
It looks like the 79 and 85 intake ports are the same

2. the pan and pickup and pickup are interchangeable and identical.
3. both are 4 port 12A's.

Done it a couple times. The only difference between an SA and an FB engine is the emissions control layout and the changes in emissions port location/function. In a non emissions application, they're interchangeable.
You're on the right track with the clutch.

I've got a 6 port 13B and a 4 port 12A engine that I swap back and forth in my SA22.
I think the motor mounts are different between the two, but I just keep the clutches and motor mounts with their respective engine.
I do have seperate carbs for both the 12A and 13B and I don't have any emmissions for either.
I also have seperate headers and catback systems for both....
I guess it would help if I knew the origins of the mysterious 13B engine. haha
