2F Block with 3F Dist.?

[tonkota]

Hi guys, I am replacing my 3F block with a 2F block. I am keeping the 3F head and EFI in my 62. Some thing that I don't know is if my distributer from the 3F will work in a 2F. Are they the same?

If not, what do I do? Can I use the 2F dist. ?

Also, I'm looking around Spokane WA for a 2F short block if you have one.

Thanks for any help.

fj60 or 2f dizzy and 3fe dizzy.....not the same. fj60 is vacuume advance, the 3fe is comoputer controlled. I don't know if you can use the 3fe dizzy in a 2f block.........but I "think" you can.

to use a 2f short block with the 3fe head and keep all the Efi stuff and PS and AC ect....you NEED a 79+ if not it won't have the holes in the block to mount the stuff......like AC, PS ect ect

Not to mention, domed vs. flat top pistons.

Which are domed? 2F? If I remember, the 3F pistons are flat .

Can I use the domed pistons? Are the pistons the same dimensions? I know that the bore is the same, but what about the wrist pin?

The early 2F's have the domed pistons. Through '79 or '80, IIRC.

2F and 3F bore/pistons are the same, so you're fine there.

I *think* that the only real difference between the two is the crank/rods. You might even look at putting the 2F crank into the 3F block.

Edit: There are a few minor external differences, though...motor mounts, stuff like that...

That would require custom pistons or rods. Not really worth it. The 2F block is about 2" taller. distributor should fit into the 2F
