Too bad you don't like EFI, as those were the best years.
Try 85 or 86 might be ok, or 82 and earlier. Some mid 80s really loosened their exhaust manifolds possibly due to higher operating temps for emissions--not really sure. My 85 loosens the manifold too, but it seems like the 84s were the worst.
best setup would be 95-95 when they had MAF EFI. I wouldn't bother with late 80's unless you swap back to the dsII setup as the elctronic carb is a bitch
Also, in the '80s they used TFI ignition. Ditch that if you find it. It is prone to sudden failure, usually when you are in front of a train or on a drawbridge that is signaling to open.
It's not that I don't like the EFI, I thought it might be harder to install. The truck recieving the motor has a 351 V8
Consider this: You may find a roll, bad crash or partial burn low mile job with the efi motor. (someone's misfortune is your gain) Buy the whole thing and swap all the stuff. (easier said than done, I know). You may be able to find a rolling total in the want ads that some guy wants to unload.
Are you planning on doing any kind of rebuild on the 6 before you install?
BTW, if you are going with the 300 to save gas over the 351, think again....
Yes, I am planning on a total rebuild before installing. The EFI might be nice. I just bought a 89 crew cab that has a 351 with a 5 speed. the P/O installed the motor and trans. the truck originaly had a 460/auto I have never had good luck with any V8 and the I6 seem to run for ever (IMO). the truck will be used for work.
Get a 300 HD or 240 block =). If you can find a '60's motor that hasn't been bored or trashed, it would be better, they were thickwall designed and were able to be bored out .060 over with no problems. I got a 247 now =)
