I wound up getting a 22r for cheap, figured I could put my efi on and drop it in, turns out it had an 81 or 82 head on it, so it didn't have the correct holes to mount the intake.



My first attempt was a bracket going across a ouple bolt holes, didn't work, started sucking air when warm.

did alot of research, and 99.9% of it came up to change the head, definitely don't want to do that.
came across this
and i figure I can do that.

soo, went to industrial and found a piece of 1/2"x6"x18" for $18 and traced the gasket


started drilling




cut to size on my table saw with a carbide blade
drilled bolt holes, tapped the ones that needed to be tapped, countersunk 3 holes




got a bit for porting cyl heads to open up the intake holes


mounted


assembled




had to lengthen the intake support bar


haven't driven it yet, but no intake leaks yet, and every bolt hole is being used.

total ~ $30 with gaskets.

Looks good man. I didn't even know the carb'd heads were different :homer:

Extending the intake runner will slightly change your power
curve... I'm sure 1/2" won't be noticeable though...

from my research, the only ones that were different were 1981 and 1982, 1983 and up had both sets of holes for carb or efi intake.

Sweet. Why didn't I think of something like that? When ya gonna get a yeller star, so you can sell that to the guys who would think of fuel injecting a gen 1 carb engine? There might be a market for something like that.

Mine is an 84, and I had the same problem. Who knows though, the PO could have very easily swapped something else in...wasn't a 20R head on a 22R a "performance" upgrade? I'm not sure but my 84 pickup head most certainly was the old style. Cool solution, is it working yet? I am assuming you used two gaskets then?

no yellow star, no selling. this is to fix a 25 yr old problem, it's easy enough, and no demand. I just posted because I searched and searched and couldn't find nothing.
