I don't know block #s but the turbo blocks are the ones to have. I have a 87 TBird Turbo coupe with 142k on it and is as strong as the day it was new. They are great engines.

 

My youngest brother had one with about 140K on it. We re-seated the valves and put in new valve seals in my garage. That thing was *FAST*. If you plug the outlet/inlet on the MAP sensor, you can fool the turbo into overboosting, but you may have to walk home... I think you disconnect the rubber tubing.
I gapped his platinum tipped plugs before putting them back in. Hmm, what's this little hair like thing on the center electrode. It didn't start too well until he put in new plugs, but sure ran like a bat out of h*** after that. Used plastic milk carton to take up the slack in the horizontal shock absorber on the rear axle. Made quiet.
He sold it to the first person that looked at it. Nice off burgundy and red interior.

There is no difference between the turbo and non-turbo blocks save the oil drainback. Turbo blocks do have a different replacement part number due to the drainback but there is no difference in the metalurgy of the block. Now, Ford did make a tall deck 2.3L block in very limited quantities that did have some additional reinforcement around the mains to make the block good for 700+ hp.

I think you're probably referring to the boost control solenoid Tom. No 2.3 turbo motor has ever used a MAP sensor, only a BAP sensor.
