What psi boost could this engine safely handle?

This is the engine in my '82 project. I am planning on either a centrifugal supercharger or turbo installation. Rather than carb, I am running a large runner TPI setup.

How many pounds of boost would it be safe to add, and what size injectors should I run? I have a chance to pick up a good deal on a kit set for 12lbs and I wanted to make sure it wouldn't be too much for the engine to handle.

Just run it and pull timing and see if it detonates, if it does pull more timing.

Is this a MAF or MAP/SD TPI setup? 60lbs injectors will give you all the fueling you need.
 
The camshaft can be quite good for a supercharger (same duration intake and exhaust) and quite wide LSA (which helps with supercharger).
The compression is quite low....which is ok!

But Hypereutectic pistons and small 1.94" intake valves can be the very limit for this engine, like stock rods and crank (I assume are stock because aren't mentionned in the list).

To be very honest this long-block don't seems very "racey" and I will be very surprised to read 325 horses in the dyno with these heads!

But the 4 bolt block is a very good thing!!!!
