Pretty small turbo for 15psi on those cubes...20 forget it.....it will spool good...Is that a 76 GTS turbo rated for 1100, or is it like most 76's rated for 800-900 flywheel? The cam looks good. Actually, it looks like a rip off of a Virginia Speed grind...ICl is not listed but I bet it's somewhere in the 110 area....

When you put some timing in the right spot and get the mixtures correct...hell yeah, that will spool...probably out of breath by 6200rpm...
GTS 76 is T4 or T6 flange? A T6 would help on those cubes with back pressure...(especialy the cam selection your looking at). If your using t4 and depending on manifold choice then even a reverse split might be in order.....

That thing will be a torque monster.
When you max out the turbo, you just wont make anymore power. Keep in mind that it will make the charge very hot which leads to detonation and ultimately failure.
