89 to 91 1/2 eng differances

ok getting all the parts ready to put the motor to geather I am going to use the 89 intake and fuel system and by a banks intercooler setup becouse the intake is melted on the 91.5. is there a large differance in power betwen the 89 pistions (more compresion) and the 91.5 pistions I can get buy with hot tanking the 91.5 and rering and bearing it. The 89 needs a sleeve. new set of pistion for 89 in the 91.5 block $280 or just stay with the 91.5 pistions? going to use the 91.5 head. the cam in the 91.5 is bad (Rust on lobe) is there any after market cams?? what injectors do you thank would work the best ? If anybodys sees anything wrong with this let me know thanks George
