And the difference in the engine is the cams. Your 89 would have what's known as the peanut cam, complete junk. The 90-92 TPI cars all come with the L98 cam. The only way to get a good cam in the 87-89 305s was with the 5 spd and G92.

First its not 295 HP, its 195. 
The difference was the cam changes. The compression is all 9.3:1 for all years of 305 TPI, as far as I have seen. 89 MAF and 90-92 SD 305 TPI 5-speed with G92 is all rated at 230 HP, so the MAF -> SD switch gained nothing there. The 350's gained 5 HP from a piston change that increased compression about .5 points, from 9.3:1 to 9.75:1 or so.
