On big reason is the use of hydraulic roller lifters starting in 1987 and a boost in compression (atleast for the Caprice 9c1 350-cid). This bumped the HP on all motors (HP on Caprice 350 jumped 25HP to 180HP).

Re: Big question!
HLandin nails it. The '84 had an 8.5 c/r and the '88 a 9.3 c/r. Along with hydraulic roller lifters, which were good for a 5-hp boost alone.
