Bought an engine on the west side of San Antonio yesterday, was told it was a 1987 or 1988 Z/28 350 TPI. When I get there it is a TPI engine but it was different in some ways, perimeter valve covers, no 9th injector, 1 piece rear main 638 block. Fifty dollars later they load it in my truck using a dog leash instead of a chain hung on an engine hoist. So does anybody know about the 86' TPI engines? It has 261 heads. 1986 was a year in transition for the SBC. I haven't pulled the intake yet but could the 638 block be a non-roller block? I have other 638s and they are two bolt main 350s, the 880s are four bolts. I did pull a valve cover and it was very clean like could have been rebuilt clean. Opinions? A pieced together engine?
