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?

We used to run one in a SCCA Show Room Stock Camaro . The 350 TunePort was only available with an automatic transmission . Most of the other guys ran 305HO , QuadraJet , engines with a 5 spd manual . Our advantage was using the torque of the engine , and never revved it over 4000 rpm . Got much better fuel economy than the 305 crowd . These were typically 12 or 24 hour races , and you won if you had the most laps .

1989 was the first year with no "9th injector".
