| Re: 88 IROC gotta go Yes it is a T-top car. As far as the engine goes, the only refreshed parts are the block and heads. It is a four bolt main, 9-1 compression, complete roller valvetrain, GM performance cam with .510 lift. The plenum has been ported along with the heads. Ported MAF, 24lb injectors, new BBK throttle body, deep sump oil pan, high pressure and high volume oil pump. The car runs well, it is dialed in pretty good using the moates system. I am sure it can be tweaked some more if a dyno or wideband O2 was used, but it runs strong as is. Hope this helps. |
