ZR1 uses a 6.2L LS series engine, with pushrods, just like the 7.0L Z06 engine. Same engine family, different displacement.
They've been saying the pushrod engines are obsolete(oudated and inferior mean the same thing as obsolete), but we still see them, delivering comparable or sometimes superior performance as the so called new stuff.
thanks....i didn't know what engine was in them.
for the guys that think overhead cams are new tech.....they're not. neither are disc brakes, superchargers, turbos, rack and pinion steering, hidden headlights.....it's ALL been around since the 30's i think.
and with performance....simple is best....and most reliable.
ever seen a smallblock chevy blow a head gasket? yet ya see 4 cylinders pop em all the time....same with the flat 6's i think.
