<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: markjohnson</div><div class="ubbcode-body">I think the most important aspect of '68-'69 L-88 Corvettes being dominant in Pure Stock is the massive amount of engine setback which is a major factor in a class with such tire limitations. It's obvious that a 12.5 Compression, massive solid lifter camshaft, factory 850 double pumper on an aluminum headed 427 CID might be a small factor also! Superior exhaust manifolds also compared to Camaros, Chevelles, etc. Chevrolet started the Cowl Induction theory with the '63 Z-11 Impala and even Smokey Yunick said that during testing, a Cowl Plenum air cleaner was good for approximately 1.00 PSI at speed. When this Pure Stock way of racing took off several years ago, it was obvious that as soon as someone properly prepared an L-88 Corvette, that it would be over for everything else. </div></div>

You mean the biggest carb GM ever used, highest compression ratio, Best intake, Biggest solid cam ,best GM ex. manifolds, a 50-50 weight bias, best aero package, big tires. Might be an advantage over other cars ??? [img]<<GRAEMLIN_URL>>/dunno.gif[/img] Hahaha
