NASCAR 302 or 351? Things that make me go hmmmm...

PGkelly The Dodge is running the 360 right now, Ford is running the 351, and Chevy is running the 350. Is Pontiac still in the mix? If they are, they are also running a 350. None of the motors being used is under 350cid, sorry but the 327cid maximum is totally false. Also they most certainly do not run 9000rpm's on the high speed oval's. The restrictor plates limit them to about 7800rpm for max power, or at least they did last year. Anyway, this if comparing the two engines on a high speed oval, not an event which doesn't require restrictors, the 351 would beat the 302 in that event due to the increased, wait, no it might not, the 302 has spun up to 11,500rpms at F1 series level, the 351 would never hit greater than 9500rpm at a NASCAR event, which would allow the 302 to have a maximum potential greater than the 351? In fact, I'd say the 302 may outperform the 351 in all races. Hmmmm...

mustangII460 So they are still running canted valves? Interesting, I thought they were running straight up Windsor motors. I don't think the Dodge or the Chevy has canted valves, which would seem to be a huge advantage to Ford in races that do not require the restrictor plates. That seems strange, even so, the Boss 302 had the same, actually better heads than the 351C's so it would wash out to still being 351 vs 302.
