This is'int a drag strip and those cars get rebuilt after almost every race.
The only reason pushrod engines are still around is because their cheaper to manufacture. And your "drag strip" pushrod engines might see 2-3 races and run fantastic but then there getting torn down for a full rebuild, Formula 1 engines run an entire season before being sent back to be rebuilt, all running OHC setups kicking 12k for hours not 6-7 seconds. Pushrod engines have proven what they can do, i understand that, but i still believe OHC designs are far superior. Cobra V8 is 32v OHC and look at what it can do, stout as fuck and accepts a .650+ lift
umm yeah spanky do some home work before opening your mouth. The motors at drag stips that get rebuilt after every run at 800 C.I. mountain motors that are designed after Dodge Hemi's. and they are running
100% PURE NITRO METHANE!!!!!!!! No engine will last long running nitro methane. And F1 motors yes, are over head cam, but they are built completly differently for a totally different purpouse. and they dont usually make a whole season with out being freshened up. they usually get gone through after every race.
and The 4 cam cobra's are nothing special. they need a supercharger to hit 400 HP where as z06 Vette's are at the same power platue naturally asperated. if pushrods were so bad why is one the fastest vehicles in america the ZR1 running pushrods reliably at 600+ hp? And look at c-5 and C-6 Vettes, you can drive around with the a/c blasting and get 24-27 miles to the gallon all day long!
Im not biased towards one manufaturer or another, but realistically the best bang for your buck and longevity without any question when dealing with V-8s is with an LS-1. sorry to rain on your paraid.
