Coyotes only! Well that sux! And to boot...fuel specified is vp101!!! Not 100% sure about engine build rules, but 101octane in an engine designed for 87octane is not good. 87octane burns cleaner, faster, and hotter and to an engine with an ability to resist any amout of detonation on the so called crap gas, higher octain is counter intuitive. This will be interesting for sure!Also reading through the article, ive learn John Kasse along with his Ford builds makes a statement!! Each time ol boy beats the pants off the others, the next year rules eliminate the engine type John won with. Just in case you guys dont see what I see, John wins builds with engines that were produced stock with very long connecting rods. Henry Ford learned very quick a very long connecting rod sustains stable combustion easier(answers why the ModelT engine were VERY long rods)..or you can say octain tolerance is much better. Fuel dosent like to be squeezed in confined space and to that 100billion lightyears of speed squeezing from a short rod piston a few degrees BTDC. A long rod will slow more rampant BTDC squeezing fuel slowly. A 5.4l rod is longer than any stock v8 engine built[emoji6]</blockquote>
