Coyote vs 363/408 fox at the drag strip??
I have owned and loved the heck out of racing my little 91 5 speed gt. basically a stock lower end with a good top end package, a shot of nitrous, gears, control arms, and it does pretty well at the eighth mile track I go to during the summer months for the small amount invested especially.
Of course, I want more, meaning either swapping to a 351w made into a 408, or a dart based 363. Since this will be quite a bit of money, I can't help but wonder how a coyote swapped fox would compare. I rode in a buddy's completely stock coyote motored 70 2wd short wheelbase F100, and was absolutely surprised on how hard it ran, especially being N/A, and through mustang manifolds.
I don't want to go the LSX based fox, but this coyote engine really has me thinking. What would be the outcome on a 363 based fox with a 100 shot of nitrous vs. a coyote with a similar shot? This is based on the average 363/408 build with good heads, matching cam, etc. in similar cars. I know the coyote would be smoother idling , and probably more street friendly, but I'm not too concerned, as long as the 363/408 could stay running, and not over-heat.
91 gt, stcock bottom, 11r190/fti cam/systemax
