I know around this area one of the front runners is Chris Evans...procharged sbf, actually theres quite a few running that combo, fox body mustang of course. But then theres also Ron Rhodes who has run in the 4s with a small block on Nos with a first gen Camaro on Nos and hes only running 23* heads and leaf springs at that. Main thing is its gonna take alot of testing to get it right and dealing with varying track conditions as the tires are tempermental
