i've been building a 38 dodge pick up for the flats with two engine classes in mind . xo and xxo engine classes . no newer engine then 1959 . so early hemis are employed a 55 desoto 291 and a 56 chrysler 354 . both blown of course . these are full on racey motors than must survive , peddle to the metal for a few miles . i've a lined myself with some great guys , that now the salt flats ropes sort of speak . my desoto is a proven design and the chrysler is as well . but its an out of pocket deal . and parts can be costly . and not to mention hard to impossible to find . so costly tooling equipment is purchased for the builds . and on and on i go , lol . i ran a 37 dodge on the streets and it went 160mph , so there arrow enough . just looking at 200mph but biuilding for 250mph just in case , lol .
