first, gas mileage, james cobra went 10.80's on a COMPLETELY stock LONG block, 2 1/2 in exhaust and still got 22 mpg with his t-45
i would take a DOHC motor anyday over my 5.0.
one of our customers 305's made 408 rwhp and like 375 tq
andy's 324 450+ hp and 400 tq
shitty things. stock rods and pistons suck balls. run heads studs and blew a head gasket, motor has to come out, doing cam swap, it's easier to pull the motor to do it. it's hard to even get the valve covers off
but the 5.0's do sound a hell of a lot better
