not a ford man myself but my dad had a 70 mach 1 with a cleveland and a few upgrades that 340s wouldnt touch in the 70s. the runners in the heads are as big as rb runners. next time youre in a big machine shop take a look. the cleveland heads are impressive. ok now you can jump all over me.lol
YA YOUR RIGHT thay are impressive looking and thay do work BUT the heads start working at 7000 and the crank explods at 6500.. haha.them ford guys are somthing. but i will say thay do make some prtty good farm eqp.
