Thread: 300 ford 6-cylinder head mod.

Tweet

anybody remember an articial in hot rod or car craft back in the early or mid 70's about installing cleveland heads on a 300 ford 6-cylinder engine???????

Going to be some very extensive mods to put Cleveland heads on a 6!!!!!

i seen one awhile back about taking sbc alluminum heads chopping them up welding back together made 1000 horse with a big oll turbo on a 250 chevy 6, in a studebaker.

Don't have any article ---but==it was done by cutting off one cylinder from two heads and putting the two 3 cylinder portions together--the straight 4 and 6 cyl engines got a better weight break in NHRA mod classes and the Cleveland head was the best out there---I seem to remember that they may of even been used on some Chevy or AMC blocks

jack roush did that with the iron boss head .someone told me maskins(DART) did them many moons ago they cut them up and furnaces welded them up
