300 ford..ported 240 head..just found out it has 7-1 compression..ran 14.02 in my 62 falcon...1.83 60ft time...motor is at machine shop getting balanced and new dome top pistons to get compression up to 11.5-1..any questions p.m me

If thats a street car that is very respectable.there was a maverick at our old track,early 80s? Morris and Hovie or something like that,a 300 in a maverick,was a joy to watch.

Circa 1976. Orange County Dragway. '61 Falcon coupe ("Humpin' Henry"). 300 six, Clifford manifold/header (custom), Roush "Cleveland" head (351C heads carved up and welded back together for a 6). 10.60s over 125.

That six has had more "goodies" made for it and won more races than any other straight-6 I know of. Remarkable performance potential, surpassing the Chevy and Dodge offerings of the era.

Don't discount Clifford Per4fromance. While much of their stuff is "dated", it still WORKS!

Cool idea, the 6.

I'm curious how the CR ended up so low w/a 240 head on the 300? Was it set up to run boost maybe (dished pistons)?

Anyway, good ET all things considered!

I read an article back in the 70s about cutting up a set of cleveland heads and furnace brazing them back together.I would hope by now someone just made new castings from Al. I doubt enough racers would buy the heads though,probably not worth it with all the better technology available now. BMW still uses an inline 6.
what ever happened to the GM over head cam 6 offered 10 years ago?

using a 240 piston on a 300 crank with a 6.209 rod and a flat top gives it 7.5-1..depending on cc of head, i have not had them cc yet, but they do have 1.94 or 2.02 intake valves, g-pa ported the head years ago, i just bought some 351w pistons with a 5 cc dome, that will put it between 11.5--12 to 1

first time out i had a lot of issues, shifter is a pos..way to big 800 Holley, then found that the throttle was only about 3/4 open, cause the pedal bent...and radiator was to small so it got to warm for me, all these bug have been fixed, it will run mid 12s next time out, tranny is a built rollerized c4 with brake..9 inch with 4.56 gears, .560 lift solid cam and crane 1.6 roller rockers..just got a 650 proform carb

[vinniekq2]

Nice car,My friend rory McNeil had a 63 with a 390fe in it.Love that era of styling.

[john-dickjr]

ups says my pistons will be here tomorrow, then to machine shop to get balanced..changed carbs to a proform 650, fixed throttle cable..just wish i know the rpm range of cam..has 560 lift and is solid i all i know

[vinniekq2]

whats the part number?Maybe someone here has a catalogue? Are the 6 cylinder ford rockers 1.7 ratio?

numbers on cam is 28-5-106 lc..so i guess its a 106 lobe center..then has a 785..the 560 lift is with a 1.6 rocker, actually it has 1.6 intakes and 1.7 ex rockers on it..
