Ford 300 inline 6 with 240 cylinder head sound

Here is a sound clip of my beater F-100 after installing a few cheap parts to wake it up a bit. Engine is a stock 1968 300 .030 over, with a 240 Ford cylinder head for increased compression, Chevrolet 292 rocker arms for more lift, EFI dual manifolds into Walker Y-pipe connected to 2.5" Red Hots glasspack, rejetted stock Autolite 1bbl carb, and stock points distributor converted to electronic via a Pertronix Ignitor. Truck is an F-100 long bed, trans is a worn out T-18 4-speed, with 3.50 rear gears, and 235/75/15 tires. Truck runs 18.5 @ 75 in the 1/4 mile at 2300ft DA.

check out the holley mech secondary 450cfm, cant beat it for $250, summit says its for dual carb applications but its perfect for big sixes, i knew a guy that ran one on a 4.3 chevy and it ran bitchen, was planning on running one myself until I scrapped my 300 build

summit p/n is HLY-0-9776

@dezertdisasters I used one of those on a built Chevy 250 I had, and it worked great! I am going to go with a 500cfm Edelbrock Thunder AVS on a Clifford intake manifold as my next upgrade. Also will replace EFI manifolds with either Hooker or Clifford 1 5/8" tube headers, and install a mild cam at that time. Will post a video after the upgrades are done!

how much does the 240 head cost?

[SRCAfan]

@kargmeister1337 I got lucky and found a new Ford head in a crate on ebay for $300 shipped. I'd say if you find one it really depends on where you find it and what condition it's in.

So how does the 240 head do for performence on the 300? i've been thinking about doing this to a 300.

[SRCAfan]

@dirteeter32 The head upgrade made a big difference! I have picked up about 2 MPG, and the truck has a lot more power then it used to. The 1bbl Autolite carb has to go though. My next step is a Clifford intake with a 500cfm Edelbrock carb, and an Isky 262 Supercam. Check my other video of the truck accelerating to get an idea.......

@SRCAfan did the head throw off your ign timing? are you still running normal vac. advance?

[MrTpengineer]

god look at that truck rock! so much tourque for that engine :)

[StickPeopleAndPuff]

i know this is a dumb question, but can a 250 inline run a 240 head or is it too big?

Where did you get your air cleaner?

[ClayPigeonKiller]

@amurican35 300 is the cubic inch displacement of this particular engine. There was also a shorter stroked version that came out to 240 cubic inch. Both built by FORD. Prices vary, many need rebuilt.

300s were used more. 240s stopped production in the later 70s i think. The 240 and 300 had the same block. Rotating assemblys are different. Combustion chamber in 240 heads is smaller, yielding approx. .5 increase in compression when used on a 300.

What's the "240" in the "240 cylinder head" a about . Who makes it ?

[evilperson86u]

Go with a chambered muffler like flow-master if you want it to sound good. Makes it Echo thus makes better sound.
