Ford Six Cylinder Engine Ideas!

Desperately trying to be different and keep the straight six in my 67 falcon... but i dont know anything about the six cylinder engines i have been doing my research on it. I want a street car with about 280-350hp and a decent amount of torque. I want to know if all the money i put in this engine will be worth it (6-month weekend project).

If I just had to keep the six and wanted that much hp, I'd be doin' research on building a turbo system.

Hi,
I agree with T Inspector, that little engine will need a lot of help
to get it where you want it, around 2HP per CI.

Good rebuild with forged pistons, smooth the casting on as much as you can (intake, ports, exhaust, etc) (use 80grit cartridge rolls), run a turbo kit with a "big 16G" or a good t3/t4 turbo (older designs but very effective up to 350hp), intercooler, and multipoint EFI controlled by megasquirt. If you do all the work yourself you're looking at 3-4 grand. And If you worked on it every saturday for 8 hours you could have it easily done for a late July cruise night.

I learned a long time ago that you don't need to smooth anything if you're runnin' forced induction. You just turn up the boost.

won't take very much to get it to 280 HP, but really, it could have 250 hp and you would still have more power than you expect because the little 6's can and will crank over 300 ft/lbs of torque when there turbocharged...

to get to the HP you want more easilly, 1 of these cylinder heads will be a big help.. then you can run a basic turbo setup.. no need for EFI, a holley carb modded for blowthru will do just fine.. get a clay smith cam that'll work good with boost.. yea, you'll want a good garret turbo and a decent intercooler, but in the end, 280 HP, and even 350 HP is well within reach with the alloy head..

sign onto www.fordsix.com and PM does10s.. he built his wifes turbocharged 250 CI ford Falcon, that has broke into the mid 10's

It gets so damn hot under there though!

I never run anything as cast any more, even a little old 80grit can help smooth turns and bring it all together, and its so easy. All its takes is a little time, and yes its honestly only going to make you need maybe 1psi less of boost, but hey, that's 1 psi. Everything is cleaner when you take it apart too, and at some point it will need to come apart for some reason- it always does.

Water injection would be nice as well, but really not needed if you run a decent intercooler for 350hp with either of the style of turbos mentioned.

Put a 300 truck engine in it with it's transmission and hunt down a Mustang V8 rear end of that era which will bolt in. The Falcon engine in all its variations isn't a very physically strong engine. While it can be hopped up to the power levels your thinking about, keeping it together is a really big pain the wallet.

Give some consideration to gooder brakes and suspension, again Mustang parts from the era bolt in.

Excellent advice! Source mustangs for parts. Even the stuff from later year mustangs could be made to work if you plan it out accordingly.

Ford 300 6 won't fit without firewall modifications.. it's a tight fit in the '69/'70 Mustangs..

the 144-200's are just as strong as a 300, there just not as big. some engines produce over 400 HP, without any problems with the block as far as strength is concerned

I've built a few of these things over the decades and have never been happy with the result. Never been able to keep a bottom end in 'em nor hold the head down. Fully modified they'll scream for a while and then bang, well actually they begin to hammer the mains well before they toss parts, so if you're paying attention you can head off disaster. It's a lot of money just to be different, which is why most people just don't do that route. He can convert his Falcon to a V8 using all factory parts or aftermarket replacements for less money, having greater power and much better reliability for a lot less effort and cost. I love building things but hate maintaining them.

Change the radiator to a cross flow and mount it between the grill and radiator frame, gets around having to hammer the fire wall.

others are having pretty good sucess with the 200's and 250's.. crank the bost and they do have trouble with head gaskets, but kept at a resonable point, theres no trouble.. there also just over 350 LBS..


this setup in this car was good for 12 second passes ( stock headded turbo 250 I6/ '63 Falcon 2dr).. it has since gotten some major upgrades and has a best of 10.85.. does pop headgaskets ( lots of boost ) but it's the same engine as it was, just upgraded

A friend of mine found an aluminum head for his 200ci 6 that's in his '65 mustang. I believe its an Australian piece. Looks super mean in the car. Has pretty good size intake runners and the chamber looks very similar to the design RHS uses on their aluminum SBC heads. He's running right at 8.5:1 and I'd say is making around 275 at the wheels. He recently wiped out a couple rod bearings, so we are going through it again... This time with boost in mind.

Also check out Cliffords...got some very nice stuff for them.
