These things weren't built at all for speed.....

You can swap out lower gearing in your rear end though. Like 3.73 or 4.10's but kiss you good mpg goodbye...

There is someone on here or atleast used to be on here that had one in a maverick that ran a quarter mile in under 10 seconds. Your best bet would be the 300 forum on here.

The same things that apply to a V8 apply to the inline 6. 4V intake and carb, headers, camshaft, roller rockers, bump up the compression, do some head work.

If you want more info on building them stop by this site. Ford Six Performance Home/Index

If I had a 6 I'd turbocharge it be a hell of a motor.

Yeah there was a member here who did it. I was honestly damn impressed with the whole setup and the numbers he was getting. He did it for dang cheap. If I didn't have a 460 I would do just what he did.

Yea after you install ARP head studs, a good head gasket and some ARP rod bolts. I've seen many stock 300's with blown head gaskets.

And I personally think a Eaton M112 supercharger would be a better match to the 300. No lag just instant torque from the hit of the throttle. But it would require more fab work.

Horsepower costs money... how fast ya wanna go? As mentioned above: 4bbl carb and intake, mild cam, upgraded ignition, headers, a free flowing exhaust system, better gearing, a manual trans (if you don't already have one)... for around a $1000 you can double the factory horsepower and more than double the torque output of these engines. Not to mention they're bulletproof and can put up with tons of abuse.

My son asked me the same for his 2000 V6 Mustang. I swapped out the 7.5" open rearend with 3.25 gears for an 8.8" limited slip with 3.73 gears. It made a big difference in acceleration without touching the engine.
