I have built a few 300s now and they are fun engines. There is a car called the Frenchtown Flyer that is a drag racer running a wildly built 300, it looks like he has some form of crossflow head on it now. I haven't followed his builds since about 2004, but it's still out there being wild.
Nothing beats the sound of a base-3 engine IMO, with sixes and twelves sounding the absolute best.
The first 300 I built was overdone, and could spin 35s on dry pavement, but was finicky and got bad mileage. There were a few stock ones in there, then I hit a really good combo before I went diesel- I used flat top 360 pistons and a Delta mid-range torque cam with straight up cam timing. It was in a van, and with a 2.75 rear gear and C6 auto I could run down the freeway at 80 and still get mid teens. I even did some limited towing with it, and it did well. That engine was bored out to 4.080" to fit .030 oversize 360 pistons (the machinist thought I was nuts), but it didn't overheat even in 90*+ summer heat.
I've thought about building another one like a tractor pull engine, just to see what they could take before the final limits of the block and crank, but that's a long ways out right yet.

That sounds like an interesting build, I've never had a 300 before so I'm thinking of keeping it, might just buy a big block and build it on a stand and down the road throw it in

I have the 300 big six in my 67 F100. The low end grunt is incredible, and it gets good mileage. I love how much room is under the hood, as that long, slim block doesn't stick out very wide. Plus, the big six is unique. Not everyone has one. I'm quirky like that.

I vote for a 300, but built up a bit. They sound real good with a cam. It can put a hurting on a 302. A 351C, built 400, or 460 would be other choices.

Horsepower on Spike TV built a 300 last season...I think it's worthwhile to review the episode: A Buildup of Ford's Classic Inline Six | Horsepower | PowerBlockTV - Full Episodes
