I have been for a long time. Taking clues from newer rigs, and old school simplicity, here's my idea:
-Standard 300 build with all stock internals, except hyper pistons at about 8.2-8.5:1. Maybe head & main studs, & ARP rod bolts.
-Late model EFI 4.9 intake with a little bigger & better injectors.
-EFI controller? Not sure, but Megasquirt seems like it would have to do. Run it for Mass air, not speed density. That, or custom reflashed Ford computer.
-Airesearch T04 turbo to bring some top end & towing fun to it.

 

Nearly completely off-topic question, except it's a six-cylinder thing...is that a 401 tractor engine in your avatar? That was made in Brazil, correct? Just thinking that would be cool in a light-duty truck, except for the weight.

It sure is, but it's the truck version. NewHolland 6.6/ 401. I was actually dead set on putting it in my 67. It's not but 100-150 pounds heavier than a Cummins 6bt. It's just really long, which is the main problem.

 

The basic build you laid out sounds rather reasonable to me, but you missed a simple trick. Tune it for E85. Cheapest 100+ octane fuel on the market, and you could either run higher static CR or higher boost......

 

Here's another little idea. EFI exhaust manifolds, and 2 small turbo's. Can you just imagine the torque that could be made with 12-15 PSI boost @ 2,000 RPM? Who cares if the turbo's run outta breathe @ 4500? No need to spin it much higher for the street......

 

Col Flashman's engine with a supercharger and still running a carb.

 

Col Flashman's engine has yet to be topped as the ultimate street 300 build. JMO

 

The ultimate 300?

Bore it 0.030'' over
block decked to 0 height
Offset ground crankshaft to stroke it
Line bore the main crank bearings
Balanced
Custom grind cam (HOT HOT HOT)
Roller lifters and rockers
Screw in studs and stiffer valve springs
LS1 heads welded together and custom intake and exhaust
4 barrel 600 cfm holley with an Eaton supercharger wth the appropriate compression to run it
Massive head porting and opened up to larger valves
9'' rear with 3.55 gears and a C6 transmission

... All of this sitting in a 64' or 65' Falcon or a 66 Fairlane.

Just my opinion.

Your motor sounds good too though.

 

I think that to qualify as 'the ultimate street build' money has to enter the considerations. Undoubtedly, his build is great. But, who wants to drop $5k on one of these engines? Most of the guys I hear from here are doing it themselves. Anyone can pay a shop to build one, so I think there should be two classifications: do-it-yourself, and shop built. Also, since we're talking 'street build,' I think we need to think about mpg vs. power, driveability, etc.

For pure power though, flashman's build has topped the charts.

 

Flashman also bought a brand new engine so you have to factor that in also. I think Flashman could have also gone a lot more crazy than he did, and gotten much more power out of that engine, but he wanted it to be more drivable.

 

Well...there are some qualifiers. Ultimate build with unlimited resources? Ultimate build with limited resources? Ultimate build DIY with +/- resources? And what exactly is an "ultimate build"? It's all pretty much subjective without definitions.

 

...bottom line: yes, I admit it, I'd love to have that engine.
