If you do anything to the engine, compliment the rest of the power/drivetrain package with a quality/tweaked-to-your-combo torque converter and some deeper gears. It'll be a whole new car. My 318 wasn't very complicated and managed a 13.6...not too shabby. Get the engine where you will be comfortable with it, and tune the rest of the driveline to work together.

Good suggestions so far, except for the 440 talk, those guys must not have seen the part about the budget.
Anyway, changing the gears to 3;55 or 3:91, probably would help wake it up, but that's not happening. I'd say 90% of my driving is on the highway.
I live in a small town, and although driving around town with 3:91's would be fun, driving around town in Lyons takes about 5 minutes max.
It I want to go do something I either have to hit the highway for 15 miles to Boulder, or 12 miles to Longmont. I'm not going to do that with the engine screaming along at 3000rpm. So until I get an overdrive, steeper gears are out.

I drive mine 51 one way to the track. 90% hwy w/ a 3800 stall and 3.91's. Not a big deal 3k isn't screaming. I missed that part about altitude... I know you think Feets is crazy but a simple small turbo would give what you need w/ tearing the engine apart.

best bang for the buck will be a higher stall torque converter.
Cylinder pressures for this altitude are not too bad. Cam, intake, carb, exhaust are OK.
A set of the newer magnum type heads with smaller chambers will flow better and increase the compression ratio. Check Hughes Engines for the EQ (Iron Ram) heads for the LA engine block.

From an earlier post (I am sorry) I forgot who it was "At the very least I would stroke a fresh 318 to 390ci or so and put either 302 or 308 iron heads on it with a cam designed for your combo at that elevation. Or as others have said TURBO on a good healthy engine." There are several shops out there that have either a steel or a cast crank package with high compression pistons and good rods for $1200 to $1500  Leave the rest of the combo alone. I am planning that same deal for a truck 360 that already is .030 over for my D100. I may have to go lower on the compression because I live @ 600' (at the foot of Mt. Rainier) and you can get away with more. Good LUck

Keep the serpantine set up get a cheap in line fuel pump and it will walk all over your current combo. Your current combo is terrible. A piston swap only gets you more compression, magnum heads help power all around but you got to buy different PRs and the heads and still have a flat tappet cam. The best part is you can do it in a weekend VS how long will machining a block have you engine down? You don't even know you can just stick pistons in till you tear it down, the rings on the KB167 go higher up the bore.

I agree with a turbo setup,requires some fab work but well worth it and can stay under or at budget.
A magnum swap is a good direction,will need some work,computer work or induction/electronics,can stay around budget limit.
A pair of closed chambered heads,1.88/1.60 valves,some head work,thin head gaskets,convertor and gears,headers,advance the cam,it will stay under budget also.

I just replaced a mild LA 360 with a 408 magnum stroker. Kept the serpentine belt, performer rpm airgap, holley 3310. The power on tap is amazing, I couldn't be happier. Also, I had a 8.75 with 3.55 SG installed. And a year or two prior I had the trans rebuilt with low gear set, factory high stall converter, and transgo TF2 shift kit. I love the performance of the old pile of bolts.

What is the stall speed on the "factory high stall converter"?
And do you have a p/n, or where would I get one ?

I dont have a part#, I just had the builder order it. IIRC it was somewhere around 2200-2300 or so. But since its behind a much stronger motor it stalls higher than its rating. I havent played with the car enough to nail it down say its right around 26-2800 or so

A factory replacement "CR8H" is supposed to stall between 1900 and 2400 rpm according to the transtar catalog. I don't know the pricing, but I'd expect around $100?

If you need a higher stall then might have to go aftermarket or ask Transtar above. I got a heavy duty version (better sprag, I think roller?) of a factory high stall 727 converter and it was less than $200.

Also call Don over at Ajax Auto Parts in Arvada, 303.420.3696. Chances are he probably has a good used one for dirt cheap. Let him know I sent you.
