Where should I start?

My knickle's worth is spelled SUPERCHARGED
You get to keep the 3.23s,
and no need for an overdrive.
Your engine already has the right compression ratio.
You will have so much torque, you may get to keep the current TC.
You get to keep all the current suspension pieces.
If you go turbo,you get to ditch half your exhaust system.Well that's not really fair cuz the new one will need to be bigger,lol.
What you end up with is a car that operates exactly like the one you have now, except it's a tractor around town, and a screaming jet-engine when you open it up.
And it won't cost you $12,000 to go low 12s.
Make sure your brakes are up to the task, cuz things are gonna happen dramatically faster.You might as well put 5-point harnesses in too.
And if you put 3 other um mature fellows in the car,It will hardly slow the car down at all around town. Just try that with your NA-360.
Adding 600 pounds of humans to your NA-360 will make it seem that she just lost her secondaries, and more. But worse is taking off with that 2000/2200 stock TC. It will feel like a loaded grain truck on soft black dirt.
The turbo car? Hah! A lil more throttle and look out! The boys will be giggling like little school-girls.
As for me, I would put a little lever or easy-button somewhere, and I would put a lil label on it that read "Maximum-overdrive", or "hemi-power", or "after-burners". Yeah, I like that last one.
This would be the boost control bypass.
We know the stock 360 parts can be taken 400/450 hp, and last for many years. So to take your 250hp to 450 is just a matter of bolting on the right sized turbo.
What you may not know, is that the NA 360 will give up some low-speed driveability, to make the power at the other end. NOT-SO the supercharged 360; it will start making power very early.Power that the NA 360 could never duplicate.And it will keep on making more and more, til either it blows up, or blows off, or you lift.Lift-off the gas that is.
Your biggest problem will be traction.
OK so; this is my dream. If I ever get a do-over chance, I'm going turbo. Turbo anything. Maybe even a turbo 273. I think a 273 could make 350hp easy enough, and I bet I could pull 30mpgs out of it on the hiway;point to point.Hyup, that's my dream.
Well I guess those skinny 273 rods would have to go.lol
