MARCH MADNESS is where The Greg takes on a massive truck project or a series of projects. Here's a taste of what he plans on doing next month.

1. Engine Performance Top End Swap

2. Overdrive Manual Transmission Swap

3. Flowmaster 40 Series Exhaust Upgrade

4. Fix / Eliminate Massive Oil Leak

5. Relocated Alternator To Mid Engine

6. Rusty Radiator Support Swap

Thanks, she's happy below 3,000 RPM but anything over that and it seems she's racing instead cruisin' if you know what I mean, its just the justification I need to install that overdrive trans-a-mission

decided to get some Miles Per Gallon estimated before I tore her all apart, the last time I tried this my speedometer died, LOL

so we started with 26.4 miles and filled her up

then we drove 100 miles (second pic, speedo reading 126.4) and we had to add 8.263 gallons to fill her back up (at the same gas station, using the same pump, payed with the same debit card, wore the same underwear, etc. LOL)

so 100 miles divided by 8.263 gallons gives us 12.1 MPG, not bad

my goal and the magic number was 12.5 so that on a 16 gallon gas tank I could travel 200 miles, maybe with some carb tunning (I think she's running a little rich) and or hypermiling Prius Style we could have gotten those numbers

dang was that gas really under $2.00 bucks per gallon !!! USA USA USA

alright it's finally March and the weather is perfect, 72*F and so March Madness officially begins today, aka The Journey of a 1,000 steps

hey remind us again what it is we is doing

ok, for starters we are removing the engine and transmission

but first we get organized, since it may be a while before we go putting things back where we think they came from

so I cover the newly built work bench with 4 mil clear painters drop cloth, and I setup 7 clear plastic tubs for take off parts, like so, you get the idea

also have some blue tape and a Sharpie for labeling

and some before pictures of the rusty radiator core support

I'm thinking of painting it green, the color of the car instead of black, what do you all think?

I think when I made a list of things to disconnect, remove, unhook, loosen, in order to hoist the engine and transmission out I counted 26 steps before I ran out of room on the piece of paper, lol

first we drain the fluids, so the oil and coolant come out, I think I may leave the transmission fluid in that transmission since it won't be going back in and I won't be mocking with it any

I already can't wait till the day the fluids go back in!!!

then as always you start by disconnecting the battery, and since I will be removing the radiator core support, I am removing the battery all together

these pesky old heater hoses gave me a tough time, I decided they needed replacing so I pulled them off of the heater instead of the engine, one thing I learned the hard way is when dealing with old hoses, its better to take a razor blade and cut or notch them the long ways to get them off or risk breaking what ever inlet or outlet they are glued to

I swear they took me like 20 minutes, stubborn little rascals (that and a dull razor blade didn't help either, ha ha)

disconnect the upper and lower radiator hoses, I like to do it at the engine so it comes out cleaner with less junk hanging off of it

free up the carb by disconnecting the fuel supply line and the electric choke wire, you can remove the engine with the carb on it, but I like to remove it to prevent any damage to it

when I remove the spark plug wires I like to label them, it makes for a straight forward reinstall

also remove the spark plugs so they won't get hung up on the headers

Good job Greg! i remember motor removals and installs, except in old classic wooden boats. Just be glad you dont have wiring harnesses ontop of harnesses etc. etc. That makes it 10 times more of a headache
