I hope to start the engine swap on my 58 Apache soon so I recorded some performance runs with a GTECH Pro. This will give me something to compare after the engine swap and supercharger installation. I made several 0 to 60 and 1/4 mile runs and averaged them. As it turns out the 0 to 60 and 1/4 mile times were almost the same.

0 to 60 avg = 21.88 seconds
1/4 mile avg = 22.10 @ 63.3 MPH

Since I know the weight of the truck (4160 lbs.) I used an online horsepower calculator to estimate the rear wheel horsepower. Using the trap speed method it came out to 82.3 horsepower. Using the elapsed time method it was 76.2 horsepower for an average of 79.25.

Then I used another online calculator for rear wheel to flywheel horsepower which came out at 101 horsepower. My service manual says the brake horsepower is 145. I know that manufacturers used gross instead of net numbers in 1958, but that seems like a lot of difference to me. However, since my power numbers are all calculated instead of measured it is really hard to compare them. Besides it really doesn't matter since I just wanted something to compare later.

I wish I had thought about doing this before I put the fuel injection and dual exhaust on the truck. From a seat of the pants perspective I know the truck runs much better than it did with the stock induction and exhaust, so it must have been really anemic before. When I bought the truck the drivetrain appeared to be all original so I assume all the internals are stock.

Please excuse the white tape on the radiator hose. It is an experiment.

inquiring minds need to know...why do you have dice in your sediment bowl?

100hp through aged internals may not be that bad. i can't imagine efficiency was real high from the factory in the manner of drivetrain power loss in that era.

It is little known speed secret so please keep it to yourself, besides I am the "DICEMAN".

You are right about the HP, plus I didn't factor in that I live in a high desert with a bad density altitude. I know when I have taken cars to Dallas to drag race they are usually about a half second faster.

Diceman, Your truck is so cool in so many ways and I enjoyed your description / analysis of the trucks power. Especially the zero to sixty and quarter mile times are about the same.

I have to ask, what is the experiment with the white tape? Speed secret?

Thanks for your kind words A/D

I am testing a product called "Rescue Tape" that you might have seen advertised on TV. (http://www.rescuetape.com/) I do a tech talk (aka Diceman's crap) at our monthly car club meeting and I am planning to do one on emergency repair items to carry in your vintage car or truck. Or your new car as far as that goes.

Rescue Tape claims, among other things that you can repair a damaged radiator hose with it. Since I am going to swap the engine soon and will be replacing all the hoses I decided to sacrifice that one for the test. I drilled a 1/4" hole in it and then taped it up. So far I have put about 15-20 miles on it and it is holding fine.

[diceman50]

So it begins.



I started the swap on my truck yesterday and as I was stripping the top of the engine I realized that I have never installed a 6 cylinder engine in anything before. I have removed several, but never installed one. This got me to thinking about how to put a chain or sling on the engine to safely remove the old engine and install the new one. In the past I wasn't too concerned about the old engine since I wasn't planning to reuse it and the replacement was going to be a V8. V8's have plenty of places to fasten a chain or sling to.

The drivers side of a 235/261 is no problem but the passenger side has no large bolt holes near the front or rear of the engine. My solution was to build a fixture to bolt on where the intake and exhaust manifolds go. Like most of my projects it is probably overkill, but I enjoy doing them.

Very cool project and I like the detail of your new engine.

Thanks for the tape explanation and it will be interesting to see how that comes out. Dice, I was showing my wife your truck and she read about your explanation on engine installation. She said, "wow, he is really creative." She asked me if I would have come up with that. Nope, probably not.

Elegant solution.

[diceman50]

Thanks again A/D

I have been reading about your 1948 Burb build. You too have some talent my friend! I can machine or fab about anything you need, but my paint and body skills are lacking. I am really envious of you guys that have that ability.

Thanks to you too Youngrodder.

[OutlawDrifter]

Very cool, building new tools and fixtures is very rewarding!

[ChuckDriver]

It's going to look awesome installed!

Thanks, it is rewarding. I love it.

Here is another one I built a couple of years ago.

[RockinKees]

Always handy, making your own tools!

Love to see the engine in its final place, I think it will look pretty cool!!

[Advanced Design]

Diceman, thanks for your generous comment about my skill. I appreciate that and I still have so much to learn.

Now that is a handy transmission installation tool!

[diceman50]

I wish these old trucks could talk. This is the bolt from the drivers side rear motor mount. I would love to know what caused that.
