Welcome to the "NANDO BUILD"!

From this first page onward the saga of one mans quest for Uber reliable power will unfold..

My good friend Nando (martinef1963 - club member here) has experienced engine power problems. He has made the decision to rebuild for two primary purposes:

1 - Must be stone reliable and all things working (heat)

2 - Must make more power than stock.

I went down to his house which is about 45 minutes away and helped him pull the engine. We then loaded the engine is his beast and brought it back to my skunk works: "Exhaustive Solutions".

And thus began the teardown -

But let me back up for a moment. Nando was unsure of just where to go with his motor. Size wise, power wise, money wise, etc, etc.

So I took him for a ride in Black Sabbath - Here is what comprises my motor build:

1.7 liters

Original 1971 90mm pistons and cylinders (almost worn out, I just did not have the money for upgrade when building, which is what many of you, are in the same predicament) These have a fair amount of blowby, and are probably affecting my overall compression ratio by -2 points by guessing..so prolly around 7.1:1 at least.

A SCAT C20 cam -

Weber 40mm IDF's with stock vents, 120 mains and 45 idles with F7 tubes.

Short manifolds

2 liter headpipes with monza manta exhaust

009 with crane optical

Now I am the first to admit, my motor is not "new", nor is it at full power levels had I had the money to do it the way I wanted....

I'll just let Nando tell you all what HE thought-----

Back to the motor: This is one reason why low power----



These are the really small valve 1.8/2.0 heads. W/o cleaning thay look to be pretty good, will know more when cleaned ---



I have some bolt-on power mods I have been working on for quite some time now, and a few will be incorporated into Nando's engine. I am using Black Sabbath as my on-road test bed. Everything I do is backed up by road tests and chassis dyno tests.......Stay tuned for info and pics. (IMG:style_emoticons/default/cool_shades.gif)
