Redneck Re-curve

Hey 67/6barracuda!! I checked out your post earlier but didn't write anything. But, let me tell you, you posted some great pics and I appreciate the details you included in your post!!

And don't apologize for you home made set up (it's called ingenuity). The great majority of FABO members don't have the money to buy all the fancy tools required to improve their engine performance especially when you're only going to use the "special" tool once or twice in your life!!
The only question I have is , "what's the purpose of the "protractor thing" that you put on top of the distributor (first pic)?? It looks cool but what's it for???


thanks,

Treblig,
The protractor was used to determine the true mechanical advance in the distributor. What I did was bent over a cotter pin and tape it to the rotor, then positioned it at 0* with the shaft of the distributor locked down with the vise grip. I then can turn the rotor and figure out the mechanical advance. In this case it showed 12* on the protractor. You then have to multi by 2 to get crankshaft* so therefore my distributor had 24* mechanical/centrifugal advance. I wanted to be around 18* mechanical so I loosened both adjustment screws in order to take out some timing. I set it at 8* on the protractor multi again by 2 and I get 16* of timing in the distributor. Now I can run more initial timing which ill set at 18* to give me 34* of total timing. I hope I answered your question. Thanks again Treblig...oh by the way your exhaust manifolds are still working great on my car.
