Ramcharger,
1. The lean burn plate takes the place of the vacuum advance pod and the 2 plates that cause timing flucuations when useing a timeing light. Basically it makes the timing when set with a light as steady as a crank trigger. Most timing marks tend to jump around when useing a light so if the plate is bolted or screwed in this case to the distributor housing it has to stay very steady. Then set the air gap at .008-.010 and your done.

2. Well a small block only has 10 head bolts and when cylinder pressures go up over 200 psi it tends to lift the heads under high rpms, and were already around 170-180 psi. Its due to the overlap in the camshaft only being 60*. OK I know run a larger cam and then more compression well this kind of defeats the purpose as first you build pressure and then you bleed it off. With the cam that I used it allows me to keep the Tq better at low rpms and this way I get to use all the cam profile without having to turn the engine up to 7000-7500 rpms. So its kind of a durability thing, and with the car weighing so much and the engine being so small that it needed all the help that it could get, and thats the reason that I built it this way. Which it isnt doing too bad as it is.

3. The combustion chamber and the port work that I did makes the engine very efficient, high velocity and fast burn chambers. This is another reason that I didnt run more compression. Also too that the more alcohol that you get into the cylinder the higher the pressures will be and I'm already running a 102 jet and it has a hole size of .130 X 4 jets plus bleed holes just above the jets that puts another .125 of fuel to it.

When ever you put more fuel to any engine the sound changes and it becomes rougher, healthier or deeper toned, this engine sounds like a roller 360 engine.
