Hypothetically, if I'm wanting to build another 0-320 with the intent to get as much h.p. from the engine as posible, and still keep it as legal as posible, what steps would I take? I realize keeping it "as legal as posible if like being kinda pregant", thatswhy this is strictly a hypothetical question.
The way I understand compresion ratio's for an 0-320 the 7:1 should produce about 150 ponies, the 8 1/2:1 produce's around 160 ponies, 9 1/2 : 1 should put it in the 178 h.p. range, and the 10:1 around the 184 h.p range.
Ly-con seems to be producing good results w/ their head work.
There seem to be two popular carbs, from memory the last two digits in one of themis a -13, and the other is a -8. A factory Presision Carb guy told me once that one flows more fuel than the other, meaning making more ponies. I need some help in this area. Any carburator suggestions are more than welcome. Any work to be done to the intake/oil pan?
How about making all of the intake tubes the same lenght, comments on h.p gains?
Nearly all 0-320 that are in common use seem to use the same ignition system, either bendix or slick mags. Is there any other options to put more fire into the engine? I'm already sold on the Iridium spark plugs, anything else to gain ponies from the ignition system?
Nearly all race cars use some type of direct drive system for the accesories. I'm just sure the standard alernator belt is pulling some h.p. from the engine, as small as it may be. I have ask this question before, any calulations to figure what you might "gain/save" by running the small atlernator (direct gear drive) from the assy. case?
Is there anything else I'm NOT thinking about? A well balanced engine w/ every aspect built w/ performance in mind. I'm fairly certain I'm up to date w/ most of the weight saving issues, now I need more power!
