What does your exhaust consist of? If you have a crossover tube just eliminating that may get you a little more rumpity rump. I've seen a few examples of that over the years.

i don't think you'll ever find a stock 340 with more than about 9.5:1 compression. For a streeter
you might not want to go above about 220 degrees of duration.

This^^^^^^^^^^^^^.

Pretty rare to find one at 10.5:1 from the factory.

If I recall correctly my stock '70 340 came out to about 9.75:1 when I rebuilt it last year. This is after new valves and head milling.

You might want to rethink that nasty idle. It may be telling guys how you're car performs.

You think the raw 110 dripping out the tail pipes might be a bad thing?
