Bloodthirsty as always, aren't you Bill.

I've had several propane vehicles. None has ever done anything more
dangerous than a loud backfire. Propane is inherently a safer motor
fuel than gasoline.

Why you regurgitate spiteful and nonsensical things like you do is
beyond me.

Re: Bill proven wrong some more (took some time).

Then why aren't you driving one right NOW! Oh please God let him
have one!

Re: Bill proven wrong some more (took some time).

Sounds like a plan - will investigate that then.
Cheers guys.

Re: Bill proven wrong some more (took some time).

Dave, when dealing with a low compression engine, there are a few things to
keep in mind about engine modifications. The biggest one is the camshaft. Be
careful of the cam duration and also the lobe separation angle. These 2
factors are critical to cylinder pressure. The best way to cam these engines
is with a shorter duration, high lift cam. Also look for a camshaft with
110-112 degrees of lobe separation. Lobe separation is often overlooked in
cam selection, but it is critical. The higher separation angle will do a few
things. Fist, it reduces valve overlap, which is the time that both valves
are open during the exhaust stroke. The reduced overlap will improve low RPM
torque and idle quality, but at the expense of top end power. Bringing the
lobe separation angle down, conversely increases valve overlap which will
decrease idle quality somewhat, and also improve top end power.

A few other things to keep in mind. LPG likes high compression, so if you do
rebuild the engine, take that in to account. Your idea of aftermarket intake
and exhaust are also highly recommended, but again be conservative on
manifold runner sizes and header tube diameters. The smaller passages will
keep the air velocity higher at low engine speeds, which will improve
torque, drivability and efficiency. The Edelbrock Performer is a good
manifold choice for these types of vehicles. Keep the exhaust header tube
diameter to 1.625" and find the headers with the longest primary tubes you
can. This will improve low to midrange power.

One thing that might improve your situation very inexpensively is ignition
timing. Because of your low compression ratio, you should be able to
increase the ignition timing with the fuel you are using. Unfortunately this
is probably not just a "turn the distributor to advance the timing" fix, but
would probably require lighter springs and different weights in the
distributor. I believe Mr. Gasket still offers an AMC advance curve kit
which would fill the need pretty good.

I guess the timing would be the first thing I would mess with, because it is
the cheapest mod you can make, and next would be the headers and exhaust,
based on return of investment to power ratio. Again, just be careful not to
get too big on the tube diameters. Just keep in mind when selecting parts,
that your goal on a low compression engine is to keep the air velocities up
in both of the intake and exhaust passages. Do that and you will be fine.
