High Compression [b]Propane[/b] 60/V-6!

[ssdurango]

I've been having dreams about trying this and It's driving me crazy, tell me what you think....

Take a 93-95 Camaro 3.4 pushrod getting the compression up to around 13-14:1 and running it on propane. Since propane is rated at around 109 octane it should work. The power and efficiency should be amazing if I do it right.


To get the right compression, what do you think I should do:

A) Find or have made higher compression pistons.

B) Shave and block/heads and use copper gaskets.

C) Use Gen 3 head because of there smaller combustion chamber.

What is it going into? The best would be to use a GenIII engine and install iron head pistons with iron head head gaskets. But still you would want it higher. So maybe just some dead flat pistons.

I don't think you need the higher compression for propane. There have been conversion kits available for V8's for years now, and the only engine mod is the carb. Unless you want to use propane BECAUSE of the higher compression.

Sure you can run propane on any gas engine. But it lick balls for power. You need to get the compression WAY up in order to make power.

Wouldn't a 93-95 3.4 camaro block and pistions with Gen III heads turn into the same beast? I know the camaro pistion only have a 7 CC dish.

Do you know the size of a Gen III head combustion chamber?

EXACTLY Why not!!?

Yeah that's the idea. I thinking about 13 or 14:1 for the first engine. Maybe push it higher if nothing explodes.

Oh, it's going into a 1989 S-10 2.8 5spd

I've allready intalled a comp cam, lifters, springs, headman headers 3" flowmaster exhaust 4.3 thottle body- matching intake, oversized alum. rad, E fan, MSD coil

What about using a DOHC motor for it? You could get away with even higher compression then due to the central plug, but the DOHC might have strengh issues.

Thought maybe you wanted to save some money on gas or be more environmentaly responsible or something silly like that.

HAHAHAHAHAHA!!!!!!!

Its going into an S-10 Aaron. DOHC will just be a pain in the ass.

Yea it would turn into the same beast. But I suggested the 3400 motor because it has a few advantages over the Gen I block. BUT since it is in an S-10 the 3400 will not be a good idea it does not fit without serious effort. So can you use alum heads? Yes but the TBI will have to go and so will the dizzy so now you have to install a whole new ECM and ignition system from a MPFI or SFI FWD car. So if you want to tackle that go ahead.

I suggest to you. Get an iron head motor in any size of your liking and use some dome top pistions and get the compresion near the 15's.

Ah ok, that would make for a big pita.

Would you think less of me if I DID want to save on fuel and be more evironmently friendly?

I've been looking all over for 3.4l high comp pistons - no luck

Any suggestions on who to contant. Or do they need to be custom made?
