650

3) Use 1 & 2 or 3 & 4 instead. It would be balanced, but the power delivery would be kinda rough.

Option 3 shouldn't be that bad.
One cylinder would fire every 360 degrees, so it shouldn't run too rough.
It would be balanced if you removed the other 2 pistons & rods.
If you removed the other 2 Pistons/rods you could take off the rocker arms so the valves would stay closed.
Ok you might not want to completely remove the rocker arms due to oiling reasons, but you could cut off the cam tappet side so it wouldn't run on the cam.

No - they would be firing 180 degrees apart, with 2 complete revolutions to fire both. Using 1 & 4 or 2 & 3 would get them 360 degrees apart, but then you have both rods on the same side of the crank, out of balance. Look at the picture of the crankshaft in the Haynes manual (14.1, page 2B-10).

You are correct. I was thinking that the firing order was 1-3-2-4.
Correct firing order is 1-3-4-2.
So it would be in balance and fire every 360 degrees if you used 1 & 3 or 2 & 4. Right?

[edit]
No, I'm still wrong 1-3 or 2-4. Would fire 1 to 3 would be 180 degrees then 3 to 1 would be 540 degrees.
hmmm...
might sound like a Harley. :lol:
might shake like a Harley too :shock:

OK, got Karl's engine home & on the stand and I'm in disassembly mode :-)

Progress! http://www.ws-design.com/festiva/pistonholes.jpg

The more I thought about it, the more I liked the "leave the pistons in" approach. Simple, cheap, and I know it will be balanced.

Hey wouldn't it have been better to remove the valves instead of adding more air to the engine. Engines run better under negative crankcase pressure. Better ring sealing and all.

Nice progress regardless

The valves are staying, but the rocker arms will be gone, so the valves will stay closed. Plus, I'm going to blank off the intake and exhaust ports where the manifolds mount. So the net result on crankcase pressure ought to be zero.

You could probably take the compression rings off as well and just keep the oil control ring on there.
That should help cut down on drag.

[muscle_Car1]

Correct but you'll still move around alot of air.

Wow! The inside of my old engine!

I forgot to tell you Dave, that the flywheel was used in my swap. I do have the old exhaust manifold though, if you want it. I think the intake manifold was on the engine, right?

Could you tell from the head where it was leaking, by any chance?

It's going back together slowly but surely. As of this afternoon:

Oil pump and timing belt are scheduled for this evening :-)

Yeah, I want the exhaust manifold, and yes, the intake stuff is here.

Is the flywheel the same for an automatic and a manual gearbox? Just curious; I'll be swapping with whichever car I decide to put the 650 in.

Hard to tell where it was leaking (for me anyway). Pictures:

Maybe in the circled corner

Maybe in the circled corner

The block was dry and rusty right under that, and I believe Karl said it was leaking coolant, so that may be it.

[25Horseplay]

Thats were I was thinking it looked like a leak too.
