I knew the compression was going to be low on this 440 but I was hoping for a bit more than that. I'm thinking...  Poor old Imperial needs more cylinder pressure. Might have to address that some day.

Well is there a easy way to get them where they should be? What is it, less then 8 to 1 now as I think they were listed as 8.2 anyways. My Neon is almost 10 to 1 factory

Doing the math with the cylinder head, gasket, and piston depth I come up with 8.0 compression. That's a bit low even for forced induction.

yeah I've ran into SCR's in the 7's (measured). If you ain't going into the short block (boring) I'd get a Hughes cam to build at least a bit more psi & tweak the dist subsystems dead on.

Dang Kevin ...You're just not catchin a break with that IMP..Sounds like it needs a complete O/H..with better pistons..,, then why not just stroke it, as pistons come with most kits, While you're in there a better cam , then some better heads while you're doin it , $$$$ Why not $$$$$$$$$$$$$..you know how it go's...Good Luck..Larry
Yeah, I'm fighting that urge. Knowing there is a full EFI system, a pair of turbos, and more 8 piston calipers collecting dust in the garage is killing me.
I'd be installing the EFI system now if there wasn't 84 ounces of R12 in the A/C system. The upper A/C line is a steel, not rubber, and goes directly across the mouth of the throttle body. No way yo put an air filter on it.
If I change the line it would be the proper time to change the compressor.
It's a big ugly slope to fall down. Best to avoid it completely.

I'll never use a carb under boost again. Once you go EFI it's hard to go back.
I'm not selling the parts. I need to get the Imp back together and running so I can concentrate on other things right now.

What we do with R12 is find a buddy who needs some (always someone with an old car who needs some), hook my gauges to the high side on the one car donating the freon and the low side to the recipient, (I use my 134 gauges and 134 adapters on both cars)pinch off the line to the bottle start both vehicles (if possible) and turn on the AC, you can get pretty much all of it out this way (may need to jump the relay to make the compressor keep pumping after the pressure drops too low in the donor car)and it don't go to waste and Al Gore should be happy. When we put the old R-12 system back together we just put adapters on and evac real good and fill with 134. Even if your car is not running you can still get it down under 50 PSI and if you can figure a way to heat the AC system up a little in your car you can get even more out. Whatever you do do not put propane in an AC system ever! there is a shop in town that does and we keep getting exploded condensers to replace

As for low compression just get a custom cam ground with around 205@.050 and as much lift as possible, then add high ratio rockers to get more flow without increasing the duration. I have seen low compression engines like this one 8.4 compression 5.9 magnum I built get 180PSI with a small cam like that. You could even go with a wider LSA (that cam was 110) to help the turbo and not lose too much cylinder pressure.
