1973 340 issues.

Hey all.

Well I finally got the 340 and 4 Speed transplant done in my Aussie Charger but the 340 is a tired worn unit that really needs a rebuild but the cost of the transplant and the other mechanical work that the Charger needs this winter does not allow for that.

So the '73 340 has been dropped in and semi-tuned by the local shop and runs fairly well but not as much a difference over the 318 that was pulled as I had hoped. Will still fry the rear tyre in first and a chirp in second though. Now has a stock Dizzy, New Cap, Leads and Plugs and a Weiand Action Plus Intake and a used 670 Street Avenger. Im also getting a lot of blue smoke on hard acceleration (seems to be only on hard acceleration) so I did a Compression test just now and the figures are not great at all. I ran the engine till hot then left ti to cool slightly for an hour before doing the Compression Test with a cheap kit I bought. The Lifters are also noisy.

Cylinder #1 = 120psi
Cylinder #2 = 30psi
Cylinder #3 = 115psi
Cylinder #4 = 110psi
Cylinder #5 = 110 psi
Cylinder #6 = 80psi
Cylinder #7 = 110psi
Cylinder #8 = 85psi

As there is no way I can afford to pull the 340 and rebuild it this year is there anything I can do to potentially get the Compression back? What are the issues with running the 340 as it is now? Any thoughts or comments greatly appreciated. :)
