Hello,
i have a '79 towncar with a 400 in it. I was changing the cam, and planned on doing the heads, and build a OD tranny in it. When figuring one and other out, i concluded to go with the E4OD.
Now, in my search for one, i stumbled onto someone that was selling a freshly rebuilt 460EFI with an E4OD attached, including wires, injectors, etc.etc.
it is a '91 truck engine, and has a new RV cam in it, and KB hyperteutic pistons, as a rteplacement.
He clasims the cr is now 8.8 instead of 8.5, and the engine needs a high grade fuel.
Now, i have some questions, as i am thinking about ditching the 400, and swap the 460 in it.
I run on propane only, and very very occasionally on gas.
I was thinking of actually futher increasing the CR. is this possible/advisible?
Are there more power-adders to this engine?
I want to use it for dayly driving with the highest MPG as possible... (that's why i intended upgrading cr on my 400 and putti' in a OD in it in the first place..)
leving some black stripe marks on the pavement now and then is a highly appreciated bonus, but definately NOT my MAIN goal...

Any help/info/links/articles are VERY welcome.

thanks!!!
