I've done some searching and reading but wanted to make sure I had my facts straight.
What are my different options for upgrading a 14CUX distributor 3.9 to a 4.6?
Here's what I think I know:
1) 4.6 crank and rods will not fit in a 3.9 block?
2) I can put 4.6 crank and rods in a 4.0 block and reuse my 3.9 front cover.
3) I can use 4.0 pistons for higher compression. Can I use 3.9 pistons for higher compression as well?
This is for a '95 D1 project. I've been waiting on a built 4.6 dizzy motor from a pretty well known Rover guy for about 4 months now. No money has exchanged hands but its been a long time and I'm starting to look at other options now.
I have headers to install. I have a 4.2 ECU, a good 3.9 ECU, another spare 3.9 ECU, and a 4.6 non-cat ECU Chip.
The engine is coming out no matter what so I just assume rebuild/replace it.
No, I don't want an LS engine. Ok well I do, but that's more $$$ and time than I want to spend.
Thoughts on my above assumptions or comments on how to best proceed forward?
