HT4100 sucks. What do I do?
Ok, so anyone with any mechanical aptitude that's owned a mid-80's caddy knows that the HT4100 is a money pit. Mine is no exception, though it hasn't (completely) failed me yet.
And I stress YET.
But rather than rebuild a substandard engine such as the one in my 1985 Eldorado, what other options do I have?
I'm planning on making this a project car, and retiring it as my daly driver, at least until the spring.
One option would be to find a used 4100, strip it down to the block andgo from there (aluminum heads being the key change). But apparently mine is the only one in a 200 mile radius, and S&H would make up the diffence in cost if I were to buy a reman.
What I'd like to do is build an engine from the block up, but starting from a more powerful, more fuel efficient template than the stock for my model year. But I don't know what kind of engine would be compatible with the rest of my drivetrain.
Is that possible? Is there something like a big block V6 that would fit and function properly in my vehicle? Would the mounting bolt patterns effect which engine I can get or are there conversion kits available?What problems am I likely to run into with a project like this? How much could I end up spending and where can I save a few bucks without endangering a successful outcome?
I'm still a novice when it comes to this stuff, so any guidance, suggestion, tips, ridicule or otherwise is greatly appreciated.
Thanks!

RE: HT4100 sucks. What do I do?
What year is the car, seems to me is it is not a downsized car you have the Olds 307, 350 or even 403 or Cadillac 368 or 425 as choices. If downsized you are stuck with 4.5 or 4.9 Cadillac.
