Newbie (sort of) needs some ideas...
Well, my buddy got himself a Gremlin for Christmas with a straight 6. So now he's behind me not doing the V8 swap...lol. I think I'm looking to get something I can do in steps. The eventual "perfect situation" might be a single turbo. I cannot see the logic of building for a supercharger that robs so much power when it's only a little further to go turbo. I know V8 guys have used Ford's EFI to run mopar V8s.. I wonder how hard it would be to get the 300/6 EFI to work on a mildly boosted slant. I could prob get a whole truck for $200 for that.
I think you might run into some really difficult-to-deal-with problems by using a normally-aspirated fuel injection system on a turbocharged engine, but that's just my opinion.
The trend seems to be to use a 4-bbl manifold with a blow-through modified Holley carb on top, because there are lots of people doing the blow-through mods and the Holleys are available in a variety of sizes that fit lots of different sized engines.
There are a couple of things that nobody's pointed out about a /6 that has been turbocharged relative to street driveability:
1.Turbocharged slant 6's seem to like a cam with minimal duration and overlap. This means that although you may have a 10-second car, the idle will be smooth because of the overlap situation.
2.The really fast turbocharged /6s seem to perform better with rear axle ratios UNDER 3:1... that would be around 2.91:1, or even 2.76:1. That would mean you not only a smooth idle, but great highway gears instead of a 10-second, 340-powered car's raggedy idle at 1,200 rpm, and 4.86:1 rear end gearing,
Couple those two items with the fact that turbo cars are QUIET, and in order to keep them efficient, ten-second 340s are
LOUD, so, if you want a sleeoer, or just a nice, quiet F-A-S-T daily driver, a turbo /6 is really worthy of consideration!!!
Oh yeah; a turbo /6 is about a hundred pounds lighter than a "built" 340...
