Slant 6 Turbo 68Dart Project

Power gains from overbore will be minimal. The only advantage I can see that comes from overboring more than necessary would be more room for big valve without shrouding. IF you were to go to big valves (which is an option I wouldn't throw out the window just because your std valves are new) then the .030 would be all that you need to prevent shrouding on the engnbldr valves (1.7/1.44) Even then, I was told those valves would still work wonderful with a stock bore size.

It's been drilled that forged cranks and cast don't interchange. Dutra has done it in one of his exotic motors, so it's not impossible. But it may not be worth the work. I don't know what all is different though... I do know the connecting rods are different. Cast is narrower at the big end, forged is wider. I'm thinking there must be something else as well... Your call either way on that one.

Hmmm. It does seem odd me not saying something negative... Oh, wait. LEARN TURBO MAPS! While your at it, get a decent turbo! :evil3:

Seriously though, that's the base of a good build, that's why it's called a turbo slant :razz::thumbrig: Maps look all confusing and stuff, but once you get the hang off it it ain't too bad. I may try to find you some useful links that helped me learn stuff. Also, the turbo is what ultimately decides the end power you make. Case in point: Tom's "stock" slant with a turbo on it. 23 pounds of boost and he barely made 300 horse. The reason? (IMO) He used an old Regal turbo. Ancient tech and poor efficiency. I'm not saying I'd get top-of-the-line stuff (I certainly wouldn't dish out for that!) but get one that's properly sized and has decent effeciency. Turbo maps will show you what are good and what are poor, both for your app and in general.
