New project which direction turbo slant six or 360 magnum efi with od

Is the slant going to be EFI as well? If not, my vote is towards Magnum 360. A bone stock one is 300@the crank from the factory. With the slant like you described, I bet it'd take the better part of 15# to get you there. Also, if you're wanting to take corners, an o/d manual and a gentle power curve would be better than the slant (generally speaking).

Oh, and there's a better chance the 360 is going to be running/in better mechanical condition than the slant as well. I'd say at best the slant could use a hone/re-ring, head refinished, probably some bearings and gaskets too (unsure of the condition, just an assumption) where the 360 *could* have that done, you could probably get by without most of it. But then again you already have the slant...

If the slant were to be EFI, it'd make the choice a little tougher (in my eyes) of a choice. If you like the sound of a turbo, the boosted slant would probably sound good to you. I'd bet you'd get more complements with a n/a V8 rumble, but that's not much of a matter lol

In the end, its really up to you. The V8 might be easier to tune, the sudden hit of a turbo spool would be fun (a .org member has a dyno graph, 90hp@3000rpm, turbo spooled and 230@3300 lol) either will put a smile on your face!
