Well here is my dillema... i have a bee in my bonnet to have a 700hp ish in daily driven street trim, 1000hp with race gas aluminum block setup. LSx's engines AFAIK are not reliably able to make that kind of power. I could go with an IRON block LSx, however, i really want to take advantage of the weight savings of an aluminum block.
If someone could tell me that i could have an 700-800hp twin turbo LSx Aluminum based setup that could be daily driven, i would consider it. Since i have not found anyone that can tell me that is the case, then i am now thinking about going with a world or dart aluminum small block setup possible with AFR 18 degree heads and a hogan's manifold.
Does 18 degree heads make it any easier to build turbo headers? I would think that since the angle is closer to the deck of the block, there would be slightly more clearance between the inner fenderwell and the exaust ports???
Maybe for my use, 18 degree heads are way overkill... can that kind of power be achieved with a nicely massaged set of 23 degree SBC heads?
