If it had a blower, id be in it like white on rice. Perfect color, and too much rear wing. I'd have to fill the holes.
You do not have to grind the block, you grind the timing cover. (Edit: on 15's, there may be a small pet to grind on block in the valley, still a no big deal deal). And if that bothers you, either do more research or don't mod anything at all. I've done it 3 times now and put one back to stock. It's seriously no big deal.
