It's all nuts and bolts man. I think it's funny how some people get bent out of shape about using a different maunfacturer's engines, yet use aftermarket parts on thier cars made by a different manufacturer. Welcome to hot rodding, "Built Ford tough with Chevy stuff" has been around since the dawn of time. If you already have a stash of SBC parts to pick from, go for it. I've heard AJE's K fits a small block very nicely and gives just enough distributor to firewall clearance. I have a couple SBC's around here and I can't say one of them won't end up in my car in the future. BTW, you can go with a motor plate and just cut your stock motor mount perches off the K. This would allow to move the engine around wherever you want to put it and costs less than $100 for a front plate and about the same for mid plate.
