Road race motor

[Frenchy]

Ok well since the dragstrip is 2.5 hours away and there's a lot of nice twisty roads around here I have been getting more and more into steering. And I've always been a fan of trying things nobody else does, I was throwing the idea of building a real high revving up top screamer. Was going to do it with a SBC just for pure cost factor, but I have a worn out 5.3 and a 4.8 shortblock that I've collected. So I was thinking put the 4.8 crank in the 5.3 block bored to 3.90 (LS1). This would give me a 313ci motor, I figured with a longer than stock rod (havn't figured out how long yet) it should be a good top end setup, and I'm talking 8500 rpm plus with a good balance job. I'd shoot for about 11:1 as far as compression goes and with appropriate heads and cam, LS6 manifold because well a FAST is outta my price range for now. And for the record this would not be going in a full size truck, thinking Mazda2200 or a Toyota, something like that.

Thoughts? Opinions?

Edit. This little beast has a bore/stroke ratio of around 1.3:1, guess which engines are also like that? Z/28 302, Ford 289 and Mopar 340. They're all proven high end beasts.
