I've had 8v and now run a 16v. 8v's are 'easier' to drive, but you can't beat the scream and revs on a 16v!!! My valver is off the road from Monday for some much needed attention! When it comes back, it should have no injection and twin 40's for a bit of fun!!!! 
Twin 40's ? Tasty

.
What setup you going to run? Considered something similar when I do my ABF, but somewhat defeats the purpose of an EFi lump....
Had a weber on my old Driver and it sounded great, so twin 40's should sound twice as good.
On topic, the KR engine is like v-tech, happy to tootle along sub 3500k then 4k to 7500k screams it's head off, but you need to usually be a gear lower than you would need to be in an 8v just to get it in the power band. Basically you need to stir the stick to get the best from it but that just makes it more of a drivers car I think.
