LS3 heads, what's the chamber size? Sorry, I haven't been paying attention.

 

^^^True! There is a lot of info left out that is important... It's all about what you want to get out of it and the set up as a whole. I personally don't like milled anything for FI and heads, not that it can't be done but the more meat on the heads the better lol. I was merely sticking up for L92/LS3 heads...

EDIT:Mine are 75cc... correct me if I'm wrong they come 72cc

 

if not mistaken theyre 70cc but i also seen them advertised as 72cc but mostly 70cc , i know the decks are just shy of 5/8s of an inch.

 

Right now I'm just going with a stock bottom end and good arp rod bolts, head studs, and mls head gaskets. I only plan on running 6-9 lbs. Just want it to be dependable. Not looking for a monster quite yet lol. Hope this helps understand more. Sorry about the quick op.

 

Is your KB 2.2 not limited to cathaderal port heads?

 

I dont think so?

 

It's going to be pretty much either/or. A top mount 'charger won't fit both catty port and square port.

 

kb is a side mount blower.

 

The pictures of KBRacings Kenne Bell sure look like a top mount, and I'm pretty sure the new 2.8LC for the Camaro are top mount. Don't know anything about the older Kenne Bell units(other than rumors of problems with high IATs).

 

I'm pretty sure the 2.2 is a side mount blower. Mine is a 2.8h. It's basically a Corvette kit with a different snout. That's why my TB is on the drivers side. From what i understand they only made about 10 kits like mine.

L92's would work fine for your build, that 2.2 won't make enough boost to be a problem on a 6l and L92's will take more FI then a lot of people give them credit for. I've got a buddy with a TSP 408 and S488 turbo running 11-15psi in a 63 Nova and it's holding up fine with nothing but stock L92's and good springs.
