Perhaps I should be more specific:
I am about to swap into my third gen firebird a 5.3 engine. The wiring for FI is daunting, but I love the LsX based engines. All aluminum are too expensive for me so I bought a 5.3 from a junkyard for 500 bucks including tranny (not bad, huh?). So, I hear carbs really let any LSx based engine breathe and are simpler to install. I was curious if anybody has power numbers for said swap including the bore and ported heads, or stock.
