I just don't want to have to 'find' a spot in my garage for the engine to sit. Come winter, my wife is going to want to park her van in the garage (I already sacrificed 'my' parking spot for the firebird). Don't get me wrong, I REALLY want to put a 400 engine in it, I already looked at one that a local guy has, but it needs to be rebuilt too. I figure if I could get 350-400 HP out of the 326, that would be good for me. I don't plan on driving it very often (not a daily driver), so the 326 is probably OK....Man, I want that 400 engine..you guys are making me think. I'm going to look at my garage to see if I can store the 326 somewhere, unless someone has a good upgrade combo that I can use. I read in the faq section, that someone got 570 dynoed HP from their 326 (but they did't list part numbers), https://firstgenfirebird.org/FAQ/engine/general.html - about 11 'pages' down "Engine Rebuild (Revisited)"
that is definitely enough power for me (I don't think my current suspension could handle that much).
