Hi guys, I've been working on cars for almost 10 years now, and have owned/worked on Mustangs, GalantVR4's, 300ZXTT's, but I'm new to the 240Z/ L series engine/carburation, and i have a few questions. I've been doing a lot of searching and haven't found the answers i'm looking for so i thought i'd post my questions. Can the L24 be a powerful/reliable engine? Every thread i come upon says to use an L28 block, yada, yada. But they don't ever say why. What is the weakness of the L24? I'm picking up a 72 240Z tomorrow and it has the original L24 in it with double SU's. It runs like crap now and wont barely start (needs a tune up, ect). My original intent was to do a Hybrid-V8, RB motor, ect. But since the car is original, and swaps wind up costing a lot of money, i'd like to tune the L24 to make some decent reliable power. Is this posible or am i wasting my time? If i rebuild the SU's and do the Pertrox electronic ignition, can i make some decent reliable power? (200-300 HP range) Are triple webers a better setup? I have a guy that wants to sell me a triple weber setup (manifold/45mmcarbs) for $300. Is that a good deal? Sorry for so many questions in one thread. Your help is greatly appreciated. I look forward to posting here and getting to know some of you. Thanks, Jay
