I've been thinking about a triple carb set up and was wondering what things should be considered before installing such a set up. Currently my 72 has the stock L24 with a few mods i put on such as msa 6 into 2 headers, ZTherepy SU carbs with air horns and filters, a 2.5 exhaust, and a crane electronic igniton. I also took off all the smog stuff like the air pump and air galley. I invested the money for the ZTherepy carbs so this is not something that's going to happen right away but i know there are members with experience with triple carbs and i'd appreciate their input. Should i dump the L24 before i really get serious with triple carbs, or can good hp be found in this …

im looking for a new muffler for my new 71 Z. the muffler on my wrecked 72 was awesome....but i have no idea what it was (i didnt install it, the previous owner did). i think he said something about dynomax...it was a loud one and i loved it. the previous owner had put on a new header and exhaust, but the exhaust hung down quite a bit (i dont think it followed the stock tunnel). but i dont care about that, all i want is that muffler back but the insurance company wont let me take it. so does anyone here have a dynomax or something thats pretty loud?

Does anyone knows what will be the setup for a short stroke z engine , Im been reading that the setup will be a long 280 block with a 240z crank and 240z rods , now my question is what is the Pro and con of a engine like this . I know that the power band will be at high RPM rev , but because Im going to build my engine with a 560 lift and a 300 duration cam , I would say that an engine like this will rev and operate better , but because I have never done this I want to know if someone have done it or if someone have any info on this setup , thanks for any info . Take care ...

ok, so i bought my first 240Z a few weeks ago, and it was running really sluggishly, so was looking around, and i saw that the hose to the advance was missing, so i fixed that and it gave it more power, but still not close to what it should have, so i checked the spark plugs, and number 4 was wet. I took the compression, and all the others were around 145-130, #4 was 0. so i took the valve cover off, and there was a rocker missing! so i got a new one, and as i was putting it on, i noticed that the valve spring was sitting much lower than any of the others, just wouldn't come up. so i just took the head off, which was fun for my first time taking one off, and thank god …

Hey. I just bought a '74 260z 2+2... It's been standing for a long time, bout 8-10 years i think :eek: So i think starting it is gonna be hard. I was thinking bout maybe putting a RB30 (turbo) from the Holden VL Commedore in it. I've seen it done in a 240z (picture). Just wondering how hard it's gonna be? Would it bolt right in? I'll probly get a front-cut or a whole car, so i'll have all the computers and stuff... Also wondering if anyone knows if Holden VL Calais turbo brakes would fit on the 260? And last of all, i'm just for the hell of it taking the old L26 apart, and i'm just wondering if anyone knows how to go around getting the head of, it cant be done withou…

Hi Everyone, Question, rod n rod caps, are the notches on the same side or opposite? Got my engine balanced and the rods came back with numbers but some have notches on same side and others have them on the opposite side. Checked with book and it doesn't mention any place about orientation. Thanks a Mill,

Here is my concern. My Z will need a valve seals job. I got 2 options in my head. 1. Is it better to replace the valve seals and check the timing chain at the same time. I may have the valves cleaned at the same time, I mean remove the carbon deposit on them right? 2. I may have a real deal on a used head from a 73 240 I think. Is it better to put a head with less mileage on my engine or what else? And BTW, what is the difference between a E87 and an E88 head? Thanks for your CONSEILS!!!!! What would you do?:sleep:

I have decided to go with a V8 conversion on my 70 Z. I am probably going to buy a crate chevy 350. I will probably not do the conversion myself because I want it done right. From what I understand there is a conversion kit that I can purchase from Motorsport. Does anyone have any feedback on that kit. I am also looking for someone that knows what they are doing, to do the conversion. I live in the San Francisco Bay area. Mark

Ok, another technical ?. The Z I'm buying will need a job on the valve seals. Is it long and expensive (in US$, I will make the conversion in CND$)! The owner told me the car is not smoking when running, but the engine is burning some oil... And, for the timing chain, is it recommended to change all the parts to do a clean job using that kit?? http://www.courtesyparts.com/S30-TBKIT.html Anyone did that before? Thanks for the inputs!
