You should be able to floor it in high gear, at low rpm (by low I mean loooow, i.e. 1200rpm) and have the car lug but not bog. If your main is too lean, the engine will die. There is plenty of air-flow to get enough fuel, your carbs are just not set up right. I 'll also second Tony's statement about the pump shot, you're either too lean or too rich. I suggest installing a wideband O2 sensor and gauge so you can understand what's truly going on. To EVERYONE using Weber DCOE's, join the Sidedraft Central Yahoo Group and at the very least read Keith Franck's "White Paper" on tuning Weber sidedrafts. Keith is a retired LBNL engineer who has been reverse-engineering the Weber DCOE for the last decade or so. Read the files, links and threads to catch yourself up. He's developed new idle-jets and e-tubes that perform far better than Weber's own. There is no good reason for a triple-Weber'd Z to not have EFI-like tractability with the performance to boot.

Yes! Heat is critical, no matter which method you use!

Nice, must be a fun car to drive with all that torque!

Dagger in the heart! Is there a :passout: emoticon?

Nice, that thing sounds mean!

This has been discussed in excruciating detail. Look at the exhaust sticky, and I'm sure it's been mentioned elsewhere on the forum. In a nutshell, shorter primaries will shift your powerband to higher rpm because of resonance tuning.

You sure as hell will have fumes coming in the cabin if you route your exhaust through the fresh air vents!

As Tony said, you're keeping power away from yourself. Switch to a 10W-30 with ZDDP and everything will be happy.

Good luck. I suppose it's somewhat possible to use stock EFI, but no way in hell I'd want to even attempt that. Going with triples or standalone EFI is a much better solution.

My god. That is heartbreaking!

If you're interested in buying, why not go and check it out in person?

Zed is right though. If your only goal is to replace points, then put in either a Pertronix unit or a ZX dizzy. EDIT: I HATE typos!

I'm setting up EDIS on my triple Weber'd Z using Megajolt. You need the EDIS stuff, a trigger wheel, sensor mount, controller and associated wiring. I'll break it down in my build thread once I'm done.

I'd be more concerned about ground clearance than anything else.

When I was about 19, I told my dad that I wanted a project car. I really enjoyed working with my hands and cars were always a passion of mine. It runs through my blood, many members of both sides of the family had been machinists and engineers. I had mentioned my notion to my dad casually and really didn't think much of it, not even about what kind of car I'd want. That summer, my dad tells me that he found two Porsche 944's for a good price, $900. I instantly got excited! However, the cars were sold before we had a chance to go out and look for them. For the rest of the summer, I trawled Craigslist for a cheap 944 since my summer job didn't allow for spending much. I loved the look of the car and through my research it seemed to be a fun, light and nimble car. By the end of the summer, I had checked out just one 944 which just didn't work out. I went back to school, fantasizing about 944's of course, until the next summer came around. I was working and saving up so that I would be ready to jump on a 944 as soon as it popped up. Finally, I had found it, a black '87 944 advertised for $900. I offered the guy $700 and he said he'd take it. I told my dad and he was all for it, so we set out for the hour-long trek that weekend to check it out. I called the owner and told him that we are on our way. The excitement was building mightily! We reach the house, and I spot the car with joy in my eyes as we pull into the driveway. We roll our windows down and say hello as the owner approaches. The reply was not what I expected, "hey, I just sold the car. Sorry." I see some guy walking to his truck with the pink slip in hand. As quickly as we pulled in, we pull out of the driveway and drive an hour back home. As upset as I was, my dad helped me understand that it just wasn't meant to be, and as I've come to find out, he was right! After my disappointment, I vowed to expand my search. Having only really looked at one 944 within the last year, I was a bit frustrated. This was partially due to not having a big budget and also my dad not having much time to come out and look at a car with me. So the search expanded, I'd look for 944s, 928s, even browsed the 924 listings from time-to-time, which did nothing but convince me not to get a 924. I thought about what I liked in the Porsches and expanded the search to "something with rear-wheel drive, a manual transmission and preferably with a hatchback". This included mostly MkIII Supras and Z-cars. I noticed a trend in my searches, the Z-cars seemed to be the best car for the money within my criteria. Not knowing much about Z-cars, I didn't discriminate between 240Zs, 280Zs or ZXs, however the possibility of owning a 280Z or ZX was quickly decried by my father who declared them too heavy and a burden to have to smog. Thus my Z-car selection was whittled down to essentially just the 240Z, as I hadn't really known about the 260Z at the time. I'd graze on Craigslist, multiple times a day. It was becoming a hobby, bordering on obsession! Finally, there she was, a blue '71 240Z advertised for $800. I decided to drive down and check it out myself, as to not get held up by my dad. I made the 30 minute trip and met with the owner. He was also a young guy and he had a clean MkIII Supra Turbo in the garage! I checked the car out, it didn't run although it apparently did 6 months ago until "the rear carb started acting up", had a cracked headlight bucket so that the air dam sagged down to the ground, had rust holes in the rocker, dog legs and fender and was covered in dirt and cobwebs. Needless to say, I had second thoughts and decided to go home and sleep on it. My head was clearer the next day, and it just wasn't worth the $800. I decided to throw a number at the owner: $200, although it seemed outrageous even to me to offer that much money for a complete car. I called the owner that evening and explained my concerns to him. He was willing to go to $400 so I retorted with, "okay, sorry about taking your time, but I'm going to have to turn you down". He seemed surprised that I didn't take the offer, but said thanks, and I was back one my way to wandering around on Craislist. I explained my decision to my girlfriend, and she was surprisingly adamant in telling me that "it's just $400, if it doesn't work out it's not a big loss". That girlfriend is now my fiancee . I excitedly called the owner back up and told him, "I'll take it for $400 and will be there shortly!" I drove down with my girlfriend, AAA card in hand, and filled out the paperwork for my first car purchase. The tow truck driver was enthusiastic about towing the Z. He hoisted it up onto his truck and his first question was, "you gonna put a 350 in it?" I quickly hopped in my car and followed him, gazing proudly at my newfound joy. I got home just before the truck and prepared the driveway, making my mom, brother and sister curious. As the Z was being unloaded from the truck, my dad drives up the hill, exclaiming in a tone with a combination of surprise, doubt and excitement, "what the hell are you doing?" Here it is the next morning, after the first wash: That Z is gone now, but many of her parts still lay in my garage waiting to be used!

All US street-legal automotive engines since about 1965 have PCV, whether it's a Honda or a Nissan doesn't matter. That crank-case vent has nothing to do with the smog pump, and should be connected to your intake manifold via PCV valve, as Ross alluded to. Download the FSM at xenons30.com and you should have most of the info you need. The rest is in the archives, so use search tools (I prefer Google) to your advantage.

I'd love to have a quad-Weber V8 underhood! My triples haven't given me much trouble, I haven't really touched them for over a year.

I believe all pipe threads on a stock Z-car are BSPT, but someone correct me if I'm wrong.

I love it!

Not a fan either, I prefer the clean look of the black intake and valve covers. But if you like it, then go for it! You can always build a second Z with quad-Webers...

Perform the tests clearly outlined in the FSM.

Connect the control arm to the strut first, and then connect the control arm to the cross-member. The spring is unloaded, which is why the control arm is at a higher angle. Also, attach the TC rod with the wheels on the ground, it's much easier that way. There is no need to use a spring compressor nor a jack under a control arm here.

Bingo!

Dan is right, but there is a lot of info here on how to get your swap CARB certified. If you want to keep the '77 and do a swap, do some searching and you should find some very thorough information. Good luck!

Sounds like fun! Hope you don't have any neighbors within earshot...
