    LSx bare iron block vs. bare aluminum block... 102.8 lbs difference.

    Iron... 197.0lbs

    These were weighed on the same scale on the same day, and both were stripped down to the bare block. The iron block is a 2005 LQ4 and the alum. block is a 2000 LS1. Weights were taken by BrianV8Z, BRAAP, and myself.

    The 621 reproduction bell from Keisler Engineering showed up...

    The plan is to mate it to a massaged TKO600 from Liberty Gear.

     

     

    There's been plenty of debate on the weight of an iron block vs. aluminum. I wanted to 'know' the difference and whether the there was enough difference to put an aluminum block on my wish list. The truth was a little more sobering than I had expected... 102.8 lbs difference.

    That is not abnormal. With one tire in the air, the only thing loading the clutches is whatever pre-load there happens to be and that's not normally enough. Once both tires have some grip, the side gears have something to work against and can load the clutches up MUCH more.

    It's in the same class putting a Vellarossa body kit on an S30, trying to make it look higher performance than it is or at least look like something that it is not.

     

    No, it’s not. Aesthetic modifications are very welcome here. When they are taken so far that they render the car useless THEN it is too far. That’s where the “thoughtful” part comes in.

     

    I guess they should all be kicked off the site for not actually "using" their cars then, eh?

     

    Enough. Really. Not one member in the history of this forum has ever been kicked off for any modification, aesthetic or otherwise.

    Since this topic is coming up with increasing frequency... If a member is posting his slammed car with 195's stretched over 10" wheels because he doesn't know the difference, I have no issue with it. He'll learn by his own experiences and perhaps with some help from our members that some of his choices may be counterproductive to a sports car/race car. When a member posts the same with an "I don't give a F*** what the consequences are, I'm cool." then he is on the wrong forum. There are other forums that welcome that style and that's their function. It is not the function of HybridZ.

     

    Every generation of Z was designed, built, and sold to be a sporting car. This forum is about getting the most out the Z, not the least.

    Does the car still have the fuel tank stup you made for it?.

     

    I kept the sump and pump, but discarded the tank before I sold the Z.

     

     

    Are you going to leave the paint and body as it is in the pic?.

     

    I would like to paint it someday, but it's at the bottom of the todo list.

    About 9 months ago, I sold my late 260 to Mongo510. This was the same car I had put the BMW S52 drivetrain into... M Powered Z

     

    I was distracted from Z's for a while and even built a Locost frame that I sold to a local friend who is now gracing it with an F20C. Can't wait to drive it!... Locost

     

    Skipping a lot of details, Mongo and I were talking and he told me I could have my 260 back. I chewed on that one for a few weeks and pulled the trigger. She's back home...

    I've always liked this car. It's never been hit and is as rust free as any un-restored Z I've ever seen. It's ugly but it's solid. (Thanks Mongo!)

     

    I put a bug in BRAAP's ear that I was looking for a 6.0 liter. Before the day was out, he had found me an LQ9 w/130K on the clock. It spent it's life in a 2002 Cadillac Escalade, so there's a fair chance this motor has lived an easy life. I made a deposit on it that day and brought it home that weekend...

    This motor is the "HO" variant of the LQ4. A little more CR (10:1) and a slightly more aggressive tune put it at 345hp and 380ft/lbs.

     

    Stripped it and set an LS1 intake on it...

    What can I eliminate from my engine bay?

    You have to admit though Ron, a lot of the reason that '60 chevy has so many vapor emissions has a LOT more to do with aspects other than just vapor leakage from the tank. The actual gas cap doesn't seal for anything, and the carb's float bowls aren't anything close to sealed either.

     

    Agreed on the carb. The gas cap is kinda moot though. The tank must be vented and it was often done via the gas cap. With the advent of canisters, caps were all sealed and venting was done via the canister. Those two go together like popcorn and butter.

     

    Steering this back to the original post… This a fuel injected car with a sealed cap. The tank must be vented (in & out) and a canister is an efficient solution. It weighs next to nothing, requires almost no maintenance, doesn’t consume any power, and does a pretty good job containing fumes. Yes, they are ugly. So hide it. The yellow car In post #2 has one… it’s under the fender. To me, it’s a no brainer.

    EVAP cans, though reducing HC in the atmosphere are a very good example of governments spending 90% of the budget on squeezing the last 10% improvement left over.

     

    Sorry Gollum, I see it quite differently. A 1960 Chevy pollutes more parked and off than a 2000 Chevy does going down the highway. The evap. canister is a substantial piece of that pie. I don’t see anything incremental about it. I understand this thread is not about emissions compliance in the legal sense, but I *DO* care about the fumes filling up my shop. In no way could I declare it inconsequential.
