    WTB L24 pistons

    Time Left: 5 days and 22 hours

    • WANTED
    • USED

    I'm thinking about assembling an L16 I have until I find all the parts I want for my L20B. The L16 is complete minus 1 piston and 1 rod and 1 rod cap. All of the block prep work was done but nothing was ever assembled. Does anyone have a set of usable L24 flat top pistons maybe still attached to the rods for the stock bore, 83mm? thanks Tim

    Cam identification

    So I measured the cam lobe and its 1.465" and the base circle is 1.055 so that's .410" lift. Is that the lift or is it .410" x 1.5 for the rocker arms and then its .615" lift? I thinks its .615 because my L18 cam is 1.585 - 1.300 = .285 x 1.5 = .427 My l16 cam measures 1.575 - 1.300 = .275 x 1.5 = .412 which seem to line up with the specs in the books.

    Early Weber DCOE 40s

    I bought the rebuild kits and a few other parts from the ebay link. Unfortunately my note to the seller to include 175 needle valve didn't make it to him some how and I ended up with 150. Is that going to be too small? How do I know what size I should run?

    Early Weber DCOE 40s

    I have a pair of DCOE 40s that I am cleaning and rebuilding. I think I have early webers, I have brass floats and the spindle shafts have a small piece of leather with a spring and plug to seal them. I'm looking at ordering these https://www.ebay.com/itm/WEBER-40-45-48-DCOE-CARBURETTOR-SERVICE-KIT-WITH-ADDED-SCREWS/263406094171?hash=item3d543a075b:g:HTkAAMXQaBRRi-yw:rk:5:pf:0 I have a 175 needle valve size, will that work for a mild L20B build? If not I can order a different size when I order the kit. Anything else I should look out for when ordering gasket kits?

    Tach surround idea

    I wanted to install a aftermarket tach in my 510 and didn't want to cut up a dummy light cup to fill in around the tach. I found a funnel at the auto parts store that has the same shape as the dummy light cup. Thought this might help someone out, the funnel I used is made by FLO TOOL part number 10718. After some careful trimming Test fit SEM trim black paint The funnel was about $3 and it took me about a hour or so to cut and fit it.

    My Intro

    New member, I joined a while ago and have been mostly reading, searching and collecting the parts I need to put my 72 510 four door back together. It was mostly in pieces when I bought it last year but very clean and rust free. It did get bumped in the back and I'm working on replacing the tail light panel with a replacement from futofab. My plan is a nice driver that my wife and I can autox and have some fun with. I've wanted a 510 for a while but they are difficult to find in the midwest, I'm in IL suburbs of Chicago. I found my 510 in PA and road tripped out there and back in one weekend with my wife to buy it. Lots of great info on this site and I've been spending more time hear than the other site so I though I would just start asking my questions hear.

    Cam identification

    I have a cam that I don't have any specs on. It is for a 4 cylinder L series, it has no oil holes drilled in the lobes and has a red stripe on it. The cam is marked 420 00 on the back and looks like it has provision for mechanical tach drive. It does have the two large squares like a L20B cam. The other markings on the cam are CWC I-5 0-1 K 304 D1 I will try and post some pictures when I find a place to host them, thanks for any help

    WTB 510 rear bumper

    Time Left: 11 days and 22 hours

    • WANTED
    • USED

    I have a 72 510 I'm putting back together and I need a rear bumper and brackets. I was thinking about buying a new from futofab if Dave does his 15% cyber monday deal again. I just thought I would check and see if someone has one in good driver quality shape for a good price shipped to 60439.
