      You can be in my camp if you want - membership is free! We can call it The TR5/250/6 Nirvana Camp. You might lose some friends in the WOS Camp though ( Wheezy Old Strombergs ) .

      Sorry, just can't help myself .

          My buddy, RetiredTrTech's previous 73 was probably pumping out at leasr 150 horses, it was wickedly fast, a hell of a lot faster than my 6, and it had 2, Wheezy Old Strombergs Tom.
          It's still around up here in Sac, still running, so though it was a pumped up engine, it isn't an fragmentation grenade. I do know the CR was 10.5/1.

            I have 3 ZS carbs so the wheeze isn't too bad. With the DCOE's - I've heard that the Italian models are the best, but avoid those from what - Spain? or Argentina? Curious

              Just poking fun.

              Nothing wrong with Strombergs, really, and for the emissions engines their solutions were priced right and worked, for a while at least. I can't think of any really exciting cars that had them though, except the Lotus Elan which rated its engines the same whether they had Weber or ZS carbs.

              The wrinkle with (3) on an inline 6 is that the inlet pairs don't synchronize well with the draft pulsations. Jaguar supposedly fitted a different needle to the center carb when using (3) to compensate. So I contend that a nice running engine with 3 single barrel carbs will run better with 3 duals which give the single runner advantage. This alleviates the need to go with wilder cams and higher compression for the same output. Weber conversions on Jags are commonplace for that reason and even BMW CS, Bavaria and others are being converted, even from fuel injection.

              As for Spanish Webers, I haven't come across anything damning about them, and plenty are fitted to TRs with very happy owners. I would pass on the FAJS copies and even Dellortos for that matter as genuine DCOEs are still in production. Italians are [ almost ] always used and I have (3) such sets plus (2) NOS. The last set is the latest Italian made 151s which, like the Spanish, have the most bells and whistles ( you can synch the idles to a gnat's eyebrow ). But I'm running the oldest set on my driver, 130K miles and counting and an NOS set on my show car.

              As mentioned many times, these TR engines need long duration cams + C/R increase to make use of anything more than a pair of Strombergs. Finally, for a stock engine my strong preference is for the original Strombergs every time.

                I totally agree with you. The DCOE's have been the gold standard I my mind for ever. They would have cost me a small fortune, though, considering the corresponding purchase for the wife.
                The complaint I remember from a non-Italian version had to do with threads & fitment issues. And he wasn't pleased! It's been a while, though. THX

              I dunno Tom, my 68 E-Type is kind of exciting and she's only got 2, ZS's to quench the thirst of 4.2 liters. Still pretty quick too!
              On the Jag, the dashpots were originally sealed from the factory.

                RJB please keep going! I posted a comment, only to try and be helpful not to challenge or question. There are lots of opinions and camps on this and other forums, more than there are dyno charts! I posted mine in the past, some of the most opinionated have yet to do the same, ignore them, I do and it makes my visits to the forum more enjoyable.
                PS Scream if you get over to this side of Lake Michigan!
                Best wishes

                    I am planning on investing in a new cam some time in the not too distant future if i have a decent summer at work. I live relatively close to you as well (48118). My preference would be your option #3.
                    Take care and thanks for your efforts to improve our hobby!

                      The Kits are done, I've sold five in total. I don't have access to a machine shop at this time due to everything going on but can make more if anyone is interested.

                      The Basic kit triggers off the coil - and uses microsquirt in batchfire, I have a basemap to provide as well.

                        Happy to discuss further when things improve for you. Do you have any details of your kits please. [email protected]
