Building custom; Evo or TC?
If you were building a custom would you go Evo or Twin Cam motor?
I would love to use a SE TC110 in a ST fram with about 34 degrees of rake and 200 or 250 rear tire

Thanks Mimo, why Evo?

2.- Evo carbed is a muchmore reliable engine (in my opinion).
3.- Nothing, and this is NOTHING beats the sound of a shaking carburated Harley Davidson.
4.- You write like a gentleman, a man with class. Anyone can tie a tie, but a bow tie???... In Evo engines you can stick yourarm through the intake and see your hand coming out the exhaust, get the idea???
Evo= Bow tie, cuff links, etc...
TC= hook tie and dockers...
Best regards.

RE: Building custom; Evo or TC?
I'm not sure but I think the evo's all around will be cheaper and stock evo, tc88, and tc96 are all really close on power providing the same mods done. If I ever build my own bike I'll take the time and money and do it exactly the way I want. Which would mean at least getting an R&R 127" evo.
Although in most of your posts, Keith, I kind of got the feeling you were more than satisfied with stock 96" power, so maybe the HD engine will be right for you, but at the same time S&S engines still have extremely good quality and you could get an evo that's 80", or you could get the shovelhead engine they have. Modern reliability with the smaller engine sizes with retro styling (and lots of people say shovelheads sound the best, but I haven't really noticed too much of a difference).

RE: Building custom; Evo or TC?
S&S would be my personal choice because they don't cut corners and have some reliable and powerful engines. Over the years Harley has made changes to each generation of engine. Some of those changes are improvements, but others are just to cut costs and the new setup is worse. S&S tends to only make changes that are improvements and leaves out the ones that cut costs. Notice that I said "tends"; there may be exceptions to what I just said.

A Twin Cam (NON-counterbalanced, or "A")with gear driven cams and a nice jetted Mikuni 48.
Internalson a Twinkie are much more sturdy than the Evolution. Better oiling system, better cooling due to larger fins. Evo's are nice no doubt...but the TC88 only has one real weak link...the chain driven cams. Fix that with gears, and you're good. When the cams are changed over, upgrade the bearings with Torrington style bearings, and S&S reed valve, and a Fueling oil pump, and the motor will go forever!
The main thing that makes the TC88 better is that the pushrod angle is less, more upright, so less side torsional load/wear on the valvetrain parts. The rod and Main journals are much beefier, and again, the oiling system is superior, in that the pistons are cooled with pressurized oil under the skirts.
I know many will flame me....but a gear driven Twinkie is the best.

RE: Building custom; Evo or TC?
Well,... I have owned a few other nonH-D carbed bikes and I honestly can say that I will not own anything but an injected bike now. I admit you can make a cooler looking carb bike because you wont have all of the FI stuff to try and hide or at least try and make somewhat eye pleasing. And the sound ofthat "potato",... "potato",...is just music to my ears.If you want, "eye candy" then a big and powerful Evo would definately be cool and eye pleasing, but if you want a "rider" that you can take for several hundred mile trips and not just a bar hopper than a fuel injexted TC would definately be the one to have. I would love to have one of the new SE Dynas with that 110" but my wife has mentioned about 25,000 reasons why I cant have one,.....LOL
I guess its all in what your looking to do with it,....

Hey jmbear! What? I can't take my carbed stock 80 inch Evo on trips? Dang, wish someone had told me that before it hit 130,000 miles!
S&S Evo. Better quality, more reliable than HD Twinkie-motor.
But if ya just gotta have a Twinkie, then get gear drive cams, not the stock "We're in a continuous destruction mode" chain drive "Gee, why does my timing vary by 3 or 4 degrees" EPA mandated quiet POS.
