Alright, armed with other's viewpoints, and continued research, I made a decision based more on my riding style, than anything else. From what I concluded, it's going to be the 27! Thanks to all! I'll write back a bit later to let you all know what I think about this new cam. I have to admit, though, if it wasn't for that damned INA bearing, I probably wouldn't have even monkeyed with the bottom. See my new thread regarding OIL! EEEGAD, not again!!
Another oil thread??? You do realize that is grounds for hanging around here right? LOL

Hi guys!
Another EV-13'r here :-)
A few months ago, after reading all I could find about the matter and deciding, I got installed the EV-13. Combined with the Mikuni 42 I had for many years, new hi performance Crane hydraulic tappets, new pushrods and Torrington bearing, I got finished the known Joe Minton's "pass a truck combo".
Can't be happier with the response, the bike it's a different one, gained lots of low/mid power, great for 2up and still gets fast in a hurry when needed. The cam starts working right from the bottom, but I can keep up without problem at lighter speeds when riding with groups of different modern HD engine bikes, usually at 80-90mph, or more.

I've got an EV3, Edlebrock Intake, Mikuni 42 - '88 FLHS - It was this way when i inherited by bike, so i don't have any comparison, but I can keep up with the 100" Revtech I ride with, so, it's doing great in my book!

3.34 gearing would still be a candidate for a 27 or 3020, it will just pull a tad bit harder. With stock type compression, a later intake closing and higher duration cam would be hard to overcome a low rpm soft spot even with lower gearing so cam choice is still narrowed down to a early intake closing cam like the 27.
With a compression bump then choices open up as compression will get you through the low soft spots and then hit yeehaw area with bigger cams. I have 89" with compression, 3.59 gearing and can get away with a late intake closing cam but didn't, my riding style has alot of backroad accelleration with my riding buddies so I opted for a Woods W6H that allowed a earley rpm fork stretcher that pulls through midrange and doesn't fall off up high, the Woods W6H design for a big cam is earlier intake closing, lower duration and high lift.
The moral to my muttering is the veterans on here always mention riding style right away, personal experiance of matching componates to riding style as I made bad cam choices during the learing process such as too much compression and earley intake closing cams

Should have reported back sooner, but too much fun ridin'! Anyway, I went with the 27. Been in about a month now, and the best way to describe it with my stock carb and motor is it's like a passing gear that I didn't have with the N cam. Didn't really notice from a stop any difference, but that first vehicle pass was like, "Wow, it's there". Reminded me of my '60 Pontiac with it's 389 4barrel when you stomped on it. Incredible quick response! Thanks for the all the help. Oh, by the way, the original INA bearing was in excellent condition, and may have gone another 22k, but I wanted no more chances with that, and now I'm riding on with the Torrington, which was the original reason to get into the gearbox.
