That's what I run. When I bought my bike, it was a 2001 EGC with the MM injection. The previous owner had installed S&S 510 gear driven cams and the Harley programmable ECM (same thing as the S&S VFI). I put a V&H ProPipe on it and added the S&S VFI Autotune kit. Last winter I rebuild the top end using the S&S 97" kit, S&S 89cc Super Stock heads, SE 1.725:1 rockers on the intakes, S&S forged 1.625:1 rockers on the exhaust, billet rocker supports, S&S quickee pushrods, & S&S Premium lifters. I tried to break it in like that, but quickly realized that the MM injection wasn't cutting it. Replaced the MM with an S&S 52mm throttle body with the S&S tuned induction air cleaner. I tried tuning it myself for a couple of months, then I took it to Wolfgang Grasser at Mutant Motors by Wolf and put it on his dyno. He and I played around with the tuning for about half the day. I wound up with 105hp and 109ft/lbs of torque.
It started off as A cam swap with the woods TW6 then after we pulled Camplate we noticed 1 metal shaving Looked like a rod bearing it was Machine So i decided to do the S&S 97"big bore kit with 10.5 to 1 compression that way everything would be replaced I've looks at woods website with the cams it shows 100 /100 with stock heads just wondering if any one dine some similar

Client from Merideth NH, recently had us build a 98", with our Stage III Super Tour Heads.
While tuning that combo with a .585 S&S cam, DAS Performace, in Drakett, Mass ran out of injector at 119.7 hp.
Dan Thayer, Thayers Sales & Service, Corfu, NY, in the not so distant past, had another one of our 98"ers on his drum, with a Wood 8, OE t/body, modified,........115/116.

Agree'd. Even a VERY mild 98" should kill 100/100.just had a guy do 109/116 with. 570 S&S cams.10.0-1.and our street port headwork.also done many. 585/10.5-1 98"ers that will do just under 120/120
