Does anyone know where I can get the specs on stock TC 88 cams? I've been reading through the threads about 95" builds, been in touch with a couple of the answer guys on here, and got some advice. I was originally planning to go with the "winter special" Stage 2 big bore, but told the dealer I wanted Andrews 26G cams instead of the SE 203's in the kit. Stealer told me he looked up the specs on 26G and it's within .001" of matching the stock cam. I'm finding that a little hard to believe, so I wanted to compare the numbers.

I've had a few discussions with him about this deal, and each time I'm a little more leery of having them work my bike up. I'm leaning toward doing nothing at all, and come spring, cya!:xhere:

'04 FLHTCUI
Ride 2 up about 50%
Bushtec trailer

Lookin' for max torque!
Here is the essential stock cam data............

Stock (A) 02/38 216 0.473 0.072
Carb....... 36/04 220 0.473 0.110

Stock (B) 02/34 216 0.473 0.087
Injectors 36/04 220 0.473 0.110

6* of overlap and the efi cam intake closing is 4* earlier.


Here's the TW21............

TW21 10/30 220 0.498 0.134
.........40/08 228 0.498 0.121

Real early intake closing, 18* overlap, more lift than stock.


Here's the TW26.........

TW26 11/35 226 0.490 0.138
......... 41/09 230 0.490 0.112

Moderately early intake closing, 20* of overlap, longer duration, slightly less lift than the 21.


Here's the TW37............

TW37 18/38 236 0.510 0.174
..........46/14 240 0.510 0.148

Intake closing at 38* for better broad powerband across the rpm range, 32* of overlap, longer durations, better lift. This cam will have the low end torque and the upper end will pull right to the rev limiter. Probably the best all around cam in their line-up.

Hope this helps!
