The quicker the torque comes on, the more of it that is manufactured, and how long it carries into the upper rpm range is EXACTLY what a man can use for a street Harley.
The 48 in one cam that'll do just that, for a plug/play application.
That S&S cam is a ****-poor choice. Don't know who at S&S would suggest that at the OEM compression ratio..........

Bigger is not always bigger. They have a mr103 that might work better. I was about to order a set myself until I decided to buy a new home. Looks like cams are on hold. Although nobody on the forum seems to have much experience with the mr103 one indy in my area said he liked it a lot.

Hell yes bigger is better...I wouldnt mess with a piddly cam that has less than .650 lift for a stop light racer..compression is overrated too.. 9.0 to 9.5 is all you will need to kick maximum *** with a .650 + cam. Make sure you get a go pro and video the red light race to prove it all!

I would go with what works great in your setup. The andrews 48 as hillside recommend is a great choice if not the best choice.. As far as bigger being better not so much I just had a friend build his bike with a woods 777 cam and talking **** and let me tell u he looked like a huge fool when my andrews 21 powered bike went flying by.. And he had a weight advantage.. That's a good feeling maybe he would have looked like less of a fool before he said I was stupid for picking a baby cam.. Whos stupid now

I have two other friends brothers and they have the same bikes there twin bikes setup the same.. They were fighting over cams one went with andrews 21 the other the bigger 37 the bikes are otherwise stock with just pipes.. The one brother was yelling go big or go home well he's not yelling that now as the big 37 cam he ran he said did nothing... He said his brothers bike with the small cam makes way more power...

1. The more aggressive the cam, the more OTHER, matching changes are required in the engine in order for the cam to do its stuff (compression, head work, throttle body, etc)
2. For street versus track, even for occasional street RACING, it's the AREA UNDER THE CURVE that counts, because you are not always "going" at high rpm, but rather often coming to a dead stop and accelerating from that dead stop. Most drag races on the street are short, rarely getting past 70 or 80 mph, which means half the race or more is spent running up through the rpm range in 1st. If the engine doesn't make power below 3500 rpm, the opponent with the fat midrange engine versus high rpm engine will win.
