Theoretically, it should boost the mid-range power a bit, which is where you want it. Peak numbers may not be much different though. I didn't realize those blower cams were at a 115 ICL. 108 to 115 a really big difference.
Weren't you trapping like 110 mph with those cams though? IIRC, you didn't have any major weight reduction or anything crazy did you?
Also, is the 109 ICL a misprint on your part, or are you doing that to gain a little more clearance?

The highest I ever trapped with the blower cams was 109.8, but I have also made trips to the track where I only trapped 105-106, so I don't know if there is something going on with the trap clocks at my track or something.

That was a typo on my part. The cam card actually says to install them at 108.5,* but either way, it should be a decent difference going from a 115.

BTW, you do know that clearance will be really tight with those cams right?

Yeah, I'm definitely going to degree them and check for PTVC on the install. I know many guys just throw them in there, but I prefer the peace of mind knowing that I'm not gonna bend a valve. I also know the cam gears as well as the cams can be off a few degrees too.

I can't believe nobody even made the guy an offer. I see guys spending over $400 on used cams like comp 270s and stuff. They were up for a couiple weeks before I even posted I think.

Interesting note.......This is one of my cam cards......and the second is a buddy with CMS Stage 2s on another forum. The ones I have would have to have been ordered before his. I wonder why the ICL and LSA are off my a half of a degree.......JIM, where are you?

Heres a stupid question, I never had expereince building a mod motor just the old pushrod engines. When you do a cam swap can you just re-use the upper cam brackets? Id imagine they serve kinda as the bearings? Do you need to get anything machined? Or can you just bolt them down?
