Default Help deciphering cam card please

I wish I had a scanner

Lobe Seperation 110
IN OPENS 4* BTDC
IN CLOSES 36* ABDC


EX CLOSES -4* ATDC
EX OPENS 44* BBDC

CENTER LINE OF IN LOBE
106* The above center line will make this cam 4* advanced

The cam is supposed to be a 112 LSA cam (220/220/ .581/.581 112) lunati grind from TSP

Those cam specs are saying it is a 110' lobe center. The card usually list the .050"/.006" specs also. The timing all points to 110'.

Well according to the timing events it is on a 110lsa and on a 106icl. So no it is not a 112 anything(icl or lsa).

Alos, for those specs to be correct, it should have the exhaust closing at -4* ATDC not +4*.

That was my confusion... I ordered a 112LSA from TSP and received a 110LSA in the mail....

Now I am wondering whether to just toss the cam in tomorrow (It looks to be raining so I won't be working) or to send it back and wait another 2-3 weeks for the proper cam to arrive...

Anyone ever run a 220/220 .581/.581 110LSA cam before? I tried searching and not many people run a 110LSA

I'm mostly worried about:

A) Whether a 110LSA/106ICL will be more prone to clearance problems (PTV, I have stock heads)

and

B) how much higher will this cam shift my power band

Thanks

It should bring your peak lower in the rev range, not higher. As for PTV, someone else please chime in.

PS. That cam may not make too much power over your hotcam. Why didn't you go a bit bigger?

I would return it and shop somewhere else..no reason for that bullshit to even happen. There are tons of cams off the shelf...and everyone should send you what you ordered.

S**t happens. I've had nothing but good experiences with TSP. I'm sure it was an oversight. I would get the cam you originally ordered. IMHO its worth the wait to get what you really want. You may end up putting the 110 cam in and regretting it for months. Call up TSP and see if they will ship you a new cam overnight. Good Luck...

IMO when you advance a cam and gain power- the cam was a little on the large side to begin with. If you retard the cam and gain power- the cam is on the small side.

Well its not TSPs fault, at least I don't think so... They don't even market a 110LSA, they have their cams ground by lunati. My cam was drop shipped from Lunati and never went through their shop.

I'm gonna put the cam in today. Its not too much work, and if in the end I don't like it, well, I'll try something else.
