its a lazy ramped cam, made for upper rpm power 7000+ rpm. Jus another track only cam.
That 88* intake valve closing is gonna need about 12:1 CR. That means the piston is way up in the cylinder before the intake valve closes.
It's not gonna build power til late into the rpm.
If I was FORCED to use that cam, I would make dam sure the t/c or clutch was stalled to 4800 rpm. Any thing less, and that cam will not pull up outta the hole.
It's gonna be very easy on the valve train, but......so are stock cams.
The Dyno Cams cm grind and that cam would be very close in performance.
Learn to read a cam card. What the numbers mean.
If you add the intake open, and intake valve close together, then add 180, you will come up with the advertised duration. Same with the exhaust side.
That cam has 318* advertised duration. There's only 360* in a circle.
That means that intake valve spends alot of time opened, and needs a bunch of CR and rpm to make it work like it was designed.
The BMJ cam has around 282 advertised duration, the BM cam has around 295.
Both of the isky cams will pull harder up outta the hole, get to max rpm in a shorter distance, and not need crazy CR to make em work.
Heres a ECCarbs cam card with advertise duration numbers and .050" numbers.
Do the math yourself and learn how to read a cam card.
Any questions, jus ask.
Here's Dyno Cams card for the cm-grind, advertised specs. It's very close to the RPQ cam.

Here's some more math for you. Let's use the cm-grind specs
Add the intake open and close together, the add 180, that gives you 321.8 * advertised.
Now subtract the intake .050" lift duration number (236.9*) from the 321.8*, and that leaves you with a difference of 84.9.
This 84.9 number is VERY IMPORTANT, to me. I dont wanna see more then 65.
This number tells me how fast the intake valve will come off the seat and how fast it goes back on the seat from .050" lift.
The smaller this number, the "faster ramped" cam it will be.
The ISKY BMJ cam is around 50-55 difference in advertised and .050".
ECCarbs has fast ramped cams. Some can be as low as 47. Fast punching, hard hitting, cams in the whole powerband, but can be hard on the valve train. I don't recommend them for beginner builders.
Dyno Cams BP2 grind is a fast ramp cam.
Do the math, you will see.

If you jus learning cams, I suggest you stick with the stock cam for now. Get the CR up to around 10.5:1, add a pair of 1.3:1 stamped steel ratio rockers and 22# springs.
The extra pressure and ratio rockers changes the way the stock cam works. It will come on faster, and rev up quicker and higher.
Jus my 2 cent, good luck, learn, and have fun,
