what exactly can i expect out of 288/282 cam regrinds?

[winsauce]

in attempts of broadening my automotive understanding ive made a new addition to my mod list. yet again raped the wallet like its my prison bitch and dug the rabbit hole just that much deeper. truth is, i dont know much about cams and i want to change that.

i want to know what these cams will do for me as far as usable power band? can someone translate these technical measurements for me, and more importantly show me some good threads i can learn from?

and yes i know they will not fit in the stock head or play nice with stock valve train. Im getting adjustable cam gears, dual valve springs, and 1mm os valves, what else do i need?

should i be worried about this ending up being an interference engine with the increased valve lift, os valves, and higher compression weisco pistons? and is that particularly a bad thing?

heres the cam card i was given

Ran a pair of 280/351 thou lift sticks in my 7M, they were only 226@50 though so not nearly as aggressive as the ones you have, tuned right it idled like a kitten and made good power to 8000.

YES it is now an interference engine

Titanium retainers and tuning + a nice valve lash adjustment.

Hahah freaking ij!!! Xd

 

[winsauce]

thanks guys, like always excellent info...

only thing left is to start hogging out the head so they fit.
do you have any before and after photos of the top end of your head IJ?

 

[IJ.]

Umm mine went straight in no reliefs needed.

 

[winsauce]

interesting... the guy porting my head said i may have to open up the head so they will swing with the 10mm lift.
cams just got shipped today, so pics on the way

 

[IJ.]

I think 10mm is where it's "close" depending on the head casting, mine were only 9mm lift so plenty of room to swing.
