Two years ago my daughter installed a GM Performance 385 Fast Burn crate motor in her Monte Carlo. Now, she has decided that she absolutely has to have a GM Performance 350 Hot Cam Kit 12480002 which includes a 24502586 cam (she is expecter her daddy to do the installation work).
I have no idea if this is a good choice for her. The only cam swap I have ever done was in my LS1 but it was easy to find a ton of info on here about what cams are best suited for various situations by using the Search feature. But for her, I dont know of a good place to get advice.
The car is NOT a daily driver. It is mostly is driven to and from the track weekly -- a distance of about 5 miles. She also drives it frequently on weekends to car shows and to local hangouts but rarely more than about 15 miles away from home and rarely on the open highway. So what she wants is fairly hot cam for the track but that is still streetable.
Any advice? Also, am I safe from needing to worry about any clearance issues or other fitment problems?
Some specs: The cam as it came from the factory is a Hydraulic Roller Cam with .474/.510 lift. Duration @ .50 = 208/221. The GM Performance Hot Cam is .525/.525 lift and duration of 218/228. LSA = 112. She is looking at the kit which also includes aluminum roller rocker arms with a 1.6: 1 ratio.

How about an Edelbrock cam. 234/244 .488/.510 on a 112 Lsa with 1.5 rockers. I put 1.6's on mine. I have it in my 327 with fast burn heads and it preforms great. Awsome mid range and top end pulls like a ****. The bottom end isnt as great though cuz i dont have a stall and i think the heads and cam are meant for more cubic inches. That's why i am currently taking that cam and heads out the 327 and putting them in a 383stroker that i am building.

hello all new here was doing a search and ran into the same thing i want to do to my enine.i have the same engine in a 87 montecarlo ss and i wanted to add a hot cam kit which will put it at 425hp. but im looking for a streetable cam that will turn some heads with the chopy sound on the engine and of course the hp. some people tell me to put more duration in it if i want a chopy sound. i was looking at that hot cam my self and another cam down the list p/n 12370847 hyd roller I:234 E:242 @.050 lift I:539 E:558 lobe 112
but i dont know what horse power this will give and torque or if it will give me that chopy sound that will turn heads as soon as i pull up ??????

I:234 E:242 @.050 lift I:539 E:558 lobe 112 1.6 rockers
this is the gm cam i want to go with now. it will give me 465hp 410tq but now i need a set of springs that will clear perfect in the fast burn heads.
i hear that the max lift clearance is .525 on the heads. but they say i have to do some grinding on the head to be able use the 1.6 rockers and a lift of .595 or so lift. the reason why i want this cam is because Scoggin Dickey
has this cam in the zz465 same heads and block just diffrent springs but i think it has work done to the heads. anyone have an idea what springs they
have and if they did any work on the heads.???????
