I have a question concerning comps 282hr cam......

is this cam too big for the street?????

i will drive the ta on the weekends and whenever i want but will this cam be too big????

 

I'd have to say yes, infact i was lookin at the exact same one for i buildup I was lookin into........I called up Comp Cams and they recomended the one step below that, the XE272? I beleive, and so would I.........for the street atleast, the XE282 startes makin power too high up in rpm's

 

I have one in a 400, it's alot of cam, about all a 400 can stand on the street; probably a bit much for a 350.

The XR276HR would have a little better manners. Or, you might want to look at their "306" grind, it's made for a heavily modded TPI but would be OK in a carbed application too.

 

Can somebody post the specs on that cam?? I have the XE284 cam in my firebird......not sure how similar it is to that one, but with 110 LS and 244 duration @.050 its still a really streatable cam. I drive my firebird pretty much everyday in traffic, only catch is that I have to have my idle set at about 1,100 otherwise it pretty much loses all braking vacuum when you stop real fast. It only makes about 9 inches of vacuum at 900 rpms and runs real ragged below 2,000, but MAN, when you get into your power band its friggin suck'yo'*** into the seat power! With a 5 speed its really easy to street drive with. With an auto I'd say you need a nice converter so it won't stumble off idle. It passes emissions too BTW.

 

As I said in the PM, I haven't had any problems with it on the street with my 350. I don't put alot of miles on my car but I've been in traffic with it and have done some cruises with alot of stop and go and the car runs just fine.

 

the reason i asked is i just downloaded a sound file of that cam and damn it lopes......... i'm sticking it in a afr headed 383 with stealth ram and 30lb ford racing injectors....... i hope it will run until i can get a chip burnt for it......

karp.... are you running carb or fuel injection????

It's alot of cam. Being a roller, it's a WHOLE LOT more than a flat tappet of similar "paper" specs; the lobes look like big squares compared to little pointy things on a flat tappet sitting next to it (XR282HR vs 282S)

 

heres the link to the cam... it may be the wrong cam i'll email him to make sure....
