Just wondering if anybody is using these cams. A nearby mechanic said he would swap me straight up for my 583s because he is curious also. I do believe S&S came out with these cams about a half year ago.

 

That .635?

Disregard.
No I don't use 103 cams. Sorry.

 

Trade them for the mr103. hp 103 is too much cam without alot of other mods im sure. You would probably regret the swap.....just my opinion ........

 

.575

Will p&p heads and t-body with cams.

 

that would probably compliment well. I just notices 575 vs 585 for the mr 103. Intake close is 50 for the mr which is what has me wondering if it would make an otherwise stock 103 soft on the bottom. Hell maybe your shop is onto something fun. Keep us posted. Im sure the cams are good just not alot of info to gather yet from people who actually have installed them. hope it turns out great for ya!

 

In what way would they be to much like to lumpy etc

 

Imo they may come on after 3000 rpm. Most people prefer the tq earlier. I have the mr103 cams and they work as advertised. So I would not hesitate to take s&s word on the performance of the hp.

 

The 583 is a very good bolt in cam and requires no bump in compression to perform well, has good low end torque through to midrange. The hp103 will require static comp of atleast 10.8:1 to make work with port work to the heads and then will come on from 3000 to 6500 rpm. Not for a stocker.

 

Hey thanks for the info bit late I already purchased them I was in contact with s&s before I brought they said it'll work so we'll see how they go I keep ta posted
