what abou the 106400 and 500? piston to valve issues?

it cost alot for a cam set so just curious if going a little bigger would be better

Bigger is not always better... There are compromises to be made when going with long duration cams, like a loss of low-mid range hp and tq for a that extra power up top. There are also losses of upper rpm power when going with shorter duration cams. Most people would benefit from cams that provide the highest "average" power throughout the rpm range that the engine operates. I dare say that most people buy cams because of their long duration, percieved benefits and lopey idle.

I had someone contact me regarding PTV contact with stock pistons and 106500s just a couple days ago. This is not the norm though as I've installed them in a motor and know of three others that have done so also without any problems (all B headed motors with short runner intakes). I do not recommend the 106500 for a motor with C heads and stock intake. The 106400s are about the most aggressive that I would recommend, but shorter duration cams would make more average power...I know, everyone wants high peak numbers.

so how hard are they to install? I was thinking about buying dans but i want to install them myself. Is there a place online where i can get all the torque values and is there anything else i would need special for the install? Also does the front timing cover need to come off? i have never installed cams before so...

Thanks

If you are buying Cobra cams, you will just be changing the intake side, so their is no need to take off the timing cover. You will just have to pull the valve covers on the passenger side. On the driver's side you will have to pull the hydroboost assembly in order to get the valve cover off.

so i was just reading.... so does it have to be degreed? I was reading some older cam threads and its sounds like you just have to mark the srocket's and chains? is that right?

[PCPRO]

I lined up the dots on the sprockets and installed them by the keyway, which is "straight up" & didn't degree them.

ok cool. Thanks. I'm sure i will have more ?'s when i take it apart. I'm not doing the install till next month. I'm just doing all the reading and trying to see what stuff i need 1st. I don't need and special tools right? What are the torque specs? or do you have a link where i can get them?

thanks,

Bill

Buy yourself a Haynes manual, you'll get a lot of use out of it.

Thanks. I think I'm going to get one today. So i can read up before i tear it apart. I like to do all my work myself and plus I'm poor lol. I also have a few friends that will help but.... they are chevy guys.

I got all of my torque specs from the Sean Hyland book. Also, for anyone looking for a set of new FR500 cams, there is a set for $530 shipped at www.svtperformance.com in the classified,cobra/engine section!

I would NOT use the Hyland book for torque specs, it's loaded with bad torque specs.

i was looking at the haynes manul online. it says 94 to 04. is that the right one? it seems like it should be from 96 to 04.

Only you can answer that question. It all depends on how much power you want and how much moeny you are willing to pay for it. Going with aftermarket cams that don't require springs would offer some savings over those that need springs, but you'd still spend over $1k.
