is the edelbrock performer rpm cam any good, and would I need valve springs to go with it. any info or experience with this cam would be helpful to know. thanks in advance.

 

Edlebrock says stock or their springs. Summit says you must replace the springs.

FWIW I would replace the springs and upgrade the valve seals while I was at it. This cam is good up to 5500 rpm. You think your old stock springs will hang on for that? Stock these motors probably never saw 5000 rpms.

What engine are you putting this in? What compression ratio? Headers? Performer intake or other fine brand?

Being a long duration cam compared to stock, it isn't going to work to it's potential in a stock low compression 360 or 390.

 

It would be going in to a 390 .040 over, cr is about 10 to 1, no headers yet but on the list, my heads have had some work done, and the cam i was talking about is edelbrocks 1500-6500, the vibe i'm going for is street truck

 

My current cam will do 5500 but its been the motor a long time i do have the performer 390 intake, if i do go with the bigger cam id get the intake to match

 

Go to the "search" function above the forum threads. Select "Advanced Search". Put the word "cam" in, and search the FE forum. You will find a ton of threads, and more than one like this one:

Stock springs will coil bind at .500 lift, the cam your looking at has .572 lift and must have matching aftermarket springs. For a street cam I'd look for something with .550 lift or less, high lift cams are hard on springs.

 

Comp 270s or 268h are highly regarded on this forum. As are very similar grinds from a lot of manufacturers.

 

with new cam ALWAYS new lifters and springs . better safe than sorry over a little $

 

can't believe no one asked this yet
what are you doing with truck ? hauling stuff or weekend toy ?

 

Careful reading will reveal:
