valve train noise with fm13 cam
valve train noise with fm13 cam Just how loud is it supposed to be to be exceptable?
I changed from the c1 to the f13 and it sounds nice but the valve trains sounds like a sewing factory is under the valve covers. Lots of ticking going on. I have not ran it very hard yet as I am not sure if it is right. It ounds like a solid roller setup with the amount of lifter noise .
On a side note, it drives as good or better then my c1 cam and not even tuned yet for this cam. SOunds great too.

i'm not sure what level of noise is acceptable,but when i went from the stock cam to the tr220,i thought it sounded like a sewing machine as well.are you running the stock rockers and lifters?did you check your pushrod length to make sure you have the right amount of pre-load?
I am running the same pushrods as I did wiht the c1 222/222/.566/.566 112 lsa cam. they are 7.35 instead of 7.40 and the cams are ground on the same base circle. I drove the car for a while last night and it runs great just louder valvtrain then I care for. I will take it by allen Monday and see if that is normal or maybe just needs the 7.40 pushrods.

You need 7.40 p-rods as aftermarket centerlines are smaller. By going 7.35 you are at least .03 too short and if you are running stock rockers, they are non adjustable.
Another way you could fix that is to shim the rocker stands by that much.

My heads are milled .015 and that is why I had 7.35's with the c1. We checked the pattern on how they ride on the valve tip and they looked great. I will get them checked to see whats up though.
Joshua, Went to track today and untuned shifting at the same rpm as c1 cam(6600) it went 11.56 at 119 .08 mph. and 11.58 @ 119.20 mph with a 1.63 60 ft.
It has much potential after tuning
This cam really does drive as good as the c1 with the tq down low. I dont feel that I lost any at all. It sounds nice to
I forgot , DA +949 feet above and a race weight of around 3,650 lbs
