Huh? The sewing machine noise in inherent to the car... you can quiet it down w/ full roller rockers and using a pushrod checker to get the correct ones to set pre-load.

Do you have a coupe or Z06... even a stock Z06 sounds close to that... they all do it. You're hearing valve-train and fuel injectors.

That's the price of a bigger cam. After a few weeks of driving you don't even notice it anymore and you'll just love the extra power. I think we all hate that noise after a head/cam job and question ourselves, but it's all worth it!!

I run the Cadillac Racing lifters with .110 wall Trend pushrods, Comp 921 springs and a 234-240 112 XE-R cam and I have no valve train noise at all.

My $.02

Not necessarily true, im running the MS3 with LS7 lifters, stock rockers and 7.40 hardened pushrods and i have 0 sewing machine noise, if they are properly torqued to GM's sequence i have never had any noise problems.

That's my engine in the LINK..I have the caddy race lifter, 7.425 comp pushrods and Harland roller rockers torqued to 22 ftlbs as recommended by GM.

Here is the way the car sounds....

TSP should have the Trend PR's

fyi: LS7 lifters are the same as LS2, they are also the new replacements when ordering LS1/6 lifters

Do you believe the Trend pushrods would be better in holding down the sewing machine sound then the Comp pushrods?
Also have you been successful in stopping the sewing machine noise after a cam change? If so how?

Thanks

Longer pushrods - use 7.425 instead of stock 7.400

But check your P2V first

+1, sounds almost exactly like my Z06. If you think that is loud, you'd HATE my 77 camaro.

Long tubes + cam = sewing machine

Get used to it and learn to enjoy it or go back to stock. I love the sound!
