S.B. Roller Rockers

[Swinger69]

Just spotted shaft rockers from ProForm, they are almost half the price of other brands and are sold complete with shafts & hardware.
Price is right but how is the quality.
Has anyone had any experience with these.
I have a 360cu with a 275 extreme high lift Comp Cams grind with 525" lift & I probably wont turn it past 6000rpms

If you are not going to spin it past 6K, save your money. Set up the stock units properly and buy Dons new ignition system for 1/2 the price. It will give you more hp than the RR will. M2CW. (ps I have one on order).

I wouldn't use aluminum rockers on the street, especially if you drive it often. the aluminum has a short fatigue life meaning they will break, and with a lower priced rocker, probably sooner than later. If you are using stock rockers, you'll probably need rocker shaft spacers with .525 lift cam. If i was you i would use the adjustable ductile iron rockers from crane or MP. very durable and last forever. If you have extra dough the comp cams promagnum settup is best, strong and light.

All ProForm is Chinese, if you want a Chinese car get a Lata..no wait that's Russian....do the Chinese make a car?

1322-16 Comp Pro Mag arms...best bang for the buck $419.95 freight included anywhere in the lower 48

I think i'll take your advice & go with the Crane ductile rockers.
I kind of knew what your replies would be, but I guess I was hoping this would be an exception to the rule "you get what you pay for". The Comp rockers are over $600.00 Canadian, not in the budget & Santa can't supply them (he said they were on back order).
Thanks for the advice.

I read somewhere they make Buicks in China, AND engines for USA cars. Someone correct me if I'm wrong.

You need to do some current exchange rate pricing - as in pay the $US price and use a credit card or Paypal. Our $ has been pretty much at par for the last 6 months at least.
Re: acr's comment about Chinese Buicks - correct. GM has been building cars in China for a long time. And they are not alone. I'm sure there's some Chinese content in some import cars. Not to mention your i-phone, computer hard drive, t.v., stroker crank, etc, etc.
