pro series rockers

has anyone ever hear of or used pro series roller rockers they are stainless and a full roller and was wondering if anyone knows anything about them tried finding reveiws on them but cam up with nothing

i was browsing around on ebay and found these http://www.ebay.com/itm/330668712289?_trksid=p5197.c0.m619 they look alot like the crower rockers seen here http://www.summitracing.com/parts/CRO-73615-16/?rtype=10 the price has got me interested in them for a mild stock 429 and was thinking about trying them but i am not sure if i want to be a test pilot for them i dont turn more than 5500 rpms though and again the price has got me thinking it says in the add that they are made by a co. that they cant say the name of and are lifetime warrentied

The ones on E-bay are 1.7, I believe those are Chevy's, it also says they "FIT" Ford, does not say they are made for Fords.

The ones at Summit are 1.73, and say they are for Fords.

If you want the full lift of your cam, check your cam card and see what ratio it says to use before you buy some.

Also would not hurt to do the math on the cam cards. (Lobe lift x rocker ratio = valve lift) I had an ISKY cam in my first engine, the cam card said 1.7 ratio, so thats what I put on. After assembly, I did not have the lift at the valve that it said I should, short around .060. After doing some figuring, we figured out that the lift and ratio I had was all I was going to get at the valve. Called ISKY tech and he said that I needed the 1.73 to get that lift. Told him their cam card said 1.7, he said I was reading it wrong. Faxed him a copy of the cam card and then he said sorry, it looks like we mis-printed it.

well you seen something that i didnt it says in the add listing that they are 1.73 but then later it says 1.7 well i think i am going to call them and find out were they are made and what the ratio is before i decide to buy them thanks for the input on this

I'd find a good set of used cranes, ford motorsport, harland sharps, scorpions or similar before I'd waste $$$ on those.
