Are there any benefits to having Ross pistons in new STOCK .30 over rebuild of our 409, with stock heads
Ross Pistons - Who carries?

A man of few words, I like that. I wonder...? Should I spend the 650.00 for these?.
ShowCars still lists their Ross forged pistons for $749
Just on Show Cars and it shows a set .30 over (20 lbs) for 649.00 I did see that these are about 150 cheaper, there must be a reason.? I tried calling Ross this afternoon, but there phone was busy, also emailed them. Just learning guys, thanks for the help.
The $650 and $750 ones from show cars are "off the shelf" Ross forgings.
I have bought several parts from Show Cars, but for the pistons I would order them through someone who can help you get them spec'd right for your needs.
Bore, stroke, rod length, 5/64" or 1/16" width rings, compression distance (deck height), compression ratio, dome volume and height, cam timing and valve relief depths, passenger or truck block, etc., etc. There are a lot of things that need to be correct to suit YOUR engine so I would not pay about the same price for an off the shelf piston as custom ones.
You can get custom ones to your specs for about $750, but then if you have them lightened you will end up at $900 or more. EVERYONE who has built a 348 / 409 highly recommends the lightening.
I paid another $115 or so for coated skirts. I wasn't planning on them, but at the time I was ordering I thought "at this point, what is another $100 or so?" Waited my whole life for this build....and knew I'd end up regretting it if I skipped the coating.
Jack Gibbs, Aubrey, Jim Richmond Engines, Day Automotive, can help you get the correct parts. I bet I am leaving a lot of people out.....my apologies.

KB is the cheapest by FAR! Diamond is NOT cheap. My fully lightened custom built Diamond pistons were ordered by Tony at Day Automotive and cost $1000
$1000.00 was what diamond quoted me over the phone for mine... I called KB and they only offered 348 pistons with the stock pin location. Since I wanted to use the longer rods, the Ross custom pistons from show cars seemed like my best option at the time...
Same here. I'm acquiring some parts for a 348 build and will be trying the KB pistons also. A buddy of mine used them in his mild stroker 409 and they were nice pieces!
I wish KB would start offering them for the longer (6.385") rods.
6.135 rods seem to work ok 
The K-B is a nice little piston as far as it goes.They are limited on sizes and compression ratios,and are not availeable in a "custom" form like the Ross,Diamond and others. As to the 409 ,they are only availeable in oversizes like .028,038,068 ect.,which as Buildit posted,makes for a better ring selection. As far as I am aware,the 348 is only availeable for the 4in stroker engine[it can also work when using the 409 stroke,and a 6.385 rod.].
