Lunati pistons?

[Fox_hunter42]

I had these pistons given to me and need some specs.
1318D5L5
1312D2R5
I'm assuming the L5 and R5 mean right or left. I have both in both sets.
Any info greatly appreciated.
I tried Lunati website and found nothing

I think they were actually made by Wiseco. They are no longer offered that I know of.

Both part numbers are 23* pistons.

that's a start, I really need to know what they fit, rod size, crank stroke etc.
Thanks

Call Lunati...

[Fox_hunter42]

I will if I ever get off work during business hours. Bad part, they don't sell Lunati pistons anymore. It's Wiseco now

I don't think Lanati ever made the pistons. I think they contracted with Wiseco to make them. Might call Wiseco and see what they would know if you strike out at Lanati.

Might also try somebody that has older catalogs and see if they can dig up a 200-2002 book, I think they stopped making those in 2002 if what I found was right. I don't have any books with them in there that I can find.

Doesn't sound like they are worth the trouble. I am short a piston on both sets and if I can't get a replacement they are junk. I believe they are for a Chevy 360, 6 inch rod, 3.5 crank, .060 over.

Single piston from Wiseco will probably run $125-175. Still a cheap set of quality pistons.

I would go direct to Wiseco and talk to them. They may want you to send one to them to copy.

You can measure the pistons and find their specs. In a SBC you are attempting to acheive a 9" deck height. You can do the math and figure out what they fit fairly easily. DH=Rod Length+Compression Height+(Stroke/2). So if your compression height is 1.56 then it will fit a 3.48"/3.5" stroke with a 5.7" rod. If it is 1.26" then it will fit the same with a 6" rod. If it is 1.125" then it will fit a 3.75" stroke with a 6" rod or a 3.48"/3.5" with a 6.125 rod. Hope this helps. You could possibly find another with the same specs and get them all balanced. Or you could build a 4.3 V6.

Make a nice 4.3, LOL
Im pretty sure they are .060 over, 350 for a 6 inch rod, 3.5 crank. I'm sure they told me it was a 360 motor, not a sprint motor.
