Hi guys,

Has anyone recently tried to build a +0.085" or +0.104" Bore Engine Lately?


If so where are you getting Pistons?

THe Wiseco Catalog for 2018 only Lists +.025" and +.045" Pistons.

Whaddya think?

is it time for a group Buy to get some +.104's back on the shelves?

I'm up for some "+.104" pistons if we can get them with thin racing rings.

I decided to go with the .085's to have just a little more cylinder wall thickness and to allow me to bore to .104 in the future. Ryan did the same with his race motor. I think a group buy would be good. I'm not sure I can afford them right now since I just retired.

I got mine from Ross, but they are custom. Ross does nice work, but ask prices BEFORE you hit the buy button.

Hi Dennis,

Can you say a little bit about why you went with Ross? I am looking at custom pistons for a new stroker motor. It will be a "Lou" motor, meaning I will drive it 1000s of miles on the street, make passes on the strip, and run some twisty stuff.

Thanks!
Lou

Mine are +.100" flat top, thick deck forged nitrous pistons for a 6.7" rod with the pin moved down .100". It has a thin race ring package and a Slant wrist pin. On an uncut block they should be about -.080" in the hole and give roughly 9.5-1 compression.

It is a standard Chevy 3.5" blank and would have been $60 each, but for some reason they hit me $40 each for moving the pin.

They are absolutely beautiful all wrapped up in the box.

We used Ross because that was who Mike was using at the time. I am guessing I got them 10 years ago.

Does anyone have a current contact at Wiesco we could contact. I know Brian Nutter worked with Rob on the first round but he left there shortly after that. Seems like maybe he sent me a "Deptartment" or group within Wiesco to ask for after he left. That was on my old computer though and I will have to do some searching to see if I have it still.

Sorry to divert the thread, but would anyone interested be in some 1.2" compression height pistons likely in 3.504" bore? I am thinking of getting 2 sets made for 198 crank + 170 block and stroker 225 projects I am working toward. Not right away, but down the road a little...

I am likely going to use Slant 6 pin size, but I could switch to another size as I will need custom rods anyway.

Thanks for the Wiseco info, Rick!

If you go to a smaller pin like a Ford, you end up with a lighter pin, and a touch more room on the piston for the ring pack.
