I spoke with Fred tonight on the phone. True gentleman and incredibly knowledgeable. Great to share experiences with him. We have a set of 98mm on order for a yet unsold future build.

Cheers

I am ordering 10 sets of pistons.SS 66 X 95MM.66 X 98MM.5 sets of SS 70.4 x 98mm.3 sets of 3.2-3.4 98mm.These are all sold.These will be done in the end of October.I will make another run and at this time they will be done in the middle of November.I need 6 orders to commit.Ciao Fred



The problem here is the supply chain.In the old days it was2-3 weeks and if you prepaid with wire transfer less than 2 weeks for 5 sets or more.Those days are gone for now.Thanks for looking.Fred

[Jeff Alton]

Can't wait for our set Fred!

Thank again for taking our order and the time you spent on the phone with me.

Cheers

Bump & the Filet Cheese steaks were killer.

I too, am excited to get the 95s for my SC case, Supercrank, short stroke 2.8 build! I finally got my longer rods so I can think about getting busy. Still, knowing me, October delivery should be no problem!

[faapgar]

I have 10 different sets that should be done by around the end of September with this current order.Fred

Hi Fred, are there still gains to be had with dual plugs? If so then how much? It seems that with your design the flame front doesn’t travel as far and the pocket creates a cleaner burn so single plug should suffice.

[faapgar]

You can run a higher CR than normal with single but twin plug is still safer being more retarded.With 91 Octane twin would be better.

Friday bump.

A few more pics with the bottom of the valve pockets shaded in to better show the shape.


It is a unique design which promotes more complete combustion and increases flow.I have a CIS model with shallower valve pockets and the flat area of the top center is dropped even lower to increase air flow through the head.Great benefit to run a hotter cam and retain the simplicity and reliability of the CIS.Very California friendly.Thanks for looking.Fred

Very cool design. It's like the opposite of the "peanut" heads that Henry posted a very long time ago.

Old school with a twist

I guess I need to save my money for next build.

[faapgar]

I can make different sizes suited to whatever CR you need.I just had a request for 85mm for a 2.5L.No problem.Welcome to the new modern piston which out performs all that have preceded this design.Thanks for looking Fred

[jpnovak]

HMM. I have a 2.5 on the build slot. 90x66. Currently planning 10.5:1 twin plug.

What CR could I get away with for single plug?

Could you describe a little about the limits of CR and single vs twin plug?

[faapgar]

Just ordered a set of 100mm.Ordered at 11:1 to end up at around 10:5 CR after the valve job.If you do a valve job on an SC and reface the valves which drops them a little lower your CR can change from 8:5 to 1 down to 7:8 or 7:9 to 1.Always CC your motor when you take it apart.It may have had a valve job already.I have seen race engines that were 9:2 to 1.

OK Fred, you and everyone else here know wayyyyy more than I. I have a stock 3.0 SC that need a top end. Which would I order and/what benefits would a stock motor gain? It sounds to me, a novice here, that you guys are all talking about hot rodded motors?? Or, what mods would I need to make them work with my engine? Cams etc. I know more that you want but I have to know what to buy.....
Thanks
Sean
