Pistons with Teflon? And Rod Bolts?

Pistons with Teflon?

I have never run an engine with Teflon in the skirts, but the motor we bought has it. Some of the buttons in the skirts have come out and are gone.

My question is. Can I run the pistons with out them, or can I get new ones to put back in?
The bores look great even on the cylinders that are missing the buttons.

It is a 4.250 bore Hemi. There are no markings on the pistons to know what brand they are.

We also never had run Brooks 88 rods. Does any body know the bolt torque?

Thanks
Bob

 

save yourself a lot of headaches bob, if you hurt the motor in any way , just play it safe and replace all the rods,pistons, and wrist pins. the wrist pins are as crucial as the rods. its like the old fram commercial, "you can pay now...or pay later." as for the torque on the brooks 88's.... if the bolts have black washers they get torqued to 90 lbs... but if you didn't put them in origonaly.... replace them all.

 

Thanks
I will take that advice. How are you set up this year

IHRA or NHRA?

We still are running the Big dogg stuff with the Slow Mod

Hey I pull that trailer to texas and back with out a hitch
