They yield around 8.5.1 with a steel gasket and closed chambered head. Could I use these with a Blower or is there a technology that I am not aware of when it comes to piston use with a Blower. I do not know a lot, if anything when it comes to building a Blown engine. Thanks. RS23L7 4-Speed

I'm not familar with that piston number, is it a cast piston or forged? I would not use a cast piston in a blower motor Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I would not use a cast piston in a blower motor just a question regarding this, how thick does the piston top need to be in a blown motor? sorry if it was a highjack just got a feeling that question may show up anyway

I did burn 3 up, my fault I forgot to turn on the eletric fuel pump. put well over 5k on it and countless runs before I sold the car. 5052066-sc2aa.JPG (193 downloads)

Thanks. i would have to say .200 from the top of the piston is safe for the first ring.my comp HT on my piston is 2.050.i have had my pistons out after running 8lbs for 3yrs and there is some color on the side of the piston to .150/.200.my bore is tight at.006 and the top ring gap at .023[hellfire speedpro]my piston thickness just over the rod i would say is .200. i have wiseco K373A3 w/open chamber 346 heads.8.8cr

So many people build mix and match bargain engine combos then wonder why they don't work or fail. Build a engine combination ( especially a supercharged combo )with a goal and result in mind . If you don't any money you thought you saved will be lost on buying everything twice. 6.50 @ 226 MPH 4.25 @ 186 MPH https://www.youtube.com/watch?v=YX86DHGKBo0
