Hello,

I’m interested in the piston set. Are they open chambered or closed chamber pistons. What is the best you can do on price?

Thanks,

Not sure what your asking here. Are you inquiring as to whether these are for an OPEN or CLOSED chamber cylinder head?
Can somebody else chime in here? Aren't the ZL1 / L88 motors closed chamber?

Open

According to a 1987 General Motors Performance Parts catalog I have: ID # 3947886 is part # 3959105 Piston assembly STD, 427 CID, Chevrolet 68-69 W/H.D. & Aluminum Block (RPO L-88 & ZL-1) 12.5:1 Open Chamber, Forged Aluminum, Floating Pin Design, Use retainer P/N 3942423 (I.D.3947886 or 3959108) I hope this helps.

Thank you BB Bill....

Your welcome, glad to help.

Open chamber.

1967 1st design L88 was closed chamber.

Thanks, Im looking for 1st design pistons that work with the 3919842 aluminum heads. It has around 106.8cc closed chamber head. I thought the combination could work one way, but not the other. I don’t think open chamber pistons will work with a close chamber head.

No they will not
