New here and need some help please.

Post by GeorgeS87 » October 6th, 2019, 1:22 pm

:) Hi all, I was wondering if any one knows the measurement of a Stock 87 YJ 4.2L combustion chamber (cc's) the motor had the Carter BBC 2 barrel carb when I got it. I'm wanting to rebuild the engine but the company I'm ordering from needs that measurement and I can't tear down the motor at this time but want to receive my new paid for pistons. Any help would be much appreciated!!! :rockout:

I Don’t Know much about 258 Specifics, but I’d recommend Sourcing that information through a head casting number.
I’ve seen numbers referenced as high as 71cc and in the low 60’s.

Sorry I couldn’t be of any greater help.
