RED/GREY PISTONS

[EK DAZ]

Hi Guys,What is the difference between 138 red pistons and 138 grey pistons. It sounds like the bores are the same (11/8) Would they be interchangeable?. Regards Daz

[Dr Terry]

No, the bores are not the same.

A 138 Grey has a 3.00" bore & a 3.125" stroke.

A 138 Red has a 3.125" bore & a 3.00" stroke.

It there a piston from another make & model vehicle that will fit into a grey motor?

Apparently EIP Vauxhall will do the job, but I guess that they are as hard to find as Grey motor pistons.

Try nason engines parts for pistons ...they have grey motor pistons and are very reasonably priced ....I bought a set of oversized pistons 3 and 3/16 for my grey recently ...I think about $300.00 for pistons,rings and gudgeons ..I hope this helps mate

DAZ, what the hell is a EIP vauxhall???

I think they were made from 1954 thru to 1957. The Velox was the six cylinder and the Wyvern was the four cylinder and a few were called Vagabonds ,which were the convertibles, which we never got over here, but I have seen a couple in Aussie, Daz
