914World.com _ 914World Garage _ Holy Crap! my pistons are sticking way out the bore!

Posted by: Mark Henry May 19 2006, 02:08 PM

I bought Mueller's engine project (that he got scared of and bailed) that uses a 78mm crank and 94mm T1 Cima B pistons. This what I found upon mock-up!

Are you gonna need longer head studs, too?

Posted by: groot May 19 2006, 02:18 PM

That's truly insane............

Sounds like you need some custom pistons that move the wrist pin up for that huge crank.

ARP head studs are longer than stock....Ihope they are 3/8"+ longer. burnout.gif

BTW I did know this and it's not a huge deal....

Next I'm going out to mock it up with an 80mm crank with shorter chevy rods to see what that does.

A little better with the 80mm chevy rod crank... I now have .030 deck....of course thats with .300 of shim under the jug.

Hi Mark

What your goal on this motor? Looks realy interesting !
Side question...when I hit your link to your webpage, it gives, I am guessing, your list of distributors? If I need to get some parts in Canada, how would I go about it?

Back to your motor, what type of head work are you going to do/use?

Later

Mike made me an offer I couldn't (but maybe should have, lol) refuse.

Can we say boost. happy11.gif

The site is all screwed up...most likely hacked.
We're trying to fix it.

Call me at 905-797-2677 or mhenry69@sympatico.ca

With .030 deck and boost I hope you got some big combustion chambers. Yikes, the spark plugs gonna act like a glow plug.
