Default Re: What is involved to upgrade to a larger rotating assembly

...hey sleepy hollow ...I am your neighbor in hartsdale...

...I'm getting ready to do a H/C swap on my full bolt-on car in a week or two...

...i think the rotating assembly is straight forward if you buy the kit since it is fully balanced...all you do is put the rings in the bores and file them to the right lenght...everthing else is straight forward assembly work with a tork wrench,,,


...if you want to go really big, a 4.125 crank in a LQ4 iron block is the way to go...from my understanding, there is no available kit to match the 4" or larger bore so crank, rods, pistons etc have to be ordered separately ...this also means they have to be professionaly balanced by a machine shop...before installation...

...so I'll help you with the new block if you help me with the H/C...what a deal!

Default What is involved to upgrade to a larger rotating assembly

I noticed that one way to go is with more cubic
inches by opting for a new rotating assembly as from Lunati (382" kits etc.). Are there anywhere step-by-step installation instructions? I would be interested to doing this myself (did my own H/C etc..) but am not sure if this kind of a job would be over my head...

Thanks,

Gert

im not an expert , but , the guy who built my motor did bore the cylinders .005" to make room for the forged pistons when they heat up, ive heard that between .0035" & .005" is normal, hope that helps ,,,,,,, bdawg <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
