I got my engine shop to fit bronze bushes into my chevy rods to take the Rover wrist pins. they drilled an oil hole in the top of the rod and through the bushes as well.DaviesDJ wrote:Ok guys, now winging its way to me are a set of NASCAR Carrillo used 6 inch rods for my new build!going to grind my 4.6 crank down and offset to 89mm at the 1.85 inch diameter as required! Have been discussing options with mike(kiwicar) who has been great with advice. BUT was wandering what piston options to go for??? Wrist pin is 0.86, and I can have a comp height of much above 1.2-1.22 inch. Think the ford modular 3.7 inch big bore flat top/shallow dish is my best bet but was wondering if anything else is about??? Perhaps a bit bigger then 94mm??? Cos use a Chevy but don't like be idea of drilling out the small end/ wrist pin hole to .927 or whatever - seems a big jump taking away a lot of metal. Any thoughts??? Ohhh by the way, rods and bearings 144 dollars.
This way if I decide to change for a chevy piston I just have to get the bushes popped out

I'm sure my comp height on the Omega's is small like the 1.22" you mentioned.
