Great work with the heads. Most don't find that much air with them.

Hi, Did Diamond racing make those pistons? We've custom made Poly pistons at my work too. Usually for one of our Mopar customers: Richard Automotive Machine in Lynchburg VA. They specializes in Poly's too.

Yes! WHO made those pistons?!?!

And, could you tell me, er, us about the roer rockers?

Yes we had diamond make the pistons from the chamber mold we sent them. Also worked with them to lighten them by taking out extra material. If anyone wanted a set I could put you in touch with my builder to get a set based on your needs. The rockers are T&D 1.6 you have to cut down the rocker shaft stands to mount them. My heads are off to the machine shop today to get that process started.

Install for T&D

Stands cut for the T&D setup.

I love this thread...you have taken a huge step in allowing anyone to gain the same results.....if I wasn't into my 426 build I'd have a set of heads on their way to your specialist for the port work!
Thanks Scott.

What's the latest on this build?

 

[66coronet500]

Waiting for a test set of lifters from Isky. The 1.6 ratio is a tough fit on the intake side. Only a small amount of grinding on the exhaust side.

New manifold arrived.

They look like a nice piece. Looking forward to some dyno numbers.

Will you have to cut the hood to get it closed once everything is put together?

 

[66coronet500]

someone did some measurements on their 66 charger and should fit with a drop base filter. I will be using a wo23 scoop from AAR which is also the 1" taller version so I should have room.

Some grinding on the block and heads along with a special intake cup offset and the lifters fit with the 1.6 ratio.

How much was taken off the pedestals?

 

[theman440]

Are those T&D rockers made specifically for the Poly or are they adapted from another engine(s) ??

made for poly.

Thanks. Couldn't read it.
Was it difficult to get the rockers done/made.
Is it possible I can get a part number?

The part number is not in any of their catalogs so its best just to call them direct. Don't go 1.6 unless you are will to do special lifters and grinding. Takes them 2 to 6 weeks to make them up depending how busy they are.
