Andy - How's the sweep pattern look w/ the Hughes rockers on the TF heads? I'm going to take a s.w.a.g. they're a little long for those heads w/o trying something like a B3RE relocation kit.

Oh, and your picture of the RAS setup makes me (once again) regret having sold mine years ago.

I wonder how the new COMP Pro Magnum (?) bushed stainless-steel rockers would work on the TFs? Too bad they only offer a 1.5 ratio.

The sweep looked okay to me in a quicky test but I need to order new pushrods before I really know for sure. The TF heads require pushrods that are about .600 longer than usual so nothing in my large drawer of pushrods was a match. I usually have something that fits but not this time.

Andy, what hold downs are you using in the picture with TF and Hughes rockers?

Those are the Hughes hold downs. (which are a copy of the original heavy duty hold downs that RAS used to make) I don't think RAS makes the hold downs anymore so Hughes started to make them. They are really nice hold downs machined from hex bar stock. They provide a nice wide area for the rocker arm to ride on.

Hey Andy,

I have the RAS also. How was the sweep pattern across the tip?

Thanks
Damon

Yeah, dying to see some running motor results with these, even OOTB results.

Just an fyi; I had rocker arms unlimited (RAS) bush a set or Isky rockers for me this year and I bought their shafts with banana groves and their hold downs as pictured above in AndyF's picture. Gary mentioned that they've discussed making their own rocker arms again for Mopars. The shafts were the biggest hold up in getting everything back as the business that chromes the shafts for them took awhile; Gary told me that they just don't send enough to the business for a fast turn around. It sounds like they wait until they have a big enough order to do them all at once; I could be wrong though.

Just info, Andy I run those Huges rockers on my 528, I rate them as the best rockers Ive ever had.

The sweep pattern looks good with the RAS rocker arms up to about .750 lift. If you're going to run more than .750 lift then I'd suggest some Jesel rocker arms.

IMM has an engine going together with TF heads and so do I. Not sure who will get on the dyno first. I'm sure there are some other guys with engines going together.

Has anyone heard a date that the intake is going to be available?

making some progress

andy f,what would be the advantage of a belt drive over gear and chain drives,i know the belt would have to be changed every year

Just a guess, easier too adjust cam adv/ret, less spinning weight and harmonics.

The belt drive provides a thrust bearing for the camshaft and it allows for easy centerline adjustments. It is also really easy to work with in terms of other accessories such as the crank trigger, dry sump, belt driven distributor etc.

Heads come out of the box ready for .700 lift so I'm going to use it.

Subscribed!! looks sweet!!
