Interesting..

Fast forward 3 months:What's the latest?

Interested to hear the outcome of the 264/272 HKS's vs the Crane 264's..

I'd like to know this as well. I am seeing 1.920" to 1.950" but I'd like to confirm.

I'm going to have to measure my setup once the head is assembled. Hopefully my head casting is decent and doesn't require too much shimming. Manley says cool bind is .950" (950 thousandths), at 1.580" install height. We shall see!

Thank you. I was aware of the binding situation. I just wasn't sure if it was possible. (Cast iron Chevy heads shim under the valve seat, but that's cast iron vs aluminum). I'm still learning.I don't believe my cams are an issue. Manley says .580" max valve lift including the rocket arm...

I know this 2 years old, but I found it searching so I'll add to it. I also have the 22125 kit (single spring).Why couldn't you shim under the seat? As in, cylinder head casting / shims / seat / spring?I'm running smaller cams (genuine HKS 272's), and curious as to a reliable rev limit...

Thank you

I don't know how to do that. I'm not very computer literate. I can't even resize pictures, lol.

Guessing no one is following so this will be my last update.

That is sort of a loaded question.. Assumong an ethanol pump is close by. Looks like it's flying on the back half of the track, which means it's easy to merge with traffic ;)

Nothing? Damn. I searched and saw TPG tuning (Andrew's 2g), journal bearing 4202, but not much else..

Good job. Love how clean it is! Wonder what it would run on pump gas / street tires?

Fixed a ghetto rigged oil return line setup, radiator had a hole in it, fresh oil change. Come out the next morning.. 5 quarts of Pennsoil Ultra synthetic all over the ground.. Oil pan has a hole in it. Yay... Got my fuel lab filter and filter to rail line/fittings as well as fuel lab AFPR kit...

I'd like to continue this discussion, except in the present time! (Fast forward ~ 7 years)..With all the changes in compressor wheel and turbos in general, now available to the general public.Is really like to see some spool numbers of any variation of the gt42 (BB or journal), with...
