It's nice when a good deal falls in your lap! :thumbsup:

https://www.smart8coil.com/ All this muti-coil talk reminded me of the Ishmael 8 coil stuff. I remember seeing adds for it in tge 80's.

Glad it's working for you now!

That sucks to hear, but now you know. Are there any numbers stamped on either end of that cam?

I have 60 and 10 cc syringes and a piece of plexiglass that is a little too thin.

I measured the chambers when I got them, they were 66 to 67 cc's. The diff probably has more to do with my backyard methods that actual differences.

I don't have a way to measure port volume, but they are advertised as 190 cc. I'll try to measure the throat size tomorrow (if I don't forget).

I attached the flow data for mine. I had originally planned them for a mild cammed, 408 stroker truck engine, but that plan has changed. Currently thinking about a new engine for my Duster. I have the heads and a hyd roller, thinking I would use parts I already have. I could build a 360 or a...

You cannot put the magnum rockers on the heads you linked. Magnum rockers are pedestal mount, those heads use shaft rockers. You can't use magnum intakes either, the bolt angles are different.

That's about what mine flowed. Have been thinking about putting them on a 360 with about 10.5 to 1 comp and a hyd roller cam, 234/238 .536/.540.

What specific problems did you have with the CNC Speedmaster heads? I have a set I haven't used yet. They did get a going over and flow test by a local shop. Everything looked good.

You said you were planning another engine for the future. Put this engine together as is with the pistons you have and stick in a smaller cam. Save the bigger cam for the next engine and you can build the compression and quench to match.

I haven't seen anyone mention this, but the driver side galley feeds from the number 1 main bearing. If you pull the cam thrust plate, there should be a core plug there. If the builder pushed it too deep, it will block oil flow from the main.

Bring on the van action!

Are you running a roller cam? Those bronze gears are for billet steel roller cams.
