Hiya Dave, The rods do stretch, my old school blown 11,000 rpm BBC had ~.090" piston to head and you could barely see the very minimal contact. A lot better Alum rods out there now(this was in '94) They do shrink from work hardening. I can't advise on clearances for that stroker as I've not do...

aluminum rod trivia I have a customer that was concerned about rod stretch. I keep notes and made sure the room temp and parts are the same as my initial measurements. For 3 years we measured at season end. Each year the rods decreased in length 1-2 tenths per year. I cannot say for certain the rods...

I would like some bearing cats from the 70s.
I have PDFs of the modern stuff but they are a pain and don't contain near the info the old versions did.

What diameter is the rod journal on that crank ?

nominal is 2.200

8K with that stroke!

Did I mention a block? Ahh, no because it's not the subject here. FYI the block is correct for this app.

I added Dan Olson wet sump and vacuum pump to the original specs.

I got roped into building this using a myriad of parts. It is the biggest CI I have messed with and I am having some doubts about clearances. The patient: 706 bbc, 14.6, BME alum. rods, Pontiac heads, 300 shot of n2o, Dan Olson wet sump, vacuum pump, 2400 lb car, bruno trans. The rod bearing clearan...

DC stands for Dan Cap or Danekas (RIP) for short. I forget what the Cap stood for. Marc Danekas made a "Super blower" with really large diameter rotors for TF but it never caught on. I suspect the fuel systems of the era couldn't keep up. Lucille Lee (RIP) drove Marc's TR3 resin TF in the ...

Agreed. Rocker balls and rod nuts for the budget win.
