Yeah it turned out pretty good after a few teething problems, we made two and one is fitted on the real engine ready for the engine dyno and the trying of a couple of different cam changes ( without removing the sump)
Fairly unsuccessful couple of days on the dyno as we didn’t have the right parts to get the Weber’s right try again in a couple of weeks... we couldn’t rev it over 6000 without it running out of fuel and surging but pretty promising signs when it made 212hp at 5000 then 262hp at 5800
It looks very impressive indeed, but I'm more curious about the parts I can't see, that is, what's behind the perforated panels . . .
How do you make an engine dyno?
It’s a blue block and Crank Clay crank is de burred shot peened crack rested then balanced. The rods are H beam rods running Clevite small journal chev bearings made by R&R racing in the states I can’t remember the length but they are about as long as possible and the pistons are forged CP Carrillo out of a 3.3l v6 Chrysler and a stud girdle on the mains. Modified std oil pump external pick up on custom sump ooh and the block was machined for a small block chev rear seal
Thanks that sounds like what’s needed for big revs. The blue rods are pretty good anyway I’m told. You didn’t mention anything special about the rod bolts. But I’m sure they will have been given some attention. Quite a job to get those revs with the longer stroke I’d think. Will be interesting to see what you can wring out of it. I hope nothing breaks.

These Holden in line sixes love to pull the bearing caps and bores out with them at high revs. The longer rods relieve some of the throw that stock rods create when revved hard.
The stud girdle also helps keep the bottom end in place. Sounds like this engine will go good. What is the actual cubic size ??
Always fun getting them to their peak.
