Street/Strip 202 Build

Posted 13 January 2020 - 07:41 PM

Howdy all, there hasn't been anywhere near enough Holden 6 goodness on here lately for us tragics so thought I'd start a thread covering my latest build.

Kept munching bearings in the old block so I cracked the shits, binned it and am starting afresh.

Had a 40thou over QL prefix red laying around so had it sonic tested - going to 60thou will be a little thin in a couple of bores front side but is usable.

Went round and saw the master Tony Knight and the build begins.

Red cranked, 9 port, 2" SU fed.

Block was pretty rusty inside so it got a molasses bath.
Cleaned up nice, drilled for external oil feeds.  Resized_20200113_103448.jpg   144.55K   17 downloads  Resized_20200113_103450.jpg   131.64K   13 downloads  Resized_20200113_103459.jpeg   178.58K   17 downloads  Resized_20200113_103506.jpg   181.89K   15 downloads  Resized_20200113_103509.jpeg   131.78K   15 downloads

Red crank is much lighter, picks up rpm quicker. Plenty strong in an NA application like this.
Blue cranks are good for boosted engines.

You’ll run a lightened flywheel, maybe blue one?

Looking forward to progress.

Cylinders have now been bored.
Grout ground for water pump impeller clearance.
Will be honed next once the grout had fully cured.  Resized_20200114_111226.jpg   91.82K   14 downloads

Yeah Tony reconditioned my head for this build a while back.
Got it flowing better. Flows enough to support 300hp which he seems to think we may crack on the dyno in the very near future.
Tis an open chamber but has had at least 100thou removed, static comp will be at 11:1  Resized_20200114_163646.jpg   152.68K   18 downloads

BA Falcon windage tray trial fitment. TK was pleased at the ease and minimal modification required to make this fit.  Resized_20200117_110137.jpg   163.6K   23 downloads
