I started off with this engine…

And yesterday I picked it up…

When Eric gave me the documentation on what he done to it, I asked “So it’s pretty much a de-tuned historic racing grey motor”?

“Tis” was his reply.

Never ask Eric for a mild engine rebuild. :mrgreen:

Specifications

• Fully ported head from the 1955 Crowfoot Holden Special

• K-Line valve guides
• Holden Ecotec V6 valve stem seals
• Resurfaced lifters
• German made Mahle pistons
• 9.8:1 compression
• Polished, crack tested and reground stock crank
• Polished, crack tested, closed and honed stock conrods
• Lightened flywheel

I’m stoked with the result. Can’t wait to fire it up.

Many thanks to my engine builder Eric Worner; David Reid for supplying the ex-Crowfoot Holden bare head, cam and harmonic balancer, plus all other little bits, pieces and advice that Eric needed; Bernie from Martin’s Engine Reconditioning for some machining work; Nigel from Xtreme Fuel Systems for the carbs, fittings, linkages and braided hose; Alan Fountain for the frogmouths and the forum's own Dave Mac for vapour blasting the rocker cover and intake manifold.

Thanks guys, I'm really pumped by how it turned out :D :D :D
Nathan, I will take a vid when Eric comes over to run it in. That'll be in a few months after we paint the car, which we are hoping to have done before winter.

Cheers Trev :D. If I hadn't already given my grey to Eric to do, I would have pounced on yours.
