My hopped up grey motor

[Stygian]

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.

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.

Noice!

[Stygian]

Thanks guys, I'm really pumped by how it turned out
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.

Looks tough. Yeah I'd love to see a video of this beat firing up!

[Mick]

cool, i keep seeing period looking alloy rocker covered multi carbed greys and thinking that would be cool in the 2 door, but then i remember going down that track once before and it didn't suit me plus the cost of this stuff these days

get some paint on the geney pulley it's letting the team down

...the cost of this stuff these days get some paint on the geney pulley it's letting the team down

Right on both counts there Mick. I'll make that pulley number one priority this Sunday

[Rusty EK]

Looks good

[Thommo]

That looks sensational Andrew

[Stygian]

Thanks rusty, Thommo and GreyFC. Eric sure does a good job.
I think you can see your influence at work there too Jeff

Very nice Andrew , Trev .

[Stygian]

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

[Trev]

Would loved to compare the difference from my mild rebuild to your grey, would be interesting to see .
