Been working on this since May last year, when work and life doesn't get in the way

Yep 345 scout engine, it's going to have aftermarket electronic ignition, an alloy manifold and probably get a mild cam for it. Only other major inter part is a scout tailgate.

Sounds familiar ,"mild cam" one step up from original, is what my builder said would be the best.

I also plan to have aftermarket electronic ignition, with a four barrel , & headers.

Its going into a 66 I.H. pick-up we are doing. Replacing a six.

I'd be interested to know what cam he recommended Tony, I haven't got to my engine yet. The ignition I'm using is from Davis Unified ignition, it's a Chev HEI style and it's a huge bloody thing but is supposed to be able to fire a 50 thou gap. The manifold is an RPT and is significantly lighter than the original, and I'm gonna run headers and side pipes.

Had a play with the gearbox this week, to get the shifter where I wanted it I had to get a relocation kit. This meant ahh some rather serious surgery needed to be performed

And looking rather naked

Just a bit of info , No matter what cam you decide upon , Make sure it is degreed upon installation ,

You will want the intake lobe centerline at 106 degrees ATDC +- 1 deg,

If you use a fairly high lift cam be sure and check for piston/valve clearance and spring cap/valve guide. The exhaust and intake

rocker arms are 2 different ratios when doing calculations .

PS Nice work !! I am enjoying this thread

Ps Have you seen the Hamilton fuel injection setup ,Either TBI or MPFI Talk about sweet , Turn key and go ,no fiddling with

carbs , chokes etc

Cheers Kevin, I'll take note of the cam timing. As for EFI I looked into it and concluded, not at this stage as the budget won't allow it.

The RPT manifold does have bosses for injectors on it so if I went to EFI I would probably have the manifold drilled and buy blank fuel rail and drill to suit etc

Few more pics, I custom made some brackets to suit SBC engine mounts ( cheap and easy to find). And a few pics of the adapter I made to bolt up the T56. I started with a four cyl 3 speed bell housing. I lathed up a donut out of plastic that went over an old hyd centre bearing and inside the hole on the bell housing, then made a MDF template for the bolt holes. Then I transferred it all to a lump of 10mm plate and cut/ drilled it out. When I mated it all up I found that the clutch plate didn't fully engage the splines on the input shaft by 8mm, so I stuck the bell housing on the mill and took that off the back. I then decided that the being a cast bell housing I would put some reinforcement under it to take the bulk of the strain. Now I know that the whole thing is concentric I can tidy it up.

Bump! 

I've  been chipping away at the rod most of the year, the steering was tricky to get right ( lots of hours sitting on a tractor helped) but I sorted it eventually.

 

Oh and I found a use for a Briggs & Stratton Conrod....... Best use I've had for a bang & stop in years..........

Got a bit more done over the past weeks, radiator and grill are in, headers tacked together, the aircleaner is a gutted oil bath off a f700 ( I think).
