Just a minor upgrade

Hi and thanks Tony, as much as it would be nice to have a wonderful underpowered great sounding side valve, a couple of extra horses would be really handy. I'm a bit excited cause its gettin' close to trials but I'm busier than a one legged arse kicker at the moment. If I had full dedicated time on it, I reckon I would be driving it within a week but work comes first. Also I don't mind the sound of a well tuned, tuned length exhaust, good old 351ci. But I know where you're comin' from.
Colin.


G'day Alex, I did look at offsetting the engine and trans, but its only 9deg and there's been a few friday nights that i've been on greater angles that that and still operated without breakin' my uni joints so I have great confidence it will be o.k. There's not much room in the engine bay either, but hell it's great fun achieving something like this and thanks for your comments
Colin.

Love your work Colin, if you manage to get her to Corowa next year I hope to get a good look over.
Your decision not to angle the power pack was wise, because 9 deg is bugger all, as long as the crank/output shaft are on the same linear "plane' as the diff pinion shaft. To angle the engine/gearbox toward the diff to reduce the shaft angle would only have introduced a nasty shake through the hull at speed because the tailshaft would have been "out of phase". Crank bolt & output shaft centres should be equal-distant from the hull side. You probably have already done this, but make sure the crank centre bolt & centre of your output shaft are equal-distant from the hull floor for the same reason. The carrier pinion shaft enters the hull level with the floor & hull side..

I see you have solved some of the engineering problems I was scratching my head about on my replica Vickers, such as how to re-attach track guards etc.. but I am wondering, have you, in the past, mounted the engine mounts direct on the floor before? I was considering it, but was worried about torque flexing the floor plate, and had decided to install the engine/gearbox in a cradle, attached to the floor and hull sides. Is this how a 2pdr engine mounts are normally mounted?
