Thread: 3.5 - Increases in Bore and Stroke

No, sorry Garry.

Davis used a stiffening plate on the sump face of the block. I know the heads used Chev valves.

Bruce Davis would know (Davis Performance Landys). Bruce is John's brother and was his partner in JED Motorworks before they split. Bruce is at the same location at Amaroo.

I have the JEDM brochure with some info somewhere in the garage. I'll have a look for it later today.

Thanks Ron.

Attached is the pamphlet I received with the car when I bought it. The marked items indicate what the previous owner had done. Note the prices are 1989 prices!

So I may have been wrong - mine may have been 4.8 litres - it had the bigger valves and aftermarket EFI system (Haltech). It certainly did go like a scalded cat.

Thanks for that Ron - great stuff - they are huge prices for the times.

Cheers

Garry

I am in the process of rebuilding the original 3.5 out of my RRC. I am not in any hurry as I have a 3.9 in it at the moment.

I have a stroker crank for it (second hand) which came with pistons, however the pistons were sized to suit a 3.9 bore, not a 3.5 bore. I don't want to bore the 3.5 out to the 3.9 bore size (200 thou oversize) as I don't want liner movement issues.
To overcome this we have sourced some Holden pistons which are the correct diamter for a 3.5. They will need the pin holes slightly reamed and the tops decked a little too.

Once that is done the rotating assembly will be balanced and I will put it together. At this stage I haven't organised a cam or what will be done to the heads. Once those are sorted I will get a chip written to suit.

Is the crank a 4.2 stroker crank?

I have a 4.6 crank you can have but it had a bearing run on it so it needs a grind. It was running Ok when I pulled the engine out of my P38A. You can't have the engine as I have a replacement crank to fit into it (don't ask me what I'll do with it as I have no idea). It was going to be put into my V8 County which I have since sold.
