Thread: V8 engine identification

These are the pistons image.jpg

And this is one of the heads with a couple of rockers sat in placeimage.jpg

Also it has a Holley carb and the numbers 4400/5516 stamped on the block.
Any help with this would be greatly apriciated

Thanks
Sean.

The engine is a Leyland P76 engine, originally 4.4 litre but if its been resleeved to a bigger bore than the stock 3.5" will be whatever. The pistons look like Holden ones, a common replacement in the 80s. The number stamped on the block is for a P76 engine but stamped in an odd spot. Normally the number is stamped adjacent to the LH bellhousing protrusion on the rear of the block.

One other thing, it appeared to be wider when i had it sat on the floor in one peice before stripdown than my 3.5? But could be an optical illusion maybe?

Beeuty, thanks for the bullet fast reply lol. Are you 100% sure? Cos I got to spend a few bucks on this and need to be sure. Pls don't take that wrongly .

The bore diameter is 94.2ish m/m

Yes the P76 block is about 20mm higher, the long stroke conversion of a 3.5 went smoother with long conrods. They made the block taller so they could use stock piston pin heights, IE you can use Rover pistons for a rebuild.
Stock bore is 88.9mm (3.5") so 94mm will be a resleeve to 5 litres. My mate had one built in Adelaide. The liners should be stepped liners, IE the head gasket sits on the liner not the block. You will be using 3.9 litre head gaskets for a rebuild.

Just looked where you said beeuty, and it is stamped there too. so definitely a p76 then ???

If so are they any good? Bit late to ask now I spose lol after just spending 3 weeks porting and polishing the heads
