Thread: V8 engine identification

All's not lost yet then, I intend using my lt95 4 speed. I heard they were the strongest, and if I fit a lumpy cam i read somewhere , "an auto gearbox could have problems with idling . "
Did you see my other post? " performance parts" as I say there I am thinking of fitting an edlebrock 500cfm carb & dual plane manifold can you foresee any problems there?
Can you get an edlebrock manifold for a p76?
Also previously posted I was told to use a3.9 head gasket is this right?

Thanks lotsalandies,

A composite gasket not a steel shim gasket if it hasn't got the top hat liners, both the 3.9 and 4.6 litre Rover motors have a 3.7" bore but the 202/186 Holden have 3.625" bore. The problem is having the steel shim gasket sit in exactly the right spot for the sleeve is difficult and the reason touse the composite gasket.

I would go for the R380/1:1.22 LT230 transmission out of a Disco 1 rather than the LT95 just for the 5th gear and I would put a reasonable transmission cooler on it, not just the loop used on the Disco. Forget about the LT77 on the 1980's Rangies

So just to clarify, idon't have the top hat style sleves, so I need a composit gasket. Of 94mm od.

Ideally it would be 92.075mm, but I would confirm with Bruce Davis, in any case you may have to use the 3.9 litre gasket, but use the composite not a shim.

Beeutee, lotsalandys, would either of you happen to know the part numbers for the piston rings( Holden)202/186 and the hydronic lifters( Holden) pls?
Are the lifters from a 202/186 aswell?

Also beeutee, you said rover big ends can be used,are they exactly the same?
The numbers I have on the shells are (clevite 77, 9 86 010, cb 610p)
I'm not familiar with what these numbers mean?
Any help would be great pls.

Finally ,head bolts,this engine has 10 bolt heads three longer in the centre of the inner row,are these replaceable with standard rover items? From a 3.9 ? Part numbers if you can pretty pls?



You have both been brilliant help for me and if I've stepped to far with asking all these questions, I apologise, however the parts people are being very sketchy around this engine and although there making every effort to help me in turn I need to do my best to help them.

Just dying to get things moving, lol you know how it is??

Oh one other thing, would a standard rover clutch kit fit? And if so which one?

Thanks.

Take your pistons and lifters to an engine shop to have them accurately measured to make sure you're getting the correct parts. Big end bearings say 010, so first undersize 3.5/3.9 V8. head bolts fit all pre serpentine engines, 3.5 or 3.9. Why not use the bolts that were in the engine?

Thanks for replying beeutee, yea I thought the same, I'll run the piston and lifter into auto one tomorrow and take the old rings too ,with regard to the head bolts I thought and have read you should always replace them?

Not if they aren't stretch bolts (torque-to-yield). Early model bolts are fine for re-using. If in doubt get a set of ARP head studs to suit a 10 bolt engine.
