V8 engine identification

No it's going to go fast in both the speed and the fuel. When I was young and stupid and that engine was new (1987-88), I used to sit at 120-140KPH on the Sydney Melbourne Hume Highway corridor. Only got clicked once, at 132Km through Glenrowan. :o Have learned my lesson and sit on the limit these days.

The original conversions cost $14K, so weren't cheap and my '85 model had only 23K on the clock, it was however a Torqueflyte727 which was part of the fuel problem, a ZF 4HP22 would have saved some of the fuel cost.

The fuel was the main issue that I was looking into and I was attempting to get fuel injection onto it. In the end it was easier to go with the 4.6, however that ended up costing me $27K because I had a ZF and 120 litre tank fitted at the same time.

If the vehicle is still running with the Rockhamton engine it's probably already got the required mods. It would be worth investigating if it has top hat liners which would make it a much more reliable engine. As for the head gaskets, I would contact Bruce Davis in Sydney to see if they still have access to head gasket stocks. When he was in partnership with his brother they used to get them made in the US.

If your interested, you may be able to get someone to cut and shut a fuel injection manifold into the P76 manifold. I tried to do it with spacers, but they lifted the plenum so high it hit the bonnet. That would be the way I'd go if I were keeping the 5.0litre.

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.:D

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.

Well in that case ill re use them, cheers for that info :D
But I was going to get ARP bottom end bolts:)
Thanks for all your help mate REALY appriciate it, I think I'll have to do a complete write up on this engine one day ha.
