Thread: Am I crazy, it ok you won't offend me

I guess it comes down to the asking price for the P38A. However, if that is reasonable then I'd say go for it. What can possibly go wrong?

I was hoping you would tell me As for the asking price I have no idea whats reasonable for a car with a dead engine but he was apparently quoted 5500 for a replacement + fitting and that seems to have bluffed him.
What sort of $ are involved with doing the 4.6 heads over other stuff to fit my 4.6 short. I can do the work easily enough, its just time, but its finding parts and the electrics that worry me.
Its recently (km) had injectors done and I would want to get rid of all the LPG crap.

The car is worth $1K tops if it's otherwise in very good nick. To fit your engine, you need to change the inlet manifold and injection, front timing cover, sump, rocker covers and the camshaft, lifters and timing chain. The heads are the same as yours (maybe an accessory bolt hole or two different) so leave them on the engine. Gaskets would cost you around $100 and the labour would be yours to put in. The only curly question would be if your engine has had the crankshaft sensor mounting destroyed, it is tack welded on I believe. There may be differences between early and late 4.6 blocks too in the crank sensor mounting area.

Sound advice as usual. I might have said $1500 for the car. You can get good(?) ones for $4K if you look. Personally, I'd buy it and put an LS1 in it.

Thanks for the info bee utey that is some of what I needed to know. I have some recollection of the sensor mount but cannot remember what I had to do to fit it to the classic, if anything at all. I will go have a look as I seem to recall it being down the side of the block.
I thought my 3.9 heads would have had smaller ports and not fitted the inlet manifold

Oh and he wants way more than 1k

I agree a LS1 is an excellent idea, but it's going to cost a wee bit more than an already owned 4.6. An update P38 might indeed be worth $1500, it all depends on what's still working. There are so many unique electronic bits to fail on them I'd be going over it with a fine toothed comb before shelling out the readies. They're so completely different to your ol' low electronic Classic Rangie.

You don't actually need to do anything to the sensor mount to fit a 4.6 to a Classic, it's in the back flange of the block low down on the passenger side. It's just that the ones I've seen have had the mount removed and plugged with a chunk of alloy for neatness' sake.

Heads are pretty much identical, 3.9 heads come in two slightly different flavours depending on the year, but early ones can have certain holes drilled and tapped to match the later 3.9 and P38 fittings.
