wondered if any of you guys would have a use for it

[brammo]

Why?

[james]

The engine might make an "interesting" project for somebody (if it would fit), but the gearbox would only be useful as a coffee table or novelty doorstop.

The gearbox is a fairly standard T56 6-speed box - not much good for an Ultima, even though it can be configured as a transaxle by replacing the tail section with a diff. The cobra people tend to be very keen on these though - there are bellhousings for the SBC available. I bought one of these a little while ago and swapped it with the standard gearbox in my HSV - the ratios are much better for spirited driving than the standard box.

I've been keeping half an eye on this auction too...but I'm going to stick with my original plan to use an LS6 motor.

I have got my eye on a 1999 LS1. I was orignally shooting for an LS6 but the price on this is pretty good. How upgradeable is the LS1?

[Miraz]

Most of the parts are common between the LS1 and LS6 - main differences are the head design and stock camshaft.

Have a wander round www.ls1.com for more information on tuning.

I'm wondering if it would sacriledge to put the aston engine in an ultima, or whether it might actually be a match made in heaven. Lots of revs, very light, seems like a good match. What do you guys think?

[ultimasimon]

I thought about this innitially - British Car with British pedigree engine but then I realised...

Only 420 horses

[MattYorke]

True, but 420 is as much as I'm shopping for, although at the bottom of my range.
I'm not sure it would fit, I think it's far too long. I wouldn't mind modifying the firewall, but don't really want to have to stretch the whole chassis.

[JCof T.O.]

Are you certain that is lighter? It looks like it would be heavier.

[james]

It's only 420 horses in standard trim, but it's a very tunable engine. My neighbour has had 2, and he told me that he was looking into getting his upgraded to 500BHP. In the Vanquish it kicks out 460BHP as standard, so that doesn't sound unreasonable.

[Steve_D]

There's very little option to moding or moving the firewall/bulkhead as you sit against it on the other side.
Could be possible if you're a shortarse.

Please could one of you guys with a chevy/G50 measure the distance between the back of the engine block/front of the adaptor plate and the centreline of the driveshafts?
Thanks

[boosted ls1]

There are quite a lot of differences between the ls1 and ls6. All the vette units have fly by wire throttles and big wing sumps. Ls1's have a cable throttle body. Later ls6 has a sand cast block with windows at the base of the liners. Ls1 block is die cast. The vette and Ls6 have a better intake manifold and vette motors have higher compression and more balancing done on them. Later ls6 has D port exhausts, teflon coated pistons and sodium valves in them, inlet & exhaust and a split level sump. The ls6 is very expensive, the ls1 is cheaper. There are at least 4 factory stock exhaust options and 4 sumps. It's a case of knowing exactly what you want and if it will fit otherwise you will have a load of parts left over which need changing. This is why I bought a load of stock,to be versatile. You should either buy a stock ls1 and tweak it and the ecu or build one up with after market management. Also, if you go for a vette unit the gearbox is a transaxle item so you will have to source a t56 from elsewhere or think about adapting something else like a US T5.

[MattYorke]

Well with an overall engine length of 970mm, I don't think there's any way the Aston could be made to fit. :-( That's almost as long as a rolls royce merlin I reckon.
