RE: Chevrolet adds more V8s to crate engine range

[V10Ace]

The Ultimate engine for my future "Ultima"....

[anonymous-user]

I am liking the availability of auto trans with control module. For some older cars a transmission upgrade would be more desirable than an engine upgrade (V12 Jaguars, I'm looking at you and your stty three speed automatic).

A Series XJ12 with the late coil pack / no distributor 6.0 330bhp engine and a modern 6 speed automatic would be my dream daily. I wonder if this transmission has the same bolt pattern as the 4L80E

Would they fit in a 986/7? You must be able to pick up a bore scored edition for not very much, and some of these are certainly cheaper than a rebuild.

It's certainly been done - these guys will even sell you the kit:

I'll bet it bolts right in!

Yeah, bolts right in once you hack the rear of the car to an almost unrecognisable state, including the front bulkhead and cross members.. At least you'll be warm and deaf..

Bought the 490 BHP one to drop in one of my Alpine GTAs last year. Have had to use some different headers and an electric water pump to get it to work so with those bits should be comfortably past 500 BHP. It's in the car but still need to get the ECU wired in and the exhaust sorted. Should be 400 + BHP per ton once up and running

Do you have a thread I can follow this sounds like an interesting build.

Yep, I'd love to read about this too.
I loved the GTA but it was always crying out for more power. 400bhp per ton should do it...

How much does that weigh compared to the V6?

I'm 99.5% sure it is.

GM has retained the block bolt pattern all the way through from the 2-speed power glide days and the birth of the SBC in 1955.

How about a Morris Marina?

With suitably redesigned suspension of course.

There's a fair few V8 Minors out there! There's so much room under the bonnet.

Under the bonnet?
Never stopped some

Yes please. Put me down for two.
One for my Griff (sportmotive have done loads of LS conversions) and one for my land cruiser 80 as per Icon/Jonathan Ward in the US.
Connect and cruise x 2. Wonder if they do a Black Friday BOGOF?
Man maths means running two identical engines makes complete economic sense - bulk buying oils, plugs etc, easier spares stocking...
Haven’t completely nailed the figures down but I’m right on this, yes?

100%, get it done.

The LS top bell housing mounting bolt is in a different position to the pre LS engines.

A tricky fit, but I'd like a Tesla Model S with V8 running gear.

I'm guessing then there's adaptor plates available then, as I know people that have put old with new and vice versa...?

^ If you have an early gearbox then you can weld a boss at 12.00 oclock or thereabouts which allows you to bolt into all the LS engine mounts. I recently did this on a TH400. It's likely people don't do this and miss out a bolt. The Jag box may not be big enough to accept the LS flywheel and clutchpack but it may be possible to modify things.

somebody mentioned weight

total mass is low and sometimes astonishingly so when compared to other V8 and 6-cylinder engines

from a link provided earlier in this thread:

• "The flat-6 engine from the Boxster S, and an LS series all aluminum V8, weigh almost exactly the same. The Boxster S produced horse power in the mid 200's, yet a new, entry-level GM LS-3 engine, starts in the mid 400's which is higher horse power than a twin turbo! The twin-turbo factory engine weighs 200lbs. [91 kg] more than the LS and costs 3 times as much!"

the LS3 crate engine -- 430 hp / 425 lb-ft -- is published as weighing 187 kg

that's well-dressed apart from things like alternator, a/c compressor, engine fluids, etc.; the block and heads are aluminium

I seem to remember when I first laid eyes on the Flyin' Miata that word on the streets was that the engine was only 10lbs or kgs heavier than the I4 that came out.

However, that is subject to whatever I ready being correct...and also my memory being correct.

[Boosted LS1]

An LS conversion is always going to be expensive. Crate engines are very good value for the money but once you add on the correct sump, the correct front end ancilliaries to fit your car, a harness and ecu that will get you through emissions etc the price soon adds up. Not to mention the exhaust, gearbox, clutch pack , engine mounts etc. It's very good in stock trim but don't be fooled into thinking it's cheap or bullet proof. The pistons are thinner then those of a rover by a big amount.

IIRC they are also lighter than the Mazda rotary

^ What does that weigh fully dressed? Revs like a goodun though :-)
