Would be interesting for Steve Heath to comment as his literature says they think it would fit.

The LS series of engines will fit into a Speed Six Tuscan...........IF.......you cut the chassis rails.
But by those rules so would any bloody engine you want.
The exhaust manifolds are the problem.
They will not clear the standard Tuscan top rails.
The T chassis cars do NOT have a symmetrical chassis.
Then there is the problem of running the air con pump.
This makes the engine that bit too long.
Further more the Mark 2 Tuscan will make the job that much harder again, by the way that the steering column is laid out, as indeed will the other T chassis cars. Not the same as the mark 1 Tuscan.
I have been hearing over and over again that this or that will work.
Well how about someone doing it and not just talking about it?
If talking got the job done then there would be dozens of them out there.
How many are there?
Oh yes, that's right NONE!
Just my SBC Chevy Tuscan and 3 others that I have built and my friend Graham who has a Small Block Ford Tuscan.
By the way......my Tuscan does NOT..... repeat NOT now run a cast iron SBC.
It runs a Mowtown all alloy SBC LS 427ci motor with LS heads.
These engines run at 650HP or 795HP normally aspirated.......like I give *uck about the LS motor"!
See .... Bill Mitchell Hard Core Race Engines.

Some people think Old is no Good S8..
Personally I like the fact that 3 wires and no sensors does the job. Isn't it also much nicer not to have any black plastic and wires etc cluttering the engine bay.
Technology marches on but for what purpose!!

You are clearly MISSING the point!
Yet again.........the Chim does NOT have a "T" chassis.
Your car has a V8 engine in place, where a V8 engine came out. That is all. That is NOTHING like putting a V8 into a Tuscan.
The question was...............has anyone put a V8 in the TUSCAN yet.............and someone asked why I no longer post with my build project?........Jeeeeez!

The Tuscan chassis is like a Cerb (only that is longer at the back.
If you have a TKO, an LS and a Tuscan to any decnet US Hotrodder they would have it all together in to time. No cutting.
Brum did not cut his chassis and the front end is basically the same - end of.
This has been done to death. If you want one, just get on and DO IT.

Remember the Phoenix Project...........it was going to have one engine for road use one for Drag Racing etc, etc. Well I've seen it. What a joke that is. It's a box of bits 4 years on and a very sad shell with stupid large wheels going rusty. Sitting in the corner of a work shop covered in junk!
That guy also told me how to do everything. But again, his car never got built.
What a surprise.

Hi Richard That guy also told me how to do everything. But again, his car never got built.

Long time no see....
A very expensive box of bits at that...according to the correspondance I saw there was £14,000 plus outstanding on the engine work
& there was a thread on here speculating that the owner was getting free board & lodging 
I can appreciate how you are getting frustrated about all the 'hot air' conversions that are being talked about after your successfull conversion
I know the last time I tried, in vain, to keep up with your 650BHP monster you thought that sort of horsepower was nearing the limits of the Tuscan chassis, now with more mileage under the belt are you of the same opinion?

This logic is not correct. Quite a few years ago a Rover V8 was fitted into a Cerb quite easily. If the Tuscan front end were the same as the Cerb front end then the LSx, which I believe to be narrower than the RV8 would fit easily but this is not the case so the Tuscan front end must be different:...

RV8 26" at headers or 30" overall http://www.v8engines.com/engine-4.htm

Some Chevrolet engine size facts.
This seems to be a topic which has a couple of people wrong footed here.
... the LS6 ... aluminium engine is,
628.4mm (24.75") this IS WIDER by 118.4mm (4.67") [than the SBC]
And this is at the top of the engine!
The Goodwrench 350ci iron engine is 22.01" tall to the TOP of the
VALVE covers, add to this the inlet and efi and you get 28.25"
The LT1/6 is with efi 28.25" tall.
The Goodwrench 350ci iron engine is, with water pump 28.75"

The LSX will NOT sit lower and further back as you say it will.
This is because the space frame on the drivers side DOES collide with the LSX when this is tried at the starter motor to bell housing area. The Speed Six space frame is NOT a mirror image centred construction.
I HAVE put this motor into the chassis to check this very point.

Surely Jellison is referring to a S6 Cerb chassis being the same as a tuscan?
Yes and I am refferring to the anomoly in that statement. An RV8 engine was easily fitted into a Cerb chassis so if the two (Cebr and Tuscan) are the same then fitting an LSx (which is narrower than the RV8) into a Tuscan would be easy. Since the latter is not easy the two chassis do not appear to be the same.RichardD said:

...Page two has statements from Steve and Plasticman stating that it should fit. But as no one has actually done it then it remains to be proven...
I know what I was doing wrong there, I was looking at page 2, as by page two you mean page one

Here are some accurate lsx measurements taken across the exhaust faces on the heads. These faces are almost vertical and are the widest point of the engine for installation purposes.
1. Across the faces, just under 21"
2. Allow 3" per side for header width takes it up to 27"
3. These measurements are taken 11" above the crankshaft centreline.
I've always said allow 28" and it'll be comfy. Measurements are on my web page somewhere.
So now you can go check the chassis top tube widths
At the rear you can fit a small clutch assembly and a small bell housing to suit if need be.

To all you tape measure heroes and Pub talk specialist.
How do I know that the LS will NOT fit unless you carve the chassis up?
Because I have had one in the bloody engine bay, that is how.
Now the Tuscan chassis rails are 22 inches apart, YES.......22 inches.
So how the *ucking hell will a 27 inch wide motor fit without cutting the rails...........over to all you EXPERTS!
Other points.
Have any of you taken any account of the bonnet "swoop" and where you will put the alternator and power steering pump?
Have you seen how much adjustment "swing" you will be left with on both of these items?
Have you any conception of the vertical chassis rail in the Tuscan chassis and how this will impede the position of the LS motor/gearbox/starter motor position and thus the forward position of the motor itself?
Have you any real idea as to how much vertical height you will be dealing with when the bonnet is down and where the maximum height will be in relation to the forward to rear position?
The answer to all of the above is NO!

Not missed the point pal.!!! I was simply agreeing with your reasoning. YOU stated that if it can be done then stop spouting and do it !!. That is what Jon decided to do when there was "pub talk" about will it wont it fit........Not interested in XYZ chassis rails blah blah blah !! If you cant see someone agreeing with you on the forum its time you packed it in !!!. Rant at the right people next time. Take a chill pill............Christ !!. You`ll be on the " Health Matters Forum next asking about cures for high blood pressure and relaxation techniques You are clearly MISSING the point!
