That is a very sexy engine. These rebuild stories make me want to take mine to pieces even though it doesn't need any work. Coloured dials are the way forward - mine are red and I really love the extra detail. Keep the pics coming, they are very much appreciated.

Nice project - do you intend to do anything about the loss of stiffness caused by lowering the upper chassis rails where the engine sits? You might want to do some extra bracing over the engine as per the T4xx race cars...

The Chassis rail has been lowered by 40mm so i don`t expect to much strength has been lost but i`m already on with adding in extra chassis to cope with a massive increase powerevil There`s no room to brace over the engine as in the Typhoon but i`ll brace the underside instead,

How did you manage to get the engine and what type of BHP will it have ..Is it far better than the LS engine .

A second brace bar will be added between the new top suspension pick up points,

I nearly went down the LS route and almost purchased an LS6, but which is the better GM or Ford? maybe thats another topic to be discussed in detailidea

Engine bay bodyshell started on sunday due to running out of steel for the chassis!!rolleyes
Most of the extra room required was found by cuting away the heater ducts that run across the bulkhead

That, and I'd say he's lowered the car's CoG somewhat as a bonus. wink

Keep up the good work & updates! thumbup

Fantastic work Andy. And that last shot from underneath is great.

Remember your friend Mr angle grinder?
Well get him to remodel that golf cart back end into something more rounded and beautiful, and while you're at it do a bit of reworking on the exhausts so they come out at an angle.
And the bonnet, don't bother putting that back on, get something a bit smaller a neater.
And cowl in the headlights

Actually, lets face it, I'm trying to tell you to bin that lump of Orange GRP and finish off the upgrade with a Griffith body. It will be perfect biggrin

Um, he's already got a Chimaera, not the low-rent stumpy square-arsed version with kitcar lights... hehe

Am I missing something?

All that new 'reinforcement' seems to do is box in the lower chassis rails much like simple closure panels? To increase torsional stiffness don't you need to create tetrahedral structures (4 sided triangular shapes?). Seems to me that strengthening just one side of a box will not really add overall rigidity, just ensure it fails on one of the other (and less visible!) sides IYSWIM.

For similar reasons if you have lowered the chassis rails around the engine I would consider raising the engine mount chassis pickups to try and 'tie' the top rails together again?

How much more power (at the flywheel) are you looking to get here? And is your name Captain Kirk, because that thing is going to go off at Warp Speed 6.........

I'm assuming you've only refitted the wheels to move the chassis around but your tyres appear to be fitted the wrong way round. It looks like they'll try to force rainwater towards the centre of the tread instead of dispersing it outwards.

I agree - the mods have increased the in-plane stiffness but hardly altered the torsional stiffness ie to handle the huge torque.

I think the chassis on our cars is a compromise of what you want and what is achieveable.

At the drive end the standard tubing is on the top and side surfaces with the bottom open and vice versa.

Could consider extending the new tubing further forward to compensate the loss of vertical stiffness.

Good luck tho.

Thanks to Tom for the heat shielding, There`s plenty left so i`m gonna use some on the tunnel
area to cut down on some of the heat soak from the exhaust
