Well been crazy busy with family visits and such but finally got back into today by dropping the body on to see where the motor was going to sit. Unfortunately it was sitting too high because the intake was pushing the bonnet up by an inch or so out with plasma cutter and mig and managed to drop it by the required amount and still left about 4mm clearance on the harmonic balance thus far. And now that's where the real fun began starting with the gearbox, I mounted the box outside the car and then proceeded to drop it in as one unit (But) the box is so damn long I couldn't get it up on the rear crossmember and clear the tunnel/firewall and to top it off the OHC's were hitting on the front body support rail.
So messed about for several hours trying alternative solutions but came up short or should I dare say long Lol. So separated the gearbox and shoved that up into position strapped it up dropped the motor back on the floor shut the shed door went and sat down and just cracked a can because tomorrow is another day.

Hi Psycho,
just to throw it out there, I have a LS3 and a TR6060 and I was no where near having to notch the front cross member. Are you sure you do not have the motor too far forwards? And I was able to install these already bolted together. I put the gearbox support in after the gearbox was in position.

Could you have got away with a smaller under drive harmonic balancer? The one I put on my LS1 is about 1.5" smaller than the original.
Cheers

I'm pretty sure the FF5 kits weren't really engineered to handle the 5.4 engine due to the extra width.
I'll be interested to see how you install the steering bits, headers, and the footbox so you still have room to use the pedals.
Lots of pics would be helpful for many guys wanting to use the 5.4 powerplant but haven't gotten over these hurdles yet....

Jethrow no the motor isn't too far forward it's just the size difference between ford and Chev donks and the TR6060 is out of a FG so the rear extension is ridiculously long, when I refer to the gearbox and the rear crossmember in my previous post it's not the mount its the structural cross beam I haven't even mounted the the gearbox mounts.
Mike I did consider that option but as the crossmember is so large I thought it would be easier to notch it than try and remove the the pulley in the end I think AlbanyCobra sums it up the best you need 10mm clearance all round the motor.
Thanks for the feedback fellas I really appreciate your thoughts and opinions
Regards Psycho

Bob you are right with the size of the 5.4l yes I have had to slightly modify the foot box and even the pedal box I have spaced the motor back over to the left hand side as the US push it couple of inches to the right hand side, the steering is not so much of an issue with out the headers fitted but may have to change once i start to fabricate them I have a few pics in my albums and a lot more still on my phone, once I get more time I will upload those mods

Why not change the rear housing on the box to T56 and move the engine back. This would make your weight exchange a lot better and reduce understeer from having the weight transferred backwards a bit. This would also assist with gear shifter position.

You could probably swap to the main shaft and extension housing from a GM T56 for a shorter box. Most of the parts are interchangeable in the T56 box.

There is another bell housing with the starter tucked up under the block where they used to be -- if thats any help.
The one you have is the "Aston Martin" version go for the "American " version -- apparently

Chinese Safety boots. I spent a lot of time working in China back in the 90's. So many building sites I saw where guys just wear shorts and flip flops and they are welding or wiring up reo, pouring concrete etc. Ouch!

Thanks Ian,
The kit is very comprehensive and would be very easy to complete if you stay with in FFR's parameters BUT as we all know everybody is different and customising to ones own taste is what keeps us all individuals and very busy lol. Wow that sounded a little deep heheheh
Thanks mate
