O.k. I got permission from the forum member to post a few pics.

This is a GM Gen 4 mated to a 6 speed and then to the LT230. Guess what...no change needed in your drive lines as this mates up to your LT 230.

Imaging all the HP and gas mileage you could want. WOW. More to come from the forum member.

revising my earlier statement about pro flex hoses which will start to weep after 2-3 years of use due to ethanol breaking down the rubber.

Been advised to only use teflon stainless steel braided hose like this and only for short lengths where the line needs to bend. Otherwise all lines will be 3/8 hard lines.

Also been advised to pressure test all an fittings when making up your hoses. cheap insurance.

anyone interested can pm and ill give you a breakdown of the fittings we are going to use.

Umm... rad already has the shroud on it & my truck will spend 99% of it's time crawling round the bush, It'll see very little road use.

I could use the mounting bosses that are welded onto the rad to make an open support frame that'll hold the fans close to the core.

Would still like to keep the option of using a shroud open so think I'll move the engine back an inch just in case.... unless that'll foul the bulkhead ?

Nick, do you have a price list and/or BOM of everything needed? Will these fit 109's fitted with the original 2.25 or is this for Defenders only (i.e. would a Defender LT230 bolt up?). I realize that there would need to be axle upgrades as well, but this would get one step closer to being able to drive on the highway (and a easier path to A/C). A 109 NA Diesel can only move but so fast...

Been thinking about exhaust manifolds again... rather like the look of these L99/LS3 headers but as we know the engine needs to move towards the centre of the truck to make them or the standard factory ones fit.

Liked the looks of these new mounts from Daves Customs and got me thinking about making up a custom set for my truck...

So, question is.... if I leave the trans mounted on the OE mounts, would it matter too much if it all sat a bit off square to the frame with the engine on center ?
