Get a transit after 1976 they have disk brakes don't worry about motor just body & drop a windsor 351 v8 & top loader & put a nine inch diff out of a f100 in it . Convert to a Holden water pump they sit flatter & bingo you got a van that kicks ass . Learned they hard way on a 1974 model & had to convert to disk brakes & learned the hard way about fitting motor I cut the fire wall out to fit .But I did meet a bloke after who had done the Holden water pump trick it would of saved me so much hassle . I swear a transit body I reckon weighs less than an xy body for sure . It flew maybe because I worked the motor a bit also . If I had the money I would buy a transit that's probably 2003 model ex postal van with a high roof & try to pick up a really late model wreck of a xr8 & throw the driven line of that in .maybe even try to 4wd set up with v8 fit out back like camper . I see the picture of the Iveco it looks good but I think for a bit cheaper you could build easy. Mmmm 6ltre six speed van with Fwd option . Two sets of wheels mmm airbag suspension adjustable height mmmm built in air jacks . love heart bubble windows well maybe not the windows. Trundle tray bbq and sink Got to stop watching custom car shows
My dad had a transit. 4.1 litre, and they all had the firewall cutout and a hatch that crept into the passenger compartment in order to fit the straight six in it. You had to take it off if you wanted to change the sparkplugs.
The thing went really well, because the diff ratio was well suited to a 4 cylinder and low speed. It was fun.
Now, I think the holden V6s would fit into the Transits easier than anything else.
If it was an older transit with a straight six, I think a motor out of an AU or BA would be the way to go.
