HJ47 mods

Just got myself a HJ47 ute to do up and I need a driveline for it. It has no negine,box,transfer,shafts, radiator. Its basically a rolling chassis. Am looking into what engine/trans combo is available and a good fit. I have seen a 253 in one - it was messy and too tight at the rear, chev looked OK but close to the steering box, and am also thinking about 250crossflow. Listening for pros and cons from those who have seen or done those conversions.
Not looking for ultimate rock crawling ability, just a good reasonable power for bush driving and still getting a reasonable range out of the fueltanks.

probably the best engine and gear box to put in the old hj47 would be a 12ht motor and a 5 speed gearbox would expect around 11-13l per 100 would make it a pretty streight forward fix up

this thinghasn't even got any transmission or engine mounts, so the slate is well and truly clean. Had a 327 chev in it before , thats why I was leaning more towards petrol, and the initial purchase price of a diesel.

A good 12ht is going to cost about as much as an LS1 crate motor is IMO.

I know id be going for the LS1 (l76 etc)

I was also curious, I've heard of the "Fairy" overdrive, are there any others out there worth noting.

best motor for your truck is a 307/327/350 chev
put a 5 speed with split transfer into it.
then chuck a big arsed LPG tank into the tray

the chev looks liek it was made to live in a cruiser enginebay,.

I'll admit that the chev is a pretty good choice and fits pretty well. How do they genrally go on economy? I accept that there are a lot of variables with economy but are they usually real bad or just not too bad.

better economy than the old junk.
on lpg it will be much better than a diesel
power oh yeah
torque , excellent ( better again with a boat cam)

if you chuck a 307 or 327 you will have plenty of power without wasting un nessesary power/fuel with a 350.
