G'day viewers I'm in the middle of purchasing enough parts to build a old school truck for a daily drive & my business. I'm going to put the cab off an TJ Bedford truck onto a HQ chassis. Now if I buy a 6 cylinder roller that's what I will have to run & thought would be ok, but my son says V8 if I'm going to all the trouble . Now V8's are cool but the 6 cylinders are more plentiful. So what's your spin on this situation peoples ? Thanks jimson

HQ chassis will get you into pre'75 but you might have to limit the suspension!!! ??? :D ;D
-
Go the six and stick a turbo Barra in it.
Just for something different.
Got a mate who's workshop was doing some work for a 1000HP Barra.
-
use a 253 v8. designed for trucks and a solid go all day engine. a blueprint and balance will make it sweet and it will sound ace without draining every fuel bowser. can use a banjo diff as well.
-
I would go a 5 litre injected crate engine, no points no carby happy days !!!
-
Depending on what state your in I'd be checking with RMS for the correct requirements for VSCCS compliance Certification before registration as you're building a modified vehicle and doing a body/chassis swap.
They'll help you with the ADR's the vehicle has to meet. The last thing you want to do is build it only to get told it can't be driven on the road.

Stick with a 5 litre, 253 pistons are getting had to find. You'll find that the 5 litre, well tuned and reasonable standard gets good economy unless you pedal hard.
Stick with the Rochester carby and don't be suckered into the holley. They actually work much better than holleys as long as the throttle shafts are not worn. With a couple of simple mods to the carby you can get them work efficiently.
Also, get the 3.08 diff and the trimatic for cheap tranmission builds.
Good luck with it. That would be one cool ride!
I use to work on all types of Bedfords as a mechanic in the late 70s. The HQ conversion would be get.......

a mate had a v12 chev engine which came from a plane moving unit chev built for the us airforce as their usual tractors couldnt shift the superfortress and others being built at the time. they stuck two v6's together. would make a cool truck engine.
-
Didn't Holden fit 253's to the J series Bedfords ? might as well stay true...
Will the cab fit ?
Love to see a CF Beddy done up :)
-
Yeah holden did fit V8s to some JT Bedfords. I already have the cab & fitting it to a HQ chassis makes it easy as a daily drive. I don't like the idea of parking a truck every time I go to town it would be a pain in the arse. I'm sure parts would be more available for a HQ then a Bedford. Jimson

slip over to the old holden website, very knowledgeable bunch on all things like what your proposing as well as a good source of bits

Thanks 80-85 Husky & thanks everyone else, for your input. Jimson
-
c w and ad smith used to be at hurstville years ago i think they moved to heathcote rd moorebank as many bedford parts as u want or steer u in the right direction....goodluck....

Here is some inspiration.
Ford onto Holden but similar in many ways. Good Luck.

I brought a hq tonner and going to install a ls1 with 6 speed box from a vx ss I brought cheap
-
Looking to do the same. Just bought a hq chassis that has been rebuilt to put an early f truck body on it. Chev small block is my preference. I don't understand using a 253. They suck fuel like a v8 but are slugs.

i agree %100. A 253 can be made to go pretty hard in a SMALL car like a Torana but for a small truck the lack of torque will rare it's ugly head. Best off with a 5ltr to start with as it is the same physical size as the boat anchor 253 with more mumbo.
-
lots of for and against the two fitty 3 but they are a neat tidy small v8 that sounds good and can run cheap. the later blue motors with 4 barrel are terrible (except for the ign). the early two barrels ran quite economically. we had a servo years ago and looked after a fleet of fords and holdens for an a/c mob. The hq 253's in the wagons and pvans would turn in 23 - 27 mpg while the 250 fords would do 18 - 22 mpg.
the real answer here is big block crate motor, why naff about? but for a budget build, 253 is as good as any and easy to find...ive got one out the back paddock!
-
Well I've just scored a HQ chassis & started pulling the Bedford cab apart to remove it from it's chassis. I have a blue 202 engine & 4 speed box in the shed. Because I'm such a poor prick, I'll build it & run the 202 but long term when I've saved some cash I'll go either 253 or 308 V8 way. Thanks for all your input. Jimson
-
give the head on the 20 some tlc and it will pull pretty good. radius off all the turns in the inlet ports so they are smooth and take out some of the boss around where the valve comes in and it will improve torque significantly. chase up a set of quality valve springs, ditch the varajet carb for a ford xe-f webber and your away.
-
253 was a way better engine than the 308. The 308 was an extension or adaption of the 253 and with the bore to stroke ratio it had it wore out way quicker than the 253. The 253 could be made to go well with a few machining tricks.
But the 308 is a better engine for just lugging around pulling a load.
If you can find one get a Leyland P76 4.2 V8.
Run rings around both.
Do not get a Rover V8. Piece of Sh#t.
-
I was keen to put one of those leylands into a clubman build but my capabilities and my dreams aligned...
-
I've been on the lookout for a Leyland V8 for my SWB Bedford van project. They are a brilliant motor with light weight and small(ish) external dimensions. I don't know where all the V8 P76's went to, but they're hard to find with a motor still in them.

Cummins 6 or left field the 2.5 turbo diesel plus 5 speed auto 4 from an lload Hyundai
-
I was thinking of going to a diesel motor.....A wrecked mid 00's Vito with all the running gear under the Beddy would be neat. But how do I get the sidepipes to sound like a V8?
