chevy V8 conversions

[crushers]

it seems in countries were the diesel is very common and the chev engien is rarer it is the other way round. [from crusher]
True here, good point, The holden V8 is a popular swap, very tough and no problems [carby,float]& 400nm of torque. The gm turbo V8 diesels are considered very cool indeed. It seems to amaze most from Oz that you guys do not use them. I am aware of a 75 series around here that has a 454 chev in it,believe it is a lot quicker than the 351 hj75 I posted a while back.Horses for courses.

My biggest problem with a V8 swap is my chevophobia. as soon as a Toyota with a chev engine comes anywhere near me i start to shiver uncontrolably and spontanious uttering of the foulest kind escape my lips....

That is a paradox, but you guys seem to have better diesel mechanics down under

I'll make some comment on the tyres, I currently running 285/75-16 Motorway mongrels which are a copy of the Simex extreme trekers, my under standing is that these aren't available in the states but i have tried to attach a picture for your reference. These are VERY agressive tyres and will generally climb and dig at any thing i throw at them, but even in sticky clay and mud they still do block up.

As for resale value, by the time i'm ready to replace this vehicle it wont be worth any thing.

I figure a vehicle used for competition would be well used by the time resale comes to mind

The closest we have to your Jungle Trekkers is the Swamper LTB. They are narrow bias ply tires and are very loud on the bitumen. Are Jungle Trekkers radials?

I thought all egine swap depends the kind of off road that you loves to do. In my case I love my diesel, is the better option in my mind .. Anycase also I thought a good clean sharp swap for a Chevy is a option .. if you like go with yout TLC onto a sandbox and play ..

About the tires, in Italy simex and boggers are options to buy, recently they make a test same jeeps same climb ( mud climb ) and better performace with boggers than simex extreme trecker.

Dood, no offense, but 'VERY aggresive', they ain't. I must confess that I've never had the opportunity to wheel on or around those tires, but they look like any other all terrain tire on the market in this part of the world.

If I get my act together, I'll post excerpts from a DVD I just got that very plainly depicts my point.

In the video, a high HP buggy, on 44" Swamper Bogger all terrains, with a sprayed 460 making a claim of 700 HP, spinning the tires with every ounce of power, is barely able to churn it's way through a mud hole, but to it's credit, it does make it. 3 vehicles later, another buggy powered with a Cat 3160 engine with some actual mud tires, putt-putts through the same hole, no wheel spin, no high revving, only using a fraction of the available torque of the engine. If you want to play in the mud, get some serious tires. They even make some in your size. And they're cheap. You can get them for way less cost and effort than your engine transplant. Leave the wheel spin to the chumps, and leave the chumps stuck in the mud.

agreed, tire tread design makes all the difference in the world....

 

[Tapage]

In the real mud world .. huge boogers over spinning get you stuck as same as AT tires .. so good tires with apropiates rpm are a big diference ..

Yes agriculteral tractor grips will certianly do well in deep mud and slush and alot of other conditions, unfortunately the vehicle needs to be Road legal in NZ, and tyres like this aren't. Chains work well to, but these aren't good for speed and are excluded due to rules (which also exclude tractor grips)

Also the intention isn't for a mud plugger, the type of terrian it is to be used in ranges from swamp, to deep water, to rock, steep greasy slopes and courses are generaly designed not to be driven, hence the term winch challenge. However the further you can go the better.

Sounds like fun! I am impressed that you want to make a competition truck that is still road legal. They do, as a matter of fact, make a handful of agri-tires that are speed and DOT approved (Like the Michelin XM27's), but $$$$$$$$!!

Often times, when the rules disallow something, it's not because it's bad or dangerous... just becase it's an unfair advantage. It seems strange to me that a competition would disallow creative solutions that are effective because they are an 'unfair advantage'... so they make a rule. In your competition, at least, by keeping the trucks to street slicks, they get to sell more winches, I suppose. But at the same time, they are perpetuating this myth that trucks need to have high HP and tire spin, when it's not at all the truth. I suppose that when I host my own competition, I'll make my own rules to serve my own self interests...

Keep us up to date on your progress in this competition. It's always fun to cheer on a Cruiser... especially a diesel one. Of course, I have also been known to offer a the occassional cheer when I see a chev powered truck lose.... especially to a diesel.

I can understand not wanting to smell diesel if you work with it all day, when you are driving in a cruiser you never smell diesel maybe if you are behind it working on something whiles its running or something. Not only do diesels have more drivable touque, they are more reliable, have better fuel econmy, you have the option of running different fuels. Of cousre the pimp factor is also nice, of someone saything is that a diesel, woha thats cool.

We would be alot further off having alot more diesel cars and trucks in north america expecillay if they all ran on WVO and hemp oil etc. The oil business is a messed up thing, The combustion engine has been obsolete for 10 or 15 years.

I guess in the end it is purly preferance, I like diesels!

Hi

my 13bt in my BJ71 is slowly dieing (260000km) and is also not really up to the sort of driving i am aiming at doing now, particularly as it does not rev high enough to effectily clear the tyres.

I have access to a 350 - 4speed bell housing.

My main question at this stage is does the 4 speed bell housing bolt on to the h55f 5 speed or is a different bell housing needed??

thanks in advance

I'd understood the 'B' series gearboxes had a different input shaft (too long?) that might cause issues...

 

[Tapage]

Yeap .. you need to do some " mods " to use for a example a 3B engine with H55F tranny ..

This guy asked a tech question about a small block swap and 90% of the responses were chat about why he shouldn't. This is the kinda of stuff that makes it harder to do a tech search (I'm guilty of it myself). If you don't have anything constructive to add, don't clutter it up for the rest of us.

I would kill for a diesel in my cruiser, but that's my opinion. I'm not lookin for a neck snapper. If he needs more rpms or hp, you all know a oil burner isn't the answer. Let him do what he wants.
