Outer Limits 4x4 Board

My 1fz-fe motor needs the valves reseated but instead of getting that done i've been thinking of doing a v8 conversion. I have several options i've got a red 308 i could use or i could buy a 350 or i could use the 454 i have sitting in the shed. I would run an auto behind it the one i have is a stage 2 shift kitted turbo 400. I would also run straight gas.

Should i do it ????

I would also either buy a bike or fix up another car as a cheap daily driver
as i live about 15 k's from work. The cruiser would then be used for weekend play and a bit of towing, horse float and car trailer.

Go the Big block

Go the big block!

Post up your 1/4 mile time when its done.

Prepare to break stuff

go the cubes

big block

Go the Big Block i fitted 502HO crate motor about 10 years ago into a 75 tray and it went real hard it also had a T400 auto. Ive got a 454 with Bowtie alloy heads and all the good stuff that goes with it in my 80UTE and a mate of mine has a 7.4 Vortec ( 454 BB ) in his 75 ute with the 75 5 speed and it uses a gearbox every 3 years ( 70 k ) they just get real noisey but havn't gone bang and he drives real hard all the time. The biggest part of the job is getting the exhaust in but it can be done as ive done it twice in 75's.

why not put in an old 2F motor, you could probably get one cheap as chips....

HAHAHA nah just kidding, big block all the way!

so all your car requires is the valves reseated, which is only a grand or so, verses masses of coin for a complete conversion?

Am I missing something?

YES.... 1fz-fe vs 454 BB....

If ya pockets are deep enough for big block fuel bill weeell no contest really now is it

Apart from taste, brain cells and looks and the latest news article posted while you were typing ... You are also missing the excuse this bloke needs to justify to the minister for war and finance to step up to the richer fuller flavour that only a big block can provide..

IMO you just cant beat the noise power and feel of a BBC that is the reason im thinking of putting it in my cruiser. When i was 21 i had it in a HQ ute and man was it fun on the road so i can only imagine how much fun i can have in the bush. like i said it would mainly be used on weekends so fuel bills wont affect me too much. I live in the foothills of the strezleckis, about 30 seconds drive away from home are some very good tracks on which to play so i dont have to travel far to have fun.

Any ideas on conversion costs bearing in mind i already have motor, auto, radiator and exhaust i can modify to suit and i can do most work myself except wiring.

1k for adaptor to transfer and maybe lengthen/shorten some tailshafts depending on kit, 500 for shit like hoses fittings and niggly crap and depending on where in the valley you are I may be able to help you sort the wiring end of it oh and anywhere upto a grand for exhaust oh oh and 350 for a ratchet shifter for ease of conversion

do i need to provide an answer to that one

oh and yeh, go the big block

ok this may sound a lil softer but u might save some money buy fixing your 1fz-fe and fitting a supercharger or turbo u will get equal performance if not more from ur 454 v8 in standard form and probly use less fuel and it would be lighter over the front so ur truck could still turn at speed.

a 454 can produce anywhere between 350hp and 500hp in completely stock chevy specs. Lets assume its one of the more common motors producing around 420hp. Any mods will easily see this 450+, and its very hard to find a 454 these days that hasnt had at least some work done to it.

1fz-fe has about 220hp? so that is gonna be a big ass turbo or supercharger to double the output of the engine. I think custom manifolds and fuel system would be in order, aswell as a full rebuild in the not too distant future since the bottom end wont take more than about 6psi for too long. (need about 15-20psi to generate 420hp)

A 454 would be a pain to get emissions approved wouldnt it?

ok i was thining standard 454 was only putting out around 250kw standard then a turbo 1fz would make that but if u want more go for it but be prepared to destroy drivlines it would have so much torque, u may want to invest in in a road ranger gearbox to handle it.

but hey if u just want a v8 75 i'll swap ya mine cos i'm looking for a 1fz 75

his stage 2 shift kitted turbo 400 would be up to the task.

diffs cv's and hubs are another story though.

do you have any suggestions as to what cv's diffs and hubs to use?

i have got a 9 inch diff i could use

Wouldn't bother landcruiser centre is just as strong unless you use a billet carrier in the 9", you might asweel put a detroit in your cruiser centre, just use standard gear and see how long it lasts, you will want a detroit rear but or you'll be lighting the inside tyre everywhere

I agree with cloughy, the cruiser diffs are probably as strong as a ford 9" unless you build the 9" for strength which would cost a bit id rekon.

Is your front diff a 9.5" or the smaller 8" (8.25?) I think the smaller diff started about 91?

If its the smaller diff it certainly isnt up to the task. I'd definantly think about swapping a pair of 60 series diffs under it as they will be stronger (front anyway, the rear would be virtually the same strength, and swapping the pair means the pinions will be lined up right for a 60 series transfer case) even GQ diffs would be a good ugprade from the 8.25" diff.

The cv's are probably not going to last long. Longfields would be the go.

Factory (Aisin) hubs are strong enough as long as you make sure the hub nuts are tight. If they are even a little bit loose the hub can blow to pieces with a v8 driving it. You can get a special gear for the hub which is designed to shatter before the hub body detonates. These mean that you dont lose the entire hub or the cv (splines can be stuffed when hub goes). I think longfield make this aswell?

If your after stronger diffs than this i guess your looking at DANA 60's or something. ANd they are expensive.

hehehe dosn't is suck how u gota upgrade ur whole drivline when u fit a v8 i blew my rear hubs apart the 1st night i had my ute and it's only a 308.

drive it smooth on oroad and don't dump clutch ur standard driveline should hold up for a while.

I think running on straight LPG gets around that doesn't it?

i would of thought running it on lpg would be the only way anyone could to afford to run a 454

Thanks for all the info guys. I have to concrete my shed floor which will be hopefully in the next few weeks and then decide what i will do. The big block is in front so far.
I will let you all know what i decide.
cheers.
