probably a stupid question. but ive pulled the six out of my vl and have a 308 for it, i thought it would go straight in but some people are saying that vls have a different k frame for the six and the 8 so i need a vb-vk one. is this right? what else must be done? cheers

do a search, there is probably info on the conversion. If its a VL, chances are someone on here has done it already. Will save you a lot of time.

Why not use the VL V8 K-frame? They did come in V8's....

A Vl-Vs one will bolt straight in but can cost up to 500 dollars from a wrecker, and i do stress up to...u should be able to find one much cheaper. they come up on ebay from time to time. You will also need the crossmember for the gearbox you plan to run...this will have to be a vl one as the chassis rails in the vl are different from vb-k. Tailshaft will need to be changed. since you will already have the 6 cylinder fuel pumps there you will be able to use those...providing its a fairly stock carby fed 308 so if theres a mechanical fuel pump on the engine it will have to be removed and the opening blocked off. Other than that its pretty much straight foward wiring etc. Vl v8's have the battery tray on the opposite side to the 6cyl. also the power steering is on this side (should your car have it) and you will need to change over the power steering lines to the v8 ones.

if ur going to do this conversion, dont leave it as a dirty carb.

i got a supra 5 speed conversion for it. its out of a vh 308. so the gearbox crossmember will still have to be changed??. there seems to be alot of people who are changing there injected 304s to the big single plane with a carby on top though. and my battery is already in the boot so wont be a problem.

Yeah, the Gearbox crossmember will have to be changed...castlemaine rod shop should sell one off the shelf for this conversion. the one for my turbo 700 was $130 with the postage included to QLD. Although im changing to the injected engine its only because i bought it cheap and had to do a rebuild anyway. Personally i think Holden V8's with carbys a great...basically all there is to really **ck up on a fresh engine is the carby itself or the only thing that ever really goes in the HEI distributor is the ignition module. You dont have all these different sensors and crap and need to get it re-dyno tuned everytime you change something to get the maximum performance out of it. Carby engines are as great and reliable as everything else when they're set up properly. Should you choose to go the injected top end you will have the expensive cost ive just gone through of wiring loom etc.

Im at the same point JoshV8inj, Do i rip off all my injection stuff off my 5 litre and go a high rise manifold and carb, or stick with injection!? Can't work out which would be better off really... injection = newer, fuel efficiency, easy starting etc...

injected all the way

mate is a prick off a conversion but not that hard mine was a six and i changed to a V8 l brought a k-frame but i got manual stear which different to power steer k-frame i letf in the 6cyl k-frame cut off the engine mount points and made new ones .the wiring is the most pain you will have to change dash cluster or get a new speedo cable made wireing up the oil temp volts fuel creates a lot of headaches . id drop it all in bolt it up leave the injection and send to a auto sparkie and get them to wire up the injection and have a cheap cruzer that will still go hard

Can't work out which would be better off really... injection = newer, fuel efficiency, easy starting etc... Yeah, i found it a tuff choice...as i say, I love carby's but i did buy this engine cheap and more than anything I've mostly only stayed with the injected top end because i wanted to learn about it and playing with one is the best way i could...not to mention, although it is a bit more of a popular conversion these days, it is something different. Every sensor and stuff that ive stuck on this engine is new though, its all new so as i shouldnt have any problems with it. Realisticaly though, the money it would cost to put a high rise manifold and carby on vn heads is gonna cost around the same as having all your wiring etc done for the conversion. those manifolds cost a bomb. Ill probably stick with this car for a while then go back to something with a carby on it... Id really like to build a dodge charger. should be able to find a project to start with for around 20 grand.

Theres a VS EFI setup heads upwards that will bolt onto your chariot for $800 on this site.

Thats why i did say that a carby set up would cost the same as an injected conversion by the end of it...but as we're on this topic, I cant justify most people putting a $700 throttle body on in place of a carby that will cost like 2-300 bucks. While the harrop manifold, 4 barrel throttle body is a proven method of power...providing you use a big enough cam to suit...not everyone can afford to spend an extra 1600 dollars on manifolds and throttle bodys and another 500-1000 on wiring when they may have a perfectly good, carby-fed engine sitting there....therefore in that sense...800 dollars for a manifold is a bomb.

I looked into this on my VL V8 come rebuild time and basically price and ease of tuning was the major factors in going to a carby , $450 for a 650dp holley new and $350 ish for the edelbrock manifold and it was all sorted . Car cranks out 210rwkw but is mainly driven at the track ( circuit sprints ) as a streeter its not so nice. adam

if you are going to drive the car i would go EFI i havea vk with a vn 5 litre in it. turn key. drive away. you talk about always needing things retuned on an efi when u change parts ? its the same on a carby. they dont tune themselves. you can pick up a vn 5 litre smashed so you get everything you need for the conversion relatively cheap.

To tune a carby is to turn 2 screws on a holley or 3 on a rochester and a bit of knowledge. to tune an injected engine is 3-500 dollars on the dyno. If you can get an injected top end cheap enough and have the engine set up how you basically plan on keeping it, and can afford to do all the wiring etc, then go for it! tune it once and it will stay good, start easy in the cold and providing its got all reasonably new sensors on it you shouldnt have any problems for a long time, and wont cost you particually any more money apart from general maintenance... and you will have the bit of left over cash in your pocket from the fuel you'll save. even a stock injected engine will push your vl along quite well, a lot better than the 6 (no disrespect meant to the rb30- great engine)
