Whats the best implant?

EcotecManiac, the ZR1 Corvette might be the car the engine your talking about came from? I think it's called the LT5, probably the best engine that's ever been in a Corvette, makes the LS1 look like a retro boat anchor that's for sure

Yep, that's the one, i was equally impressed with its power and reliability according to the owner. If you got the time and dosh, nothing beats fuel injection in my book.

Thanks for the input, I like the LT5, looks great, I can picture it in the Monaro. Are they a crete motor or available anywhere?

I was hopeing to get motor and box and loom and computer and everything from a damaged car, but I don't think any car with this engine will just pop up out of thin air.

I owned two project Monaros, HK and HG GTS I had to sell them both when I got married overseas (ran out of money ). If the Monaro wasn't a V8 originally then make sure you have whatever the original motor was also in the shed and if it's at all possible keep it the original colour (you'll be happy you did this one day). Aside from that, if you want a really fast engine for really cheap and no problems with the install there's just no option but the carbureted small block chev, it's more less impossible to build one with less than 300 horsepower and costs almost nothing for the parts. If you want more installation troubles the fuel injected version will be more responsive, but really with the cheap high performance parts available for the carby chev you'll make much more power more cheaply that way. You can just about build a Nascar engine with off the shelf parts if you wanted to. A 350 block, 9:1 compression, victor jnr or similar manifold, vortec heads, good cam. You'll be looking at a brand new 400hp easy and would probably cost you less than a stock rebuilt Holden EFI V8. And also be the right engine for the vintage of the car in my opinion. As the 350 and both Holden V8's were options on the HG Monaro you'll whiz straight through rego with either.

I was going to run a 305 chev and turbo 350 gearbox (from a 79 or 80 Camaro) in my HG and 253 and turbo 350 in the HK (still have the motor and box for the HG in the shed), looking back a 350 would have been smarter and cheaper but I was young and the 350 was a bit too much for me at the time.

Dazz I think he's talking about the original Chev small block, not the LS1, there were a couple different injection setups on it in the Camaros, Corvettes and the trucks in the 80's and early 90's

Definately 350. I'd go a Scat 383 cast crank because its not much more than a regrind. Fit mid 80's TPI injection. Cheapest and perfect for most uses. Later years had LT1 injection. Costs a lot more and gain stuff all. All up fitted it will cost less than a Gen 3 sitting on garage floor. You fit engine and Castle Auto Elecs will supply you a loom. Very easy. :yeah:

I don't think you would find those engines easily, they were a special thing made by some racey guys in Europe I think. It's the old smallblock with custom OHC heads all made just for that Corvette. If you are really interested in high tech motors, then you might consider the Lexus quad cam V8, which you can get from engine importers in Australia, somewhere

If it were me doing this conversion, I'd be looking at buying a crashed V8 Commodore. Preferably a HSV version VR to VS model. One of these should be available fairly cheaply, and you'll have the complete running gear and all wiring and control modules, etc.

Otherwise, if you really want a Chev engine, I don't think you can go past the Gen3. As above, I'd look for a crashed V8 Commodore or HSV.

Whatever you choose, your first stop should be your local registration office. They'll tell you what ancillaries will need to be fitted to make the car roadworthy. Fitting a Gen3, I'd say you'll need to upgrade the brakes a few notches.

yeah, cool, i think it was a crate motor from the states, wouldnt have a clue about the dollar figure, but i cant see why you couldnt source a loom and ECU as easy as the motor

i'd personally spend a touch more and get a big block transplant 454ci chev, cheap running donks are available and just rebuild it with mild cam, a tickle up on the heads, high comp pistons etc.... nothin beats the chassis twistin power of bb chevs.... they fit in very easy and fill the engine bay

 

[ripfast]

carbie original and powerful

 

[cohn]

y not just go a 502ci, you can get them out of the states, with 500hp out of the box?
