Thread: Holden V8 into a RRC

I would use the turbo block as you are more likely to find an adapter for it, since the 4.6 came out not many bother with a holden/ chev V8 unless its EFI. Dont know how long the R380 will last but T400/ T700 or beefed up ZF would be my choice.

Thanks Loanrangie , yeah I have a couple of T700's ,thats the 4L60 , not the 4L60E, I just dont think there is an adaption from the T700 to a 230 tcase available , only seen adaptors to the T400 , which I dont like (unless you need a transbrake LOL).as far as Im concerned the Holden/Chev engines will have Twice the power for less than half the price and be more reliable and cheaper to operate than any Rover V8 .

Theres definetly some t700 to LT230 adapters out there, i looked at a few for my conversion when i was considering using a an auto, i actualy ended up with a patrol 5 speed box with a bellhousing from dellow to suit the LS1 and a LT230 adapted to it....

For the t700 to lt230, i think its overkill engineering or something like that in sydney that does them, if you look on outerlimits4x4 there will be more info on there about it i think.

Cal415 , rung around all the conversion mobs , and they all said bad luck , nobody does a Transfercase adapter to a T700 , 4L60 , only adapters for a T400 (yucky 3 speed ) and a 4L80E , which is nothing like the 4L60 (much longer , different splines)

Hi 400,

Another option is the Ritters conversion C4 or C9 auto in front of a truncated LT 95. I have a bulletproofed C9 version behind a Chev. Would buy a similar RRC tomorrow. Uses stock trans mount posi and driveshafts

Shotlister had one for sale on here recently, don't know if it was a C4 or C9. Very nicely made bellhousing, adaptor housing, etc. And all very strong and simple.

cheers, DL

What would the clutch arrangement be ? Ive got both Holden and chev pattern blocks and even Ford y-block crank in Holden blocks .Any help appreciated

why bother, all you will gain is a close relationship with your driveline supplier.

Have mate building an adaptor to suit T700 4 bolt on ext. housing, not 4L60E which is 5 bolt, to LT230 after a huge ****fight with Overkill, that seen him reclaim his money, he is close to completion, but not planning on parting with any until its tried and tested
