Hi,
Im helping my father with hes Range Rover/LS1 swap that he just started.
He got a custom bellhousing made for the Rover gearbox and a LS1 engine but its straight from the foundry with noting machined at all. So what i need is a technical drawing with the bolt pattern for the bellhousing.
Can anyone help me?
Thanks
Thomas

I don't have or know where you can find any, but any SBC or BBC bell housing bolt pattern will work for getting the dimensions.

You can try calling some of the adapter manufactors.. ie. Transdap or Weirhotorodproducts who markets a LS1/T56 bellhousing to adapter to SBC/BBC.

The factory service manuals have every possible technical drawing you could want.
I can scan the pages after work

You can do what we used to do in the days before CAD: copy the picture on an enlarging copy machine until a known dimension scales accurately. Then you got it. You can go to @1/3 size or perhaps 1/2 size. Go measure the dimension across the register pins on a transmission for the "known dimension"

wow-thats going to take some pretty accurate machining-not only the bolt placement for the engine, but for the crank center to line up with the transmission input shaft-i wonder if you could use a mill, find the exact center of the cutout for the trans, then use a bellhousing clamped onto the adapter, find the center of it based off the other center, then drill the holes for mtg and dowel holes-good luck, it will be interesting to see what you come up with

Thanks for all your inputs.
i couldn't get the link to work ( http://paceperformance.com/index.as...n=Custom&ID=586 )
milling and finding the exact center wont be a problem but a drawing with the bolt pattern it would realy help me and save me a LOT of measuring and head scratching

I dont know if the 4WD transmissions are better then the 2WD rover 5 speed but I have been through 3 of them with just my little Rover 3.5L V8 in my MGB.

The Range Rover has a 4wd 5 speed auto trans thats been proven to handle the LS1 power.

Keep in mind that the bolt patterns for the transmission / engine interface were designed back when the US auto industry was Imperial Units (inches, always in fractional parts like 1/16, 1/8, etc). Go to www.paceperformance.com and look on their site for "Dimensions" and then "Engine" You'll find drawings there.
