Outer Limits 4x4 Board

Hi has anyone used the Bellhousing Conversion that Castlemaine Rod Shop sells?( Part No. BH78 www.rodshop.com.au ) Its to put a Chev SB or turbo pattern Holden V8 into a GQ... I spoke to them and was told it is designed to use the Nissan Clutch Assembly all you need to do is get the Chev/Holden Flywheen drilled to take the Nissan Clutch.

My main concern is, What is the clapping pressure of the Nissan clutch with the STD 10.75 inch Clutch plate compared to the Chev 11 inch Clutch?

or do you think I could use the Nissan Clutch Plate (10.75") with a Chev 11" Pressure Plate? I wonder if the clutch fork will have enough travel to
engage and disengage the Chev pressure plate? I think the nissan throw out bearing will be big enough.

Any thoughts

Im of the opinion that the chev cluth is the way to go, there is a 12" clutch available if this will fit. if i was to do it again i would use a import turbo 700 auto from a 4x4, as this would not need a convertion for the bell housing, or the main shaft change, only the engine mount kit and the transfer adaptor,
if i was to use the 5 speed i would look hard at the largest clutch available, I have a rebuilt heavy duty GU 4.2 turbo clutch and it still is not that great, it does the job but it is not as heavy as i would like, i can still get it to slip if it is not not totaly engaged when the power comes on, and this is with the diesel, the petrol would be worse as it has i higher power out put,
cheers Phill.
