rb I am looking for the bellhousing bolt pattern for the back of a 401 engine block, along with the crank centerline. I need to make an adaptor plate to run the engine on the dyno, and cannot get my hands on a bellhousing to reverse engineer the dimensions to get something cut on a waterjet machine. Can Anyone point me in the right direction? thanks, rb
ironman_gq can you use the back of the block to get your dimensions. Should be the same as measuring from a bellhousing.
rb In the past, for the oddball engines I cannot find a blueprint for, I just get a bellhousing and put it on the mill, then using a finger type dial indicator, I go to each bolt hole and dial in the centerline in relation to the crank centerline, using the digital readout on the mill, it is a piece of cake. I would have a hard time fitting a block on the mill, in the standing position, and on top of that, the engine is already together. It was suggested I ask here, as I was told there are some sharp AMC engine specialists here... one in particular 69bubblefender I think is his handle, rb

milnersXcoupe That blueprint would help me out as well!:lo1l: As I understand it - a 4.0 JEEP bell housing fits the AMC V8 cyl.block - . :-|
milnersXcoupe ironman_gq wroteI think your thinking the 258 AMC bellhousing 4.0 bell bolts to a 258 - have to compensate for the convertor depth tho.
