Hey dudes, I need to know the bolt sizes from toploader to bell houseing and form the bell housing to block.
Anyone know this, or where I could go on the net to find out?
The bellhousing takes 2 ea 3/8 X 1 1/2 inch and 4 ea. 3/8 by 2 inch course threaded bolts. Don't forget to put the plate on the back of the engine before you install the flywheel. I don't remember what size the Xtrans bolts are, but I think they are larger than 3/8's, maybe 5/8's or even 7/16's. Go to any hardware/fastener place and buy a plastic bolt guage, which also has threads per inch. You could also measure the bolt holes for sizing. They are all course thread.
All bellhousing to trans and block bolts are 7/16" NC. Can't tell you the lengths as they vary on the bell to block side. I can tell you, you want them to thread at least 1/2" into the block, including the 1/16" for the block plate between the bell & block. The trans to bell bolts need to thread nearly all the way to the bottom on aluminum bell housings. They're something like 1-1/2" to 2" long.
