I aquired a 92 ford ranger that needs an engine rebuild. i bought anouther 3.0 that came out of a sable. I know i will have to swap some of the stuff like intake and exhust manafolds. I want to get the new engine on the stand but cant seem to figure out what size bolt I need. I do know that my 7/16 bolts from my 302 build do not fit this engine.
I'm pretty sure the bolts you need will be metric. To get the correct thread pitch and diameter for the bolts, you will need a sample bolt. You could go back to the place that you got the replacement engine from and ask for any of the bellhousing bolts that they took out. Or you could remove a bolt from the bellhousing on your truck and use it for the sample. Then just figure out how long it needs to be to mount to the engine and the stand. Most hardware stores will have a gauge that can tell you what the metric diameter is along with the thread pitch (number of threads per inch or per milimeter). Grade 8 bolts would be the best for the engine stand. Get some washers for them too so the head of the bolts won't dig into the engine stand mounts.
