Bolt sizes to use on 351W February 05, 2010, 09:24:46 PM Well I finally have time to start working on the 83 tbird again. However I have a slight problem. I want to get my 351W bolted up to my engine stand but I lost the bolts to bolt the engine up. Does anyone know the bolt sizes, grade and length you would use to bolt a 351W to an engine stand?Thanks Quote Selected
