On the 351 swap, what flywheel would I use since mine is automatic????

 

im not sure what ur asking.. but autos dont take flywheels.. they take flexplates unless ur calling the flexplate a flywheel.. otherwise a 351 flexplate will do the job.. the bigger question is the stall converter. which one u wanna use

didnt see ur other thread that it was replied to ur questions

 

Use a 351W flexplate with 28oz embalance.
