[FED 387]

How many passes barring any unforseen breakage could one reasonably expect to get from the driveline on both a Stock and/or Super Stock car???? Now we are not talking hi maintanence cars like Hemi's or what not OR LO maintanenece cars like W/stocks etc., but the typical car you see in the staging lanes..--- I mean how long does an engine last before you have to feshen it up--likewise with the trans or rearend???? Rings and bearings plus valve springs/valve jobs or honing the blocks what could one reasonably expect to get???? Thanx in advance for your answers --------------Comp387
