i have the scat 4.250 crank for my 390 stroker i am just gathering parts but today i pulled out the crankshaft to try the arp crank bolt wich is for the ford part number 150-2501 it does not fit. does any one know which bolt you use for this application.?

i also have the shelby timing cover and the shelby crank spacer that does not seem to fit also how are these installed is it a press fit i have the profesional products sfi dampner just curious why is the spacer needed
any info would be appreciated. steve
