SBO Stroker 380 assembly and details
After a bit over 2 years of chassis resto / mod ( a before and after pic), time to start down the home stretch. Much thanks to the many helpful folks here. ESPECIALLY Mark ( CutlassEFI)- he has replied to probably "countless" emails from me and replied with expertise- can't wait to hear the cam you ground for me! Anyway, pics and details forthcoming.

The bill for all the crank work ( balanced, indexed, under ground and stroked) was a bit under 700$

You shouldn't run those stock head bolts with aluminum heads. You should use good ARP bolts or studs with hardened washers. Directly from Edelbrock:


Head Bolts or Studs: High quality head studs or head bolts with
hardened washers must be used to prevent galling of the aluminum
bolt bosses.

Looks great but I agree with Chadman, ARP bolts are the only way to go with aluminum heads.
