New 383 Build

This is my first post here.. looking for some good feedback hopefully.

Let me know what you guys think about this BUDGET engine build to go in front of a 700r4 with a 2500 stall converter. We are just about to put this guy together and drop it in a 77 step side.
  • Air Gap Vortec Intake Dual plane
  • Vortec Heads - 64 cc chambers/170 cc intake runner- 1.94/1.50 valves - .525 lift perf springs 110 # on the seat and 295 # open - Viton positive seals - 3 angle valve job
  • Clevitte rods and main bearings
  • 3.75 stroke crank 350 mains
  • block bored .030 over with torque plates for proper cylinder/ring seal
  • 383 stroker hypereutectic flat top pistons- right at 10.3 to 1 compression
  • Hi Volume oil pump
  • hardened steel shaft with pinned steel oil pump sleeve
  • Cloyes double roller timing chain
  • .488 / .488 lift cam with 234 degrees duration measured at .050(actual lift is .520 with 1.6 ratio roller rockers)
  • Pro full roller rocker arms self aligning for vortec heads
  • chrome molly pushrods - 4130 steel
  • crank rods and pistons spin balanced to plus or minus 1 gram
  • Pro Comp hydraulic flat tappet lifters
  • AC cam bearings
  • Pro Comp performance 65K volt distributor
  • Block clearance at oil pan rails and bottom of piston cylinder for stroker assembly
  • Cam degreed in straight up - no advance or retard
  • Holley 750cfm Double Pumper

If you think I should make any changes or missed something now is the time before we install. Remember this is a BUDGET build, cost is a factor. Thanks for any help.
