Ok, I am thinking about rebuilding the engine in my K5 and want to get your opinions on the rebuild. Here are the specs for a 383 stroker....let me know where improvements can be made or where you would do something different. 1. TBI bored to 50mm (supposedly flows 750cfm with other mods) 2. TBI spacer 3. injector spacer? 1/4 inch 4. Edelbrock Peformer TBI Intake Manifold 5. World Products S/R Torquer Cylinder Heads (76cc) 6. stock block decked at 9.000, bored .030 over, clearanced for 3.75" stroke. 7. Keith Black Hypereutectic flat top pistons 4.030 bore. 8. 6.0" scat rods (H or I beam)? 9. Scat 9000 series 383 crank. 10. Comp Cams or Crane hydrallic roller 280/280 cam 11. HEI with MSD module ignition. 12. Hooker Headers 1 5/8 primaries 13. No Cat (no more emissions testing for my truck next year…) 14. DynoMax 2.5 inch muffler(s). 15. stock reworked oil pump 16. new ECM I think my final compression ratio will be around 9.6:1 Questions, 1. Will stock oil pump do? 2. Got suggestions on thermostat? (165 I assume) 3. Think this setup will be too hot for electric fans? 4. Any guesses on the output of this motor?
