Hereby the details I received when I ordered the engine, sorry if I wrote down less important/irrelevant details

- Chevy 350, 1979 block, bored and honed
- Cast iron precision ground crank assembled W/Tri Metal Clevite 77 Rod and main bearings
-Set of I-beam connecting rods W/ARP Rod Bolts
- Assembled with a set of hand filled perfomance rings
-A three piece true double roller timing set
- A crane performance camshart (hyrdaulic lifte)
- A set of high rev lifterss
- Set of Edelbrock Alu Performance Cylinder Heads With 2.02 Int And 1.60 Exh valves, Scew in studs and Guide planes
- A set of chrome Moly Push Rods
- Set of new performance long slot ocket Arm W/1.5 ratio
- Edelbrock Torker II 5001 Series intake manifold
- Edelbrock 600cfm Carburetor
- high performance HEI distributor
- HIgh Volume Oil pump
- Performance balancer

Judging by the terminology, you have a recon standard bottom end, otherwise I think they would have made more of the description. The top end allows better breathing and timing for performance.

If they have done a good job with balancing etc, I still believe you should be limiting yourself to 5750. Depending on your cam with the inlet etc you would not be benefiting much by extending this anyway.

High performance HEI ? I only know the standard HEI distributor which has its own issues above around 5800 RPM anyway - dont know whether it was down to Spark scatter or not, although I believe that there is a kit which can solve this

All the best.
