602 crate rpms

[benjames67]

What realistic rpms can you turn a 602 and expect it to stay together.

[TROUBLE]

6500 - 6700 depending on what oil you use.

If You Do Some Research On The 602 Create Engine You Will Find That They Make There Most Power Around 5500 To 5800 Rpm And They Stay Together.

88958602 GMR 350/350 Circle Track Engine
Great racing power at a reasonable cost (350 HP at 5000 RPM _ torque 390 @ 4000 RPM)
This is a factory sealed crate engine package, complete from high rise dual plane intake manifold, stamped steel valve covers with racing style breathers, and 8 quart single kick-out circle track racing oil pan.

The 350 engine is a great value with the nodular cast iron crankshaft, iron vortec heads with 1.94"/1.50" valves, flat tappet hydraulic lifters, and HEI distributor.

The base engine is a 330 HP 350ci, with the following parts:
P/N 10105123 4 bolt iron block
P/N 14088527 Nodular cast iron crankshaft
P/N 10108688 PM rod
P/N 12361371 Cast aluminum piston
P/N 24502476 Camshaft with hydraulic flat tappet lifters
P/N 12558060 Iron vortec head
P/N 12366573 High rise dual plane intake manifold
P/N 1104067 HEI distributor

Technical Notes: These engines are sealed at the intake manifold, cylinder head, front cover, and oil pan with special twist off bolt heads. The 350 HP @ 5000 RPM was derived from a superflow dyno using a 4 barrel 650 cfm Holley carburetor P/N 80541-1, 32" long by 1 5/8" to a 1 3/4" stepped header with a 3" collector, and 92 octane unleaded gasoline. This engine package DOES NOT include a water pump. Oil pan clears most GM rear steer chassis with stock engine location. Oil pan is 8" deep at sump.

Good job chaser!!!! Ive seen several on the dyno and all of the engines are the same. It suprised me just how even they really are!!! I think the crates put on the most competitive show out there. :dirt_race:

[benjames67]

I know that gm shows 5800 is max hp but on built engines you usually turn them close to a 1000 over that amount. Can anyone tell me real world numbers, and thanks Trouble, I would just like to get a general conscenses before I buy, our track has offered this option in super stock.

[Racerchaser]

Alot of tracks will make you run a chip might be 5800 or 6100 or whatever they choose and it is real easy to check. They pull your chip and test it, takes every bit of 30 seconds.

[benjames67]

we wont be made to run a chip, is the chip required at most tracks that run this motor?

If you go to some other forums you will find that Chris Steele and some of the Fastrak guys trun the 602 6400 RPM's with no problems. I believe I read in one of his posts on 4m that that is the RPM he looks for at a track.
