Rpm!
Wondering how high folks are spinning up their stock bottom end engines? With upgraded springs (977s) how high is too high? Is it possible to turn 7400 rpm, if not what can you get away with?
How long will things last when things are spun up (assuming limited drag racing)? What fails, springs or internals?
Thanks for your input....

I know some T1 guys that will crank up their rev limiters to 7200 rpm on a stock bottom end, what kind of RPM are you hitting in the traps right now?
When I had my Magnacharger with 3.73 rear and 2400 stall converter I was going thru the traps at 6400 rpm.

6800 RPMs here. Been set there for 3 years no problems. Pushrods would be the first concern. Make sure they are hardened ones. Bottom end would be a concern going over 7000 RPM. If you were going to Road racing I would'nt set in over 6700 RPMs. My .02
