scoggin dickey sells the LT1 and LT4 stock grind cams. why are they on rated to make power idle to 4500rpms, i thought the 92-97 LTx series engines made good top end power and red lined around 6k? the reason i asked was because i plan on rebuilding my 305 soon and i was happy with the results of the stock LT1 grind cam (95) and i was thinkin maybe id swap in a stock grind LT4 cam when i do the rebuild.

LT1:

LSA: 114
201/208
.447/.459

LT4:

LSA: 115
203/210
.476/.480

think i should, or would i be better off with a 2032HR cam, zz9, zz4? or just stick with what i have. ive even had crazy thoughts of putting together the 350 i have

 

redline is only a function of safe RPMs before parts start to break

Redline does NOT mean the peak of your power curve

 

Comp 07-305-08 .510/.520 220°/230° 114° LSA

It produces torque well beyond 4,500 RPM in an LT1, I guaranty. It may be a little much for a TPI, however.

 

is it true that these cams are rated to 4500 only? i question this because the only cars ive heard about falling off at that rpm is the TPI inducted engines. ive never heard about an lt1 with soggy top end.
