Thank you for taking the time to post a reply!
I guess I was just dreaming.
LT-5's have hydraulic lifters anyway, my guess that anywhere north of 7.5k rpms for any lenght of time would invite trouble....eventually....maybe..
Eh, who knows...maybe at Carlisle this yr I'll get lucky and find some one selling an early top end that I can have dunn up.....swapping a plenum + I/H's ain't gonna take that much time.....I'm a member of the Knights of the Plenum Pull!
