Red Line?

[Lobo'74]

I have no idea what my redline is. I need some thoughts from y'all on what is a reasonable redline to use. I want to use the engine up to its potential, but don't want to overrev it either.

PO said he guessed it was about 6000. I don't take it above 5000 now because I don't know what it is. Its very strong and would pull well past 5 grand. Specs for my '79 4 bolt main 350 are:

Note: For correct tune-up parts, such as spark plugs, cap, rotor, coil, plug wires, use parts made for a 1979 Chevy C10 pickup 350 Cu in. engine. This also applies to accessories such as the alternator, water pump, thermostat, radiator, clutch disk, pressure plate, throwout bearing, and transmission. The power steering pump and gearbox are from a 1985 Chevy truck.


I think it is over carb'ed with the 750 cfm. When you stand on it it initially bogs down for a second then revs up. I think it dumps more gas than the engine can use until it really revs up.

Any thoughts on this too?

Thanks.
