That depends on tire height, gear ratio in the rear, and final drive ratio in the trans.
As an example, I had a car some years ago with 26" tires, 4.10 gears, and 1:1 trans that would be running 3000 rpm at 60 mph
On the main bearings, you should fall between .001, and .003. If it is high performance, and you are going to rev it, go .002. Looser will rev.
6500 rpm and 100 mph
Chevy 350's can ussually hit around 6,000 rpms but that's pushing it, youd be better off sticking around 5,500
it doesnt sound orthodox but cut the tach wires to the dash, it worked on my 94 with a 350.
95 mph due to rev limiter in ecu
Anything over 6500 would be rolling the dice.
A 600 carb should work good up to about 5500 rpm. If you plan to rev over 5500, a 750 carb would be a better choice.
231 mph, and with the rev limiter removed 240.1 mph.
carb problem my guess would be accelerator pump or stuck power valves in carb.
Turn off radio and eject on cassette player. Then press seek rev for hours and seek fwd for minutes.
19 to 21 inches of vacuum at an idle, The higher the better. If the engine has a high performance cam then vacuum will be alot lower. When you rev the engine up vacuum should drop and then come right back up.
Is rev limited at 120 mph.
