Stock internal 318 redline??

When shifting 1st to 2nd you got .59 drop so 5000 to 2950 or say 5500 to 3245 rpm's even though your probably making less hp at 5500 than 5000 but it's a lot more than 2950 rpm hp, even though 3245 rpm is only slightly better the more time you can spend around peak the better.
Each car is gonna have it own optimal shift points you got to play around. Even if it's just in the streets.
