Hi im looking to find what the actual redline is for the stock 5 liter. Ive looked what seems to be everywhere and I cant find an answer for the stock motor. I am looking to get a new carb for an 81 im looking to buy today or tomorrow and im trying to do the cubic inch x redline equation and cant find the redline. Im guessing somewhere around 4500/5500 my 350 in my tahoe was about that. Thanks for any info you guys can give me. Also what are good carbs for a stock motor. Ive heard bad things about edlebrock and holley so im unsure. Thanks
