Stock 89 5.0 auto upgrades.
I have a 1989 5.0 auto convertible. I'm looking to do a few upgrades in the quest to get into the 13's in the 1/4. All the car has is a cat back everything else is 100% stock. I'm looking to ad a CAI, 4.10's, Long tubes, E303 cam and possibly a performance valve body for better shifts. I have never run this car down the track but I'd guess it does high 14's? With this list would you think 13's are a reasonable goal?
