Default 87 Indy 400 top speed of 50mph

Hey new to the site and looking for some help. I have a 87 Indy 400 L/C it won't go above 50 mph and it's really boggy when wide open. sometimes worse than other times. No matter what i do to it. I have cleaned the carbs again and again put it back to factory jets (at least from what i have read) (220 main/35 pilot) it should be rebuilt because the compression is 100 psi and 90 psi the other I'm lost I guess my question is could the low compression cause this? I feel even with those numbers it should run better. What else could cause this?

Thanks for the help
