i blew my engine a month ago so i got it rebuilt and also did a bore wich was .40 over.
i go to take it out on the street sounds great, and gots alot of compression.

the only problem is i feel it has no power, as if the power band dont kick in.
any1 got a clue to why its acting like this.
i do got all the mods i need to run .40 over.

 

What kind of mods do you have to have to run .40 over?Did you add these mods when you rebuilt your motor or were they on there before the rebuild?

 

You dont need any mods to run .40 over. If you changed anything from before when it ran good than change it back and see how it does.

 

yeah and why didnt you just bore it .20 over was it a bad scor in the wall?
you shouldnt even need to change the jetting to bore it

check your compression and make sure you have the right octane and that its not bad gas

 

Do a compression test and post the numbers.
