INJECTORS! 12v help fast
 

I have a 1995 12v that needs injectors, has had the same one in it since stock , it's got 270k on it but it's been kept up on everything, engine is solid. I have done some research on injectors, but don't know what to go with, need something to help pull 5th wheel and race car sometimes. And I would like a little better acceleration. Please help need done soon.
