i guess i will start off by saying i got my motor back together today. i lifted my head awhile back so i had to put studs in and along with that i had the head o-ringed and milled down. also while i was into it i put 60lb valve springs (im planning on putting a 4k kit in it in the next few days) and new 50hp injectors. i got it all back together and fired it up and drove it around, it is running pretty ruff and is also dogish. i guess my question is why do you guys think its acting like this? i was thinking it might be because of the new injectors and also because its been torn apart and just needs to be ran and i guess broke in and cleaned out a little but i really dont know so any input and ideas form you would be great!

sorry for the long post and thanks for the help

 

it should be broke in just fine. sounds like a fuel problem. what injectors did you get? did get the correct washers for the injectors? did you double and triple check everything?

 

Timing might be off

 

check for small fuel leaks sounds like there is air in there somewhere
