Default help me finish my build

FINALLY got my motor back in my car thank god. Anyways here is the last of my questions.

Car is on stock injectors for now, in 800 miles after easy break in im going to put new injectors and a walbro in it for safety, but i dont know what injectors i should pick.

Beginning of summer car is going to get heads. I havent picked which ones yet, was thinking of the PRC Termi's, TFS 215/225s, or maybe the new PRC 215s if they are out by then.

Car currently has MS4, Melling oil pump, hardened pushrods, ls6 intake fully forged bottom end Full exhaust blah blah

plans: Injectors of unkown size, UD pulley, either a fast 92/92 or the new edelbrock (if i can get my hands on one), SD tune.

question i have is what injector size and would you recomend new rockers/lifters? currently have brand new stockers and am worried about them being the weak point in the car.

Car is an M6 about to get a new 9" with 4.30s it is also going to be a max effort track/weekend warrior car as i have another car to DD to work and school

Are you planning any other mods or nitrous in the future? With the upcoming mods, I would recommend at least Ford 30lb "red tops". You could opt for the "green tops" and have room to add more airflow mods or nitrous.

You will be fine on the stockers, although Harland updates the bearing.

42# injectors should be good, any n02 in your future? Lifters... I used comp-R's when I built my engine and they have been great so far. Rockers... I'm still on my stockers too, they are the only thing left from my original engine lol. So maybe some one else will chime in. One more thing get new plastic lifter trays when you drop in the new lifters. TSP sells them for like $3 a piece.

i plan on revving it till it runs out of power, which im sure a MS4/top of the line heads will be 7K+. Nitrous maybe in the future but it will be at most a 150-200 shot.

When we re built the motor we did put new trays in it. I have just always seen the terra yellows so thats why im asking these questions

thanksguys

I would have to agree. I think anything thats going to flow 32+ at our fuel pressure should be enough.

I would think about the PRC215 for sure. They look very promising.
