What size of injectors?

[lefebvrn]

I am new here at stangnet. I got to say this is the best site on the web. I am currently building a 331 and I would like some suggestions on what size of injectors to go with. I am undecided beween 24's or 30's. I am going with a pro-m mass air meter. Plus I would like suggestions on what size of throttle body.

30s, 75mm, and a custom tune.

Thanks for the input. I will need to start looking for a shop that does tuning in the Sioux Falls, SD area.

24's

36# injectors. Pro-M 80mm. Dyno Tune.

30's with a tune, the 24's will be maxed out

Could I get the car running fairly good with adjusting the timing and fuel pressure. Then take it to someone so they can get it dialed in. Or do I have do some stuff with the computer along with timing and fuel pressure?

it will run decent w/ a matching MAF (75mm+) and good fuel pressure. Its always a good idea to go get a custom tune though. That looks like its gonna be a nice n/a motor you have there. Who is building it for you?

I am having the shortblock being built at a shop in Sioux Falls. This guy builds most of the engines for the guys who race circle track around the area. I am going to do the rest of the work with some help for my uncle (to bad he is Chevy guy). I was hoping I had a good combo. I did a lot of reseach in these threads. I want the old Chevy guys to respect a 5.0 alittle more.
