I will have a 347 Liberator Shortblock -Dart SHP Machined built and these are the cam spec Duration at .050" Intake - 224 Exhaust - 237 LSA - 111.6 Lobe Centerline at intake - 110
I also have a set of AFR 205 hydrolic heads being deleverd today and a new Holley upper/lower intake.

Now I will be ordering new fuel injectors 42 lb, mass air 75-80 new tb 75 and new 225 fuel pump. My question is are these the right size and any suggestions on brands.

I was thinking Pro M for mass air and Holley for fuel pump any help would be great


Thanks

Get a tune, seems 42 a bit much squirt.Tune will adjust.

Ok was unsure and figured I could go a little bigger and get a tune to adjust. And if I understand it correctly cant you also buy a regulator to adjust the presure? This is my first build and have learned alot but still have a lot to learn.

Defenite yes to buying adjustable fpr. set 0f 30lb injectors should cover the need.

ok thanks. Any suggestions on brands?

skip over the 75mm maf and TB setup, and go straight for the 90mm accufab

and you might want to get a TFS-R, or box R... anything with a larger TB inlet

hey, another thing you can do is type in fuel injector calculator on google. those calculators give you the exact number that you need, based on the horespower you desire and the size of your block. I know with my 331, pushing out 415 hp, they recommended 39 lb injectors, (this is because mine is also blown)

I am also running 39# injectors, so when I hit my juice, ive got enough their to support it.

Ok thanks for all the info and tips. will be ordering them tonight, and if all goes well pull the engine this weekend. Then clean up the engine bay and begin my first engine build and install.
