what size fuel pump for this combo?
 

I am finishing up my ne keith craft 306 with trick flow track heat heads, trick flow stage 1 cam w/ 1.7 roller rockers, tfs street intake, bbk long tubes, etc. I am going to be using 24# injectors but am not sure what fuel pump i should use. I have a 255 lph sitting around. Is this fuel pump too big for my combo? If so what size should i go with a 190 lph? Thanks for the help in advance!

The 255lph pump is serious overkill, but if you already have it, I suppose you can use it. It will run a little hotter than normal, but it won't cause any catastrophic failure of any components.

It will allow you to run N20 or a blower down the line.

Do you have an Adjustable FPR? If you do you shouldn't have a problem if you just turn the pressure down. I'm not sure on this just a thought.
