I got a 190 lph pump. I would just say get the biggest you can dig up, but I am a fan of the 190+. The 10 dollar price difference is not really worth compromising on.
Ok, I will tell you for the combo you are making you do not need 24# injectors unless you just want them. Thats basically why I got mine but I seriously think I wasted my $ at this time. You can and will acheive your goal of getting into the 12s without 24#s. My way of looking at it was it was better to put the money into the motor up front and do the little external stuff later. Nothing cracks me up more then guys on here and on the base with stock block, E7s and intake and a 70mm t/b and 76mm mass air ect because they are about to bust loose any minute and put that blower and AFRs on. Yeh, ok, meanwhile I am actually running faster. Oh no, I dont have an MSD yet either, how is it even getting down the street?
BTW, I have been happy with my ported 289 heads for no more money then I have in them. Its all about $ versus what you want out of the car. If money wasnt an object do you think I would even be playing with small blocks anyways? NO. I can tell you there is a lot more left in my car right now. I ran 13.30 with the clutch slipping, Kumho street tires, and the stock fuel pump, meter and injectors and 3.55s. It was really starving for fuel and the next week I put that 190 in. I was a believer, the power was insane for just one part, so yes, it was running very well despite a fuel pump that was way too small. I'd do the pump up front, get the injectors when you get to it.
So, yes, I would put that motor together first how you want it, then if you want to get 24s later, go for it. Thats what I did. When I first got it together, I only had headers and open H pipe. I fixed that pretty quick but this is a rolling project.
