What size MAF and TB? And what injectors?
Hey I have a 331 w/ 10.1 compression with GT40P heads and TFS Street heat intake. What size MAF and TB should I get? I know you dont want it to big and I dont want it to small where it will restrict flow. And I think I have heard you want one smaller that the other or something but not sure what one. Please fill me in. Thanks

well 70mm is fine to gow ith to support your future mods, maf 75mm is fine. as far as injectors thats a totally diff story, 24# is good up to about 350, so if your going to go with more hp then that soon and nos soon id look at 36# or 42#, your also gonna need a bigger fuel pump if your going to spray.

I am not sure what cam i am gonna get but it will be fairly mild, somthing like a TFS Stage one or something similar. It is going to be almost all street driven. I think I will go with about 36# injectors, 70mm TB and 75mm MAF. Does that sound good?

i believe the trick flow street heat intake inlet is 75mm so get a 75mm TB and a 76mm MAF, 42 lb injectors with a walbro 255lph in tank pump, and adjustable fuel pressure regulator. might as well go bigger with injectors and use less duty cycle and pressure from the pump than be maxed out on a 100% duty cylcle especially if your spraying....
