I have a 347 stroker I'm putting together...It has trick flow heads, edelbrock victor intake, 70mm thorttle body, 80mm mass air, and 42 lb injectors...This stuff is off my old supercharged engine...Would this be to much for a natural 347?

A tune may help with drivability though...

I would htink that 42 would be a little too big. That doesn't mean that you can't use them... it just means that it may be rough at idle or in the lower RPM range unless you have it tuned properly. In order to smooth it out, you really need to make sure you get the high slope, low slope, and breakpont worked out. When it comes to smalelr PWs, it can be a pain in the *** to work out at times.

i had to get a tune with my 42s and my 60s

Yeah. From what I have seen, injectors tend to a little extra work at anything larger than 30#. And the bigger you go, the more precise the tune needs to be. At least that is what I have seen.

30-36's would be plenty, 42's wont hurt a thing
