For a n/a 8 cylinder engine, 42# injectors will support 550 FWHP on gasoline at 80% dc and 675 FWHP at 100% dc.

I'm running those injectors on my 408 with LS3 intake and P/P LS3 heads and put down 475/475 and they work perfectly

Its a fast 102 and a 408 long block from Thompson motorsports. They are ls3 heads. And yeah no giggle gas. For now maybe a small 75 or 100 down the road just depending on track times and yes pimp gas 93 octane
