LQ4 injector recomendation I have an LQ4 with a TSP 228R cam and the FAST LSXRT intake and 102mm TB in an older muscle car.I am using the 243 heads for a bump in compression.I will have 1 3/4 long tube headers.In searching I see the stock injectors are likely to small to be efficient.Harness ends not critical as I have not bought a harness yet. What is the flow rate that would be required for 400-450 hp.I do also have the FAST rails so I assume I have some choices on injectors.i have heard the 8.1 injector is a inexpencive upgrade.
