Next...I needed bigger than stock injectors for my HP level....so, after researching them some I found an abundance of 42lb injectors were available for cheap. The stock LS7 injectors are 42 lbs and people change them out when they do mods...so I picked my set up for $78 on ebay. Only drawbacks is they are shorter than standard injectors and have a different connector, so you have to either put FAST injector spacers on them (I bought mine brand new for $25 on ebay)....or modify the edelbrock injector brackets...I took the easy way out and bought the spacers as my brother has used them on 800+ hp engines with no issues. Also, I had to change the connectors out on my harness to the USCAR style connector.
