    Motor Swap!

    Well guys I started the motor swap going from 4.3L to 5.3L. I pulled the v6 yesterday and I get to pick the 5.3 up tomorrow. Can someone tell me how to convert the fuel rails because I really don't want to buy all new fuel rails.

    You can go on summitracing.com and buy foot long braided fuel lines. When I went 4.3 to 5.3 I removed the lines from the rail. Measured about 8" down from the beginning of the rail, and cut the rail off. Then I used AN fittings, and the foot long fuel lines to hook up to my stock rails. Been runnin trouble free since 07
