Re: 5.3 LS truck motor
I bought one...had in punched out to a 5.7 ls1. Installed forged piston and rods, PRC heads ETMC comp cam. Going to install a magnacharger. I'm hoping for 550 to the hoops...the long block..I have 5100.00 in it...I kinda over did the block...should be able to hold 800-1000 horse though..better to have it and not need it, then need it and not have it.
69 x-11..LS1, 420.88 horse to the tires,750 Holley Ultra DP, Torquer V2, darksides headers, PRC heads, 10.8:1 compression, forged bottom end, 5 speed. 2008 King Ranch F150 4x4.
