Building a budget LS doesn't mean you have to skip out on durability, you can have your cake and eat it too. Sure, high dollar cylinder heads, forged pistons, and stroker crankshafts are nice, but with a few parts and tweaks done in the right areas, a stock based LS can survive quite a bit of abuse. In this episode of 4.8 vs 8.1, we wrap up the final upgrades on the 4.8 LR4 budget rebuild. We check the oil pump gear clearance, measure piston to valve clearance, talk about different options for MLS head gaskets, install the new valvesprings, locators, and seals, and bolt the 864 heads down with some ARP head bolts. The stock intake goes back on after getting a bath, and then we gotta see how the texas speed long tube headers look on the engine. I can't wait to get this 4.8 LS back into the silverado with the new torque converter to see how its gonna perform, and then get it back on the dyno! Do you think this baby 4.8 will be able to take on the mighty 8.1 big block?
