Thanks for the welcome fellas. I live in Albia, IA. It's about 60 miles south of Des Moines. The truck is a work in progress, aren't they all? It's a 4x4 getting a vortec 5.7 installed with TPI injection. So far I've got the 4.3 removed and a dummy engine installed for mock up to work out the physical installation problems. Space is at a premium EVERYWHERE in the engine compartment! So far it seems the engine will physically fit with the radiator pushed fully forward into the radiator support with electric fans. I'm trying my best to use stock OE components where possible so no headers. I think I have the exhaust under control now using LT1 exhaust manifolds but I'm going to have to jog the steering shaft around the manifold on the drivers side a little. Needless to say I'll have to use some after market items for this, i.e, a heim support bearing to stabilize the dd shaft when I install another dd joint. Should work out good. We'll see. I'm also using a stock offset oil adapter from a Caprice 9C1 (cop car). They utilized an oil cooler also. Since the engine compartment is so compact on the driver side with front differential driveshaft, exhaust, and steering I'm using the offset adapter to position a small oil filter closer to the oil pan. Not an ideal situation but there is a rainbow. I'm going to use the 1/2 inch hard lines that ran to the cooler for mating up to a stock oil filter adapter that's located under the radiator support. Basically it will be a dual filtration system albeit divorced. I will employ a couple flex lines in between the two so the engine is still free to move even with the one filter assembly under the radiator support. The only thing I'm not real sure about is the bypass valves in the adapters. Should they be left stock or will any of them need removed????
