I'm Awesome
Most of you have probably already seen me post about this in other threads, but I'm going to start a new thread specific to this part of my project.
I have a TBI block with roller cam provisions that I'm swapping Vortec heads onto, and will be retaining TBI with it. I've read some posts on Camaro forums mentioning that it's apparently a somewhat common swap to put a factory LT1 camshaft into a TBI/TPI 350 engine, and they're mild enough to play fairly nicely with them for just a little more grunt. I'll have to actually get hands on with it to understand this better, but there's supposedly just a dowel pin of some sort you can drive in on the LT1 camshaft to make it fit into other 350 blocks.
I also have a 1993 Camaro LT1 block just sitting around with no plans for using it, so I'd like to pull the used cam out of that block and reuse it in my truck's block (granted it's in good shape). The plan is to take the retainer hardware, rocker arms, lifter rods and lifters out of the LT1 along with the camshaft itself and reinstall them in my truck engine in the same locations.
The first question I've run into (and there will probably be more): do I need to run the LT1 valve springs with the camshaft, or will the Vortec OEM springs work? I noticed that the part numbers for the springs are different between Vortec and LT1 engines, and I think the springs for the LT1 heads are taller. One of the videos I've watched to learn more about working with Vortec heads mentioned that the guide bosses in the Vortec heads typically need to be modified at a machine shop if larger springs are needed. Will Vortec springs be able to work well with the LT1 cam, or will I have to get this modification to transfer the springs from the LT1 heads to the Vortecs?
