So a friend of mine says,"You're going to go through all the hassle of pulling the engine out of this thing to put on new heads, intake, headers, a manual trans swap and your going to put the 307 back in when you have a roller cam vortec 350 sitting there that just needs a few parts and will give you probably 100hp more?" Ok, guess that doesn't make much sense. So I ordered the engine rebuild kit and a GM Performance roller cam today and got the block cleaned up. vortec.jpg
Got my engine put together and installed along with the clutch pedal for the manual trans swap. Hopefully be ready for a test fire in a week or so.
I had a question regarding the vss input to the pcm; is the optical pickup on the back of the speedometer the same type signal as the NV3500 VSS? The trans is from a 1992 truck. I'm wondering if I can use the VSS in the trans as the input to the factory Astro speedo buffer in place of the optical sensor or do I need to swap the buffer out for a later model DRAC? I want to make sure the PCM is getting the correct vss signal.
