My next little project was to get an LT1 intake manifold and swap from my L86 intake. Some of the truck guys use this setup with their stock truck accessory drive and I got a few pointers from them that I'll share. First off the TB is upside down when compared to the LT1 position, they did this I'm assuming because the TB motor hits the water pump when you try to mimic the LT1 position. You must run it in the stock truck position and to accomplish this you need to clearance the TB motor and in my case, I also had to clearance the alternator slightly. I just used a Dremel and test fit it a few times until I got the results I was looking for. The TP harness plug is a tight fit but does not rub. Another issue you run into is the belt contacting the intake tube. To do this you must add an additional idler pulley to the alternator mounting bolt and wrap the belt below it thus pulling the belt below the intake tube. Requires a longer belt too. If you plan on doing the swap and want to use the factory style PCV tube from valley cover TB here is the correct PN in the photo below. If you try to use the L86 hose it will kink (very long in secont pic), the LT1 hose is shorter (last pic).

You can find these intakes on here or craigslist for around $100. I scored mine for $60 and sold the L86 for $80, made out like a bandit

I'm basing all this and other upcoming changes to me using the stock truck accessories (for the most part) and running the Kwik Performance L86 bracket to run PS and high mount AC on the PS side. This is the only accessory drive I know of that will allow me to run the factory vacuum pump (one goal I'd like to make) and not break the bank and spend $2K+ to get things going. The Kwik setup is around $500. See link below. Wayne at Kwik also said he can equip his setup with the additional idler pulley to run the LT1 intake and sent me a few pictures of another customers setup.
