Looking for machine drawings of Chevy heads


Recommended Posts

Hello gents! hopefully you guys can help me. I'm in the process of installing a vortech supercharger and I want to make an Air con/alternator bracket for the passenger side. I tried the cardboard and hammer method but the accuracy is not that great. I looked on the web and couldn't find any machine drawings of the accessory bolt holes for the SBC heads! does anyone know where I can find some? Thanks!!!

well guys after looking through the web for 2 days straight i finally found just 3 pictures of the bolt holes that I was looking for! I can't believe that the SBC been in production since 55 :blink: and I could only find 3 pix? Well here they are just in case someone needs this info later. The march diagram is kind of what I want to do, but the A/C is too low and will hit the passenger frame rail and the motor JTR motormount. So I need to mount the A/C higher up , almost to the same height as the alternator. the last pic is my pattern for the Vortech supercharger. wish me luck guys! :rolleyes:

Now I'm trying to figure out how to get the huge Vortech carb box to fit under the hood? Any ideas?

 

It looks great. Welcome to forced induction.

When I had an airbox for my turbos, I lowered the engine for stock hood clearance. If you don't want to do that, but want the stock hood, maybe a carb hat would provide clearance.

Hello there Turbo Meister! It's been awhile since we last saw each other! Yah, I finally saw the light and decided of forced induction! I do want to try to keep it all under the stock hood. Ill try lowering the crossmember and see if that's enough. As far as i can figure i need 1 inch. ;) Im so close now I can taste the track!!!! :D
