I was not planning on straying too far from stock. After all 360 hp should push the bird down the road nicely. The information you gave is exactly what guys like me need. You have already built an engine like this! I had already made my mind up about the long branch manifolds. I do remember the quench discussion and made notes on that. Head selection and how to put it all together without ending up with mismatched parts is inportant to me. I am starting my lisst for the machine shop. Thank you again for your time. I will be out in the pole barn today tearing the engine down. I have an edelbrock performer on the 350 in the car now and the engine came with the factory cast iron one. I plan on adding the ram air pans to the car so I need to know if the edelbrock manifold is the same height as the factory one? I am leaning toward the fastory one. The purist are getting to me! I also have edelbrock carb in 600 and 750cfm. Which would be the right size for a build like this?
