It took me a while to find this pic again, I admire your efforts! What is the cross-section of the runner in the plenum area? What is the runner length? What is the trajectory into the head? Does it match what the engine wants? Etc. Also when it's done how ideal is the height in relation to the scoop you want to use? That's why I offer that if a guys willing to do the work, there are better foundations to start with that may not be any more expensive in base material and/or time. Can you explain differently what you meant by the 'only lost 60HP'? Whereas another manifold was 120? What RPM theoretically should the 'long-block' peak at? THANKS!
