I hope I am not creating a problem with this inquiry as I had asked in the C4 technical and performance forum with only one reply that did not answer my question as of yet. So I create this inquiry to this forum in hopes of learning the information I seek, perhaps I should of started here first and for this I apologize, I have no excuse but that I am new. My inquiry is that I own a 1984 crossfire and after reading much information I have decided that I want to port an intake for it. I really would like to keep the original that came with the car untouched incase I make any mistakes I can return the car back to original condition. In my search of keeping this car a low dollar budget build I have come across a 1982 corvette crossfire engine and my questions are, besides the different part numbers and different fuel lines I have read about are these two manifolds the same? Is one larger or better suited for my intentions? I do recognize they have different injectors, and I do recognize the difference in the F body car applications, and I am not without mechanical knowledge. Not having the intakes off or even both engines in front of me makes it hard to compare and visualize so I ask these questions. If anyone has experience or can answer my questions it would greatly be appreciated as the 1982 engine is two hours from me and if it will not suit my needs as a donor for the crossfire system there is no point of me going to get it. My car is extremely low budget with my current employment situation, my car came to me at little to no cost and I am a huge underdog fan and always wanted a crossfire for the challenge and also becuase in my experience most cannot make them run correctly. Thank you to all in advance for any effort you may do to assist me.
