It'll be interesting in seeing your dyno results between the 2 intakes. I dyno'd a 418 stroker using an 05 the truck intake and SRT8 6.1 intake. Even with the port mismatch both those intakes preformed almost identical to the point when I overlayed the 2 graphs I couldn't tell which was which.
That's interesting. Was there an aftermarket cam in the engine you tested? If so, what lift and duration?
What heads were on the engine? Since you mentioned port mismatch I am assuming old style 5.7 heads?
Yes, 5.7 heads. The cam was .578/.588 231/236 @ .050" 114+4
