Does anyone know, or has anyone tried, Using the 5.8 lower Professional Products (typhoon) manifold for the mustang and using the stock truck efi Upper. The gaskets appear to be the same, but I am looking at them online. Are the bolt holes in the same location?

Im thinking if this works it might be a cheaper way to get a little better flow out of my lower manifold and not sacrificing the longer runners of the top (TQ).

Any info would be appreciated

 

No the parts won't mate.. bolts holes don't all lineup. There isn't much difference in total runner length between these two intake systems anyway.. only about 1" by my estimate(I have a complete Typhoon for comparison) so they are both essentially tuned to the same rpm range which is 0-5000rpm give or take.

 

Thanks for the heads up. I guess what im trying to avoid is having to much cam and to large of head (Pro comps) and the manifold not being able to keep up.

 

The heads are flowing above 225cfm. the cam grind is custom from comp, with the idea that I would have been running the edelbrock manifold. I was just trying to find a more cost effective solution.

 

The Pro products Typhoon is a copy of the Edelbrock Performer so the two should produce identical results, and at about $400 for a complete Typhoon you can get a matching 70mm TB and have a complete induction system for less than the cost of the Edelbrock. But... what rpm range does your cam target? If it's not a 0-5000rpm cam in this displacement then you need something bigger like a TFS-R.

 

The cam is a custom grind and should be mostly productive between idle and 4k making max numbers at 3k. I can attach the grind if it helps. So if i was to go with something like this Conan, is there a resource for the linkage issues or tps wiring. I have been searching forums to see images or DIY for this.
