What info you need? I have a 95 5.0 Roller ... 100% stock. Edelbrock Performer RPM intake and Edelbrock 1406 Carb. I would like to see the current numbers with the Hooker 6901 installed ... and what they will look like when I put the factory manifolds back on. Thanks ...
Dan, Have you ever thought of having your stock manifolds "Extrude Honed"? It is a process that enlarges and smooths out the manifolds inner ports from end to end making them flow much better than stock, I assume you were asking the above question because you would prefer the appearance of manifolds on your car.

my buddy will be in hot rod U in a few weeks, access to a chassis dyno, we'll hopefully be doing a dyno tune relatively cheap
347 10:1 Canfield 195 aluminum heads (2.02 & 1.600) Victor Jr. 750 DP Solid Roller .624 lift, I- 236 @ .050, E- 250 @ .050, 112 lobe separation 1-5/8 long tube headers Thanks
Wow ... quite a difference between headers and manifolds ... how accurate are these numbers in real life? Most articles I have read on the internet show a 5-15 HP gain from headers ...
