99+ intake mods?
Posted: March 30th, 2015, 2:55 am
Is it possible to modify the late "curved" intake manifold for a 4 barrel carb?
Is it room on the top to get a mounting pad welded on there and if so in what direction would it work best for flow and distribution into the runners?
Asking just because I think that the 99+ intake manifold is the closest we can get to have a "tuned" manfold,the Offy intake I have is really a nightmare in terms of even distribution to all cylinders, 1 & 6 seems to be lean,2 & 5 is almost good and the 3 & 4 seems to be very rich when looking at the combustion chambers and sparkplugs on my old head,the 99+ intake looks like it would work better with almost equal lenght runners going in to the plenum seperatly and not like the Offenhauser that is divided only the last 4-4.5 inches.
Has to ask here since it's not that common to find an intake here in Sweden,so for me to go to a salvageyard and pick one up just for messuring is not that simple,it took me almost 3 years to find a HO head that was for sale,and a intake won't be any easier i think,but IF it's possible to modify one atleast it would be some sort of meaning to search for one...
