[DeTomaso] Intake for 2v heads

[P. Rimov]

Dan ,I have ran both a Performer 2v and a Weiand-X on my 2v Aussi headed 
10.25:1 .531lift/268/276duration engine. The Weiand-X is better for top end 
but does not start flowing well until about 2500-3000 rpm. It will allow the 
engine to make more overall power. The ports on the 2v Weiand-X are still 
larger than 2V heads and require a little bit of porting on the head to 
match.  The Performer is done at about 5800 rpm but has much better low end 
performance and drivability around town. The ports are much closer and you 
can get away from having to port match the heads but is still a good idea. 
In my opinion neither manifold is great when cold and the Weiand took a 
little more fussing with starting when not driven for awhile. If I put the 
Cleveland back in some day it will be with the Performer and some form of 
fuel injection and the Weiand will find a new home... I am sure Dan Jones 
will chime in on this thread as he is a big fan of the Weiand-X over the 
Performer. And I believe Dr Engles also has used both manifolds as well. 
Lastly, both manifolds benefited with the use of 3/4 to 1 inch carb spacer.

Cheers

Paul
