Yep,,, if you do the ddp mod,,, on this manifold, you just have to swing into toward the centerline of the manifold with the outer edge of the hole, to avoid grinding thru.... this gives you 2 ''kidney'' shaped holes instead of 2 straight sided holes.... you can enlarge the original holes some also.... this is a 4 bbl manifold but with carefull grinding you can improve it quite a bit...it is not impossible , you just gotta be carefull.....it can be done.... I had a machine shop enlarge the primary holes to the same size as the secondarys on my manifold and it helped the power enough that you could definitly feel it in the seat of your pants....
Bill, Somehow I missed looking up the link you told me about on the st300 tranny. Checked it out tonight, lot of good info. Thanks for the heads up! Michael
