[QUOTE="Robert M, post: 16533684, member: 9628"] Years ago, actually late 1999 I was involved with Mustang Monthly and a magazine feature called "Big-Block Blowout". It put 4 or 5 totally stock, some restored, some original big block Mustangs on a chassis dyno to see what real world numbers were really happening at the rear wheels.......There were 2 428 Shelby's (1-CJ and 1-PI), 1 390 GTA, a 70 BOSS 429 and my 1971 429 SCJ. In the end I pulled the best rwhp while black smoking (rich) from 3K on through 5K. The other Mustangs ran very clean through the chassis pulls, but I managed to beat all of them with cast iron manifolds, oem solid cam and dual point, and factory D1Z Holley 780cfm and functioning smog pump. It was a fun time but it also pissed off some of the Shelby owners and the 70 BOSS9 guy was also pissed! Jeff Ford titled me the "Big Kahuna" in the magazine. I ended up coming back in 2001 for a "test and tune" on a chassis dyno in a Mustang Monthly feature called "Dyno Tuning for Power"......My rich/black smoke problem in the original "Big Block Blowout" feature was the oem Ford Shop Manual size 83 jets in the rear, when the vac. secondaries would open, 83's were wayyyy to large, the 71's up front were fine. I ended up downsizing the secondary jets through a couple of pulls and got an additional 50 rwhp out of that old/original unrestored low original mile 1971 429 drag pack Mach 1, the magazne feature for that dyno tune is linked below.....
