1965 Ford Mustang GT Coupe 289 V-8 - Triple Deuce Coupe
A Standout Pony Meets Standout Induction
Six-Pack to Go
While triple two-barrel induction was a factory option on early-'60s 390s and 406s, such was not the case for the Windsor small-block. The Ford parts counter was where such gold was mined, though the rarity these setups represent today indicate they didn't generate big sales numbers. For specifics, we turned to Michael Brattland's informative Tripower Technical Bulletin, a 60-page publication chock full of pictures, schematics, part numbers, and tuning techniques for Ford small- and big-block triple deuces. The publication can be purchased for $17 through Brattland's web site, www.gerlecreek.com, which is a nice resource itself. Based on magazine ads, Brattland believes the small-block tripower was first offered during 1964 for the paltry sum of $210. Officially referenced in Ford advertising as one of the Cobra kits, the "three 2-V induction kit" for small-blocks had plenty in common with its FE big brethren, including reverse-facing Holley 2300 series carbs, identical carb spacing, and thus commonality among air cleaners. Throttle linkage and fuel logs were engine specific, yet both setups employed a progressive mechanical engagement which operates the center carb during normal driving but pins the end carbs when the throttle's nailed.
Airflow is a key difference between small- and big-block tripower carbs, and as it turns out, there were two small-block variants. Kits designed for the 260ci engine had a combined airflow of 730 cfm, while the 289 version on Lennartz's ride flows a total of 775 cfm: 265 cfm for the primary center carb, and 255 cfm for each outboard unit. For comparison, the '61-'63 FE triple 2s typically flowed 1030 cfm: 330 cfm for the center carb and 350 for each outer.
