Thanks! It’s my understanding that a 904 is generally a tenth quicker than a 727, all else being equal. Have a regular stacked plate cooler that works fine.
My old stock stroke 340/W2 combo would only 60 ft. in the 1.7s but it seemed typical for the 12.0 ET. I hope I can get down into the 1.5s or lower with the current setup.
The 340 had a Victor W2 and it was definitely lacking in the torque department. 3,500 rpm converter and same 4.10 gear though it could have used at least a 4.30. I shifted at 7,200. Stock stroke.
