jpfll 11 Report post Posted November 26, 2020 When i installed my engine i used the Ron Morris mounts to move it back and towards the passenger side. Now I’m trying to mock up a ram air setup and would like to know how far the center of my engine/carb is from a stock 69 428CJ I took the following measurements Carb stud is approx 13.5” from the cowl - 20” from the inside of the passenger side of the engine compartment and 20.5” from the inside of the driver side of the engine compartment Would someone with a 428 be willing to take the same measurements so i can compare how my engine/carb sit relative to the 428? It would be interesting to know the measurements for a 351W too just for comparison sake. Thanks, Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted November 26, 2020 I've got a 428 CJ shaker on my 351W. The scoop just clears the rear opening of the hood with the carb stud at 14-7/8" from the cowl face. Another quarter inch forward would center it. My motor is centered side to side for the shaker to be centered. Edit: The reason my side to side numbers are different from yours is I measured side to side from the fender edge, not the inner fender. Quote Share this post Link to post Share on other sites

jmlay 80 Report post Posted November 27, 2020 The shaker has some adjustment with the 3 screws that mount the scoop to the midplate. Quote Share this post Link to post Share on other sites
