I'm trying to collect all the information for engine mount isolators for Rockets and coming up short.
John Harmon calls for Lord p/n J-9613-12. Period.
Mark Frederick calls for Barry p/n 94011-02.
A Google search indicates these two p/n's are equivalent.
Good so far; but I know I have heard and read that there is another Lord p/n for a slightly stiffer isolator often referred to as an "aerobatic" mount. This specifically is what I'm after. I have a hot-rod motor and think the "aerobatic" isolators will be better suited to the bigger horsepower.
On top of this, I've seen that a Piper Malibu (turbocharged) with 300hp uses Lord p/n's J-7763-23 and J-9612-8. This is a similar horsepower to mine but angle-valve (heavier) than my 320hp parallel-valve. I've seen a lot of Lord installations that use 2 different isolators; and switch their locations for the upper ears vrs lower ears. Are we using the one isolator for all 8 positions ??
All help is greatly appreciated.
