When a H.O. dampener is retained, to run a 302 H.O. engine in a "67" Cougar in place of the stock "68" 302 wedge engine while retaining the "67" Cougar's automatic transmission flywheel and bellhousing, it is necessary to add additional "balancing weight" to the 302 wedge flywheel, a "balancing weight" increase, that is by... "chance"??... equal to the stock 302 wedge's balancing weight, resulting in a balancing-weight "total" that is approximately a "doubling" of the stock 302 wedge's "balancing weight", but is exactly what is needed to "balance" the H.O. motor, when the H.O. dampener is retained.
I am running a 302 HO engine in my "67" automatic Cougar, and, by re-drilling the 302 wedge's "V" belt pulley from a 3 bolt pattern to a 4 bolt pattern (plus totally removing the 302 wedge pulley's "centering" hub-flange and then "pinning" it in/ for "position'), allows all the 302 wedge V-pulleys to be installed and thus retaining the 302 wedge's "V" belt configuration. I am currently running this set-up with "tens of thousands" of miles on it.
Delima:
I wish to install a 302 HO into a "68" Cougar, but retain the "68" top loader 4-speed and I will find it impossible to "change" the "balance weight" of the stock "cast iron" 302 wedge 4-speed flywheel (to accomadate a 302HO engine's needs) and as I do not wish to have to change the bellhousing of the 302 wedge to accomadate the "larger in diameter" 302 HO manual transmission's flywheel (because, if I do, I will not be able to run the top-loader 4-speed transmission), I need to find a way to run a 302 HO engine in a "68" Cougar in place of the stock 302 wedge engine, while retaining the top-loader 4-speed transmission and it's 302 wedge "cast iron" flywheel and it's 302 wedge bellhousing. Whatever "type" of harmonic dampner used with this combination is acceptable, so long as it "functions" with this combo.
Does anyone know of a solution to this?
