Edelbrock Rpm heads on 360

My old a833 isnt a fast gearchanger that’s for sure. Nothing broke so was a real good day out
But, that A-833 can be modded to shift like greased lightning to at least 7200(the highest I go to), or you can buy pre-prepped gears and sleeves from Brewers.. However;
At your rpm you shouldn't be having a problem, and the mods aren't really required. Perhaps just a lil more departure and or a thinner oil. Some guys have had success with synthetics, but I did not, no matter how many mods I threw at mine. I really really tried but that oil was just too slippery.
One of the most successful mods you can do is to anchor the external levers to the studs so they absolutely cannot come loose or wiggle around. I loc-tite the cavities and the special nuts. The loc-tite turns to "stone"and that's the end of it. Make sure it doesn't wick into the cover. I have used both blue or red, but for different reasons. If the internal O-rings on the pins are new then Red, cuz once Red is used getting the levers apart will be tuff. If the O-rings are old then blue cuz little or no heat will be required. After the loc-tite has set, adjust as usual; I don't bias the gate at all cuz my car a streeter, and I still occasionally gotta downshift like lightning too,lol..
