The 041 is fairly high strung in a 400 and would only be slightly less so in a 428. Big hole in the low-end torque offset by high rpm top end charge. In a 455 it’s more drivable. Rhodes lifters improve the low-end torque by shortening the cam duration but a 2,000-rpm stall speed Convertor intended for a big heavy RV’ is not optimal. I have a Hughes GM25 converter with a “RA4-ish spec cam (Crane HIT 284281 in a 455 w 3.55 gears. The converter is a good match to the cam. Yours would benefit from a similar converter stall speed.

I must ask " How does the Gear vendors, that is installed in my Vehicle, offset things, help/hurt etc"...?
I also want to say that the Vehicle came with the # 866 Cam, I think that is the # and it is the 1956 Tri-power one that I loved. Going to this 041 Cam is new, for when I put it in this Vehicle, shortly after I destroyed the Trans. I have yet to get used to this 041 Cam yet. With the passing gear and downshift system now working, the passing systems working again, seems to make this new Cam more enjoyable. It is not bad; I will let you know after I put the motor together and test and tune for a while.
