"... I was leaning to the 41 cam because thats what was in that 428, yes we loved the hard lope..."

The 041 cam acts "bigger" in a 400 than in a 428. And it acts even smaller in a 455. We ran it with Rhoads lifters, in our 455 bracket engines. We ran TH400's with stock 13" converters. The engines would idle low enuff for us to launch from an 800 rpm idle. That's a lot of off/idle torque. Same cam in a 400 would produce MUCH less low rpm torque.

"...my buddy when I was young said it had a 410 rear"

But hey, if you do indeed have 4.10 gears, the 041 might work great for you.
