It was a real runner with no "low end bog" and did well on Grudge nite at the strip (no time slips for grudge runs). Hence I find it perplexing when I hear guys here with 400-455 engines real concerned about a cam with more than 210* @ .050 when I ran a "big" cam in an engine with 50-100 fewer cubic inches. I find myself agreeing with Formulajones on this topic. The 041 has really mild .050 figures and arguably the advertised duration is rather lengthy compared to the aftermarket cams which could give a rougher idle than my 284H cam.

I'm actually looking at the Voodoo 704 cam for my 428 as I already have my HiLift Johnson lifters (HFT) in place for my cam swap. Still the 041 is tempting as it is a Pontiac cam and I can price it much better than the Voodoo. Thought I would throw this thread out for thoughts on it. Thanks all.

I like the 041 in a 428, as long as it's no less than 10:1 compression, it'll run fantastic. I'm certain Cliff has done that combo a few times.

I did a 224 @ .050 cam in a 428 with a 114 LSA, with High Lift Johnson standard lifters and 9.7:1 compression and it's baby smooth, excellent vacuum and snappy throttle. My feeling is that it's really too small of a camshaft even for the 428.
