It's not on the road yet, we only recently fired it up on the bare chassis and it has some very nice crackle and snap to it. The L-82 cam with it's longer duration is more suited for the longer stroke of the 350 while the "151" has a few degrees less duration for the shorter stroke 327. I also advanced it 4 degrees for some more bottom end.

Good luck and thanks.

Personally I would just use the L-82 cam and install it 2 degrees advanced. My 041's have all the holes drilled for accessories so I would think there is plenty of material there on yours.

Why? The stock cam will wimp out on you. Spend another 100 bucks and get some decent lift to take advantage of the heads. Airflow doesnt matter if your valves will not lift enough to take advantage of it.

Why, because it is dead on reliable with no wear issues associated with the higher, faster ramp rates of some of these aftermarket pieces and can make 350 HP+ at the crank. Agreed you could make a few more ponies with something else but at a cost.
IMHO, 224*/224*, vl .450”/.460”, icl 114*, ecl 114*, LSA 114 are not bad numbers for a basic warmed over 350. Another .020"-.030" of lift doesn't buy you a whole lot more for a street car.

It would seem that if I was unhappy, I could always use 1.6 rockers, that would give me .480/.491 valve lift.
I'vr heard bad stories about people not breaking in the high ramp cams and then wiping a lobe at 2000 miles or something. I don't want that kind of trouble.
