Default Cam selection for 416 LS3

Just ordered a motor from LME. It is a 416 LS3. I think I went to big on the camshaft. I ordered it with a 244-250 on a 114+3. Lift is right under .650. How is this cam going to behave? Do you think it is over the top? I want something farely aggressive. I only drive the car on Sundays. I have a 3600 stall and 3:73's.

My 418 has a similar cam with .625 lift, it's sorta bad about bucking at low RPM in 5th and 6th, and of course 1st, but other than that no complaints.

LME's ported CNC LS3 heads. They flow 350.

I run WCCH LS3/L92 heads on my 403. I've been through 3 cams and none anywhere near as big as you've got. My current cam is almost 15 degrees smaller than yours. Numbers in sig. Big cams on these heads is a mistake.

Just my $.02

That cam isn't to big for those cubes. With a good tune it will drive well. I wouldn't worry about it at all for a weekend toy. How it will work with those heads is a seperate issue that I would get professional advice on. If LME selected it with those heads in mind you should ask what kind of results they've had on similar combos.
