crane cam 272 H10, .454 any good?

i am buying a cam to go with my setup. i just came across this cam in northern automotive and its an energizer cam and lifters set for 99.99. sounds like a really good deal. this is my setup so what do u think? 350 with ported 58cc heads, not completely sure of the cam but this one is 2000-5000 rpm, 272 duration, 216@.05, 110 seperation, .454 lift., edelbrock performer intake and carb, headers, and cutout. i want a cam that will atleast be a little noticable at idle but i still want low end power. so what do u think?

It will work fine for what you want but it won't produce a lopey idle.

I used the Crane 272 hmv in a 350 once.
It was the dual pattern 216/228 @050, the idle quality certainly wasn't stock, but it wasn't lopey either. The fuel economy on the hwy was about the same as stock and not quite as good in town as the stock cam. Greatly improved mid range and top end power. It was an excellent trade off for the little bit that was sacrificed on the bottom end and the slight loss in fuel efficiency.

The cam you're looking at uses the same intake lobe as the one I used and then uses that identical lobe again on the exhaust, instead of the larger exh lobe like mine had.
It's basically a single pattern version of the same cam as the one I had.
The lopier the idle is, the more you'll be sacrificing bottom end torque and fuel economy, as a rule.
It will idle like a cool street machine, not too rough, but not smooth like factory either.
Bottom end will be good enough that you could use a stock converter if you wanted to with a 350.

I have used that exact cam many times. You won't lose any noticable bottom end. Maybe a little bit below 2500 but nothing you're likely to ever miss.

Idle is just a little more noticably "choppier" than stock. It'll probably like to idle around 700-750 in gear.

It'll idle against a stock stall converter, too, but it will appreciate a 2200-2500 stall converter if you can swing it.
