396 BB Question=Need advice

[alsriv2]

Hello everyone.

I have an interesting dilema and need some advice regarding a camshaft.

Let me give you some background first.

I have a '69 C10 longbed that came from the factory with a 396. The previous owners have done some work to the engine that was not done well. When I bought the truck the engine was in pieces in boxes in the bed. (unfinished project)
Here is what I have:

'69 C10 396 Longbed
3.73 posi rear
Hughes performance TH400 with 2500 stall converter
Original 396 engine block
'71 402 heads (better flow) (Changed by P.O.)
Hooker headers/2.5" exhaust/x pipe dumping out in front of the rear wheels

I selected a performance machine shop in my area that has a fantastic reputation, the engine has been completely overhauled and they have done outstanding work. I am very pleased with their work.
Work done:
Forged crank - balanced
Line bored block
Probe forged pistons - 10.1 compression/rods line bored and balanced
Cyl bored .060 over
Heads completely overhauled with new stainless valves
New springs and valve guides
1.7 ratio roller rockers
Rotating assembly completely balanced

I left the cam selection to them as I do not know much about cams and there are too many choices for me to pick thru. I had thought a good hyd flat tappet cam is what I wanted, but decided to upgrade to a roller cam due to the possible issues with modern oils.

Here is what they installed:
New Lunati Hyd roller cam (Part Number: 50249LUN)

Cam specs:
(From manufacturer) Hydraulic, rough idle. Good cam for bracket racing in 454 cubic inch motors. Needs 3500 RPM stall converter, headers, 10:1 compression ratio or better and 4.10 gearing. Works well with nitrous!

Advertised Duration (Int/Exh): 290/300
Duration @ .050 (Int/Exh): 232/242
Gross Valve Lift (Int/Exh): .578/.595
LSA/ICL: 112/110
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: 3600-6600

Here is my question. In the pre-build discussions with the machine shop, I described that I wanted a strong and reliable build with great low to midrange power and that the truck would be used on weekends and occasionally taken on the highway for vacation. This truck would never be raced or see a track.

I am concerned the cam they selected is too radical for what I want to use the truck for and I have the opportunity to have them change the cam before it goes to break in and dyno. After it goes thru the dyno process, the replacement costs come out of my pocket.

Any thoughts or suggetions would be very much appreciated.

Take care.
