I believe it can but I would like some other opinions.
Right now I have the BBK Shorties which I am looking for a long tube replacement for.
This is the cam I am looking at:
http://www.ws6project.com/user_stor/...oducts_id=1445
Or a GM846 I found used on another forum.
Which would you say would go best with this setup:
GMPP LT4 Upgrade
--Cam
--Full Roller Rockers
--Valve Springs
--Retainers
--Protech Gaskets and Seals
--Chevette Bearings all around
--Chevette Rocker Arm Studs
--Chevette Piston Rings (Chrome moly (SP?)
--Comp Cam Hyd Roller Lifter
--Porting Work
GMPP LT4 Intake Manifold
--Porting Work
Gasket Matched Intake Manifold, Cylinder Heads and intake and exhaust manifold.
BBK Short Tube Headers
Flowmaster Exhaust
Thanks

The LT4/GMPP rockers, if they are what you have, are limited to .550 lift, the cam you posted is over that with 1.6s.
The 846 cam is also over that with 1.6s. So you are going to have a hard time finding a cam or you need to buy different rockers, if those are what you have.
I would have skipped the LT4 package entirely and spent LESS on better performing parts, guess it is too late for that though.
"gasket matching" is not necessarily a good thing either.
"comp hydraulic roller lifters" are almost certainly exactly stock with a little extra pricetag.
No idea what all the chevette crap is all about.
The LT4 springs are not capable of controlling any worthwhile cam.

I did not build it but thanks for the opinion. I bought the car and this was some of the list of parts i was given.
I did get some useful information out of that though. The rebuild was done over a year ago.
