The best one IMO is the Summit Racing K6401 Install it around 104 and you will be happy camper and ...it is cheap as dirt
I have used about 50 of them over the years--perfect entry level TQ cam that will giddy up nicely --sounds decent and makes a tire melter out of a low compression 440 --anything else in that application is lots more $$$$$ and IMO not any better
In that wagon maybe even go 103 on install CL Thing is you have everything in place for a hot 440 EXCEPT compression so it is the limiting factor--so shave heads about -040 or swap to the 6401 cam installed like mentioned
a 3/4 ton car is hard to get moving
