With this car i would go for 300-350 ft tq. Hp is not going to matter much and may even slow the car down if the cam is to peaky. I got my 4000 pound 71 gp from a guy that had tried 10 cams and finally went with a smaller pmd cam factory cam. That made the car run the fastest at the track. The op can save himself the issues of replacing several cams to find something that works he could just get the performer or the torker. Edelbrock provides thecombos that work for little money and big results that act as expected.

The 59 wagon has to be every bit of 5000 lbs. Does it have an X frame? Might want to be easy on it with older frame. 400hp and the tq that comes with it is a lot of pressure to put on the old style frame. It will be fine with street tires and normal fun run type of driving. Some slicks and some abuse at the race track could lead to some major issues. Best to let it spin if you get a lot more power than stock. Especially if it has stock suspension and brakes.
This car will NEVER see slicks.
It's in the parking lot here at work right now. It's my daily driver, I just want it to be fun. If it doesn't have 400hp... that's OK, I just had to make a target somewhere. I want it to run good, be a hotrod. The current setup has all the parts listed in my first post in a 350 with a very mild cam...it needs more oomph....

Motochris,
You never said if the vortecs were modified from stock to allow more than 0.450" valve lift.
If they have you may want to consider the Comp Cams 270HR. Using their Camquest software configured for your combination it indicated 404 HP and 463ftlbs of torque, 218*@0.050" lift single pattern cam, 0.500" valve lift with 1.5:1 rockers. Should work good with your torque convertor.JMO
You may want to upgrade your valve springs for insurance.JMO

Motochris,

If they have you may want to consider a Comp Cams 270HR roller cam with 218* duration @0.050" lift single pattern, w/.500" valve lift w/1.5:1 ratio rockers. Using Comp's Camquest software with your engine specs it indicates 404HP, and 463ftlbs of torque. You can get a few more rpm with the XR270HR to get 411HP and the same 463ftlbs with a slight loss of torque off idle.
Both should work good with your torque converter IMO. You may want to upgrade your valve springs.
FWIW,

Thanks. I was looking at that exact cam (270HR) too. My heads are NOT currently setup for the higher lift, but I'm leaning that way. May as well do it while it's apart.

The most expensive words in hot rodding are "might as well"
