Hello all. I'm trying to help out my brother with his '51 rat rod Chevy pickup. He put in a Chevy small block 350 (3970010). He's looking for a cam with a nice lobe but still realistic on the roads. From what i have researched online and magazines i need alot of info to figure out what cam is right for me. Here is what i was able to grasp.

Engine is a sbc 350 v8 block 3970010
Heads are 3998920 1.94 In 1.5 Ex 76cc
I believe 8:1 compression
edelbrock 4 barrel carb 600cfm
4 bolt main
intake 340261

He's looking for low to mid range rpm cam with a nice lope while keeping the cost down. Now i have stumbled across a site were they installed a comp cam hydraulic roller xr276hr, 180cc rhs heads and 1.6:1 pro mag rockers. Sounds nice although the price is out of my range. He would like to keep this install under a $1000. Can any engine enthusiasts shed some knowledge and help me figure out what exactly i need. Thanks
