Engine building kit--

I have a 350 4 bolt mains that I'm getting ready to build, it's been since the 50's that I've done this but have a friend that will help. I have the reworked heads that a guy did for me and he said he put new 300 springs in them. I'm building a 32 Ford roadster and will not be burning rubber, just want a good sounding engine. my question is I've been looking the net and the Summit and PAW catalog. it seems to me tht PAW has the best deal with their "super stock master kit"--any advice on this from you guys, will the cam in this kit give the engine that loap at idle. I have a lot to learn again at 64, I'm driving a 23 T-bucket w/ 350 and 350 tubo trans now but I didn't build it. I hate to sell it but can't have two rods, asking 15k and it can be seen www.mikegoldmancustomrods.com --thanks for any help, Richie
