is a holley 4165 6120 a bad choice

[coggonobrien]

i picked up a used holley 4165 6120 for $50 to replace the original 4 barrel on my 69 blazer. motor is a 355 with a weiand intake. is this a bad choice in carb? my buddy seems convinced it is strictly high performance and will never be streetable even though all the material i've read says its a bolt on replacement.

also if anybody has any literature on tear down/tune i would appreciate it.

Thanks,
David
