i found a place to buy o.e.r

rob from rotary shack sell's the mani for around 200$ i think.

The main thing for Edelbrocks is to space it up high enough to clear the water pump housing. After that, it's just a matter of tuning, IIRC.

what would i have to do to the o.e.r to make it run right on my car. what size would be good ect.

I'd get the 47mm. Making it run right is a matter of tuning.

yeah figured that much. i was told with a 2-barrel its harder to tune for street is this true.

To some extent. There's a lot more you can do to tune them, so there's more to screw up, and they're usually not set very close to how we need them at the factory. Expect to buy at least one set of everything, and probably a couple sets of jets and air correctors before you get it right. Invest in a decent fuel pressure gauge and a narrowband at the very least, wideband of course being preferable.
