Hmmmm....I'm stuck on what to do next.

I'm thinking about doing something with the engine, but I don't know what. I have a 1980 4 bolt main 350 that's completely stock. It has stock heads, and doesn't have much horsepower. To make matters worse it has a 1969 327 2bbl intake manifold and Rochester 2bbl carburetor (with choke pull-off) off of a Camero, El Camino, or whatever, and I've been fighting it since I bought the truck to keep it in tune. Plus, it has what look like the original exhaust manifolds off the original 1969 350 that used to be in the truck, and they've taken some abuse. I'd rather pull them out before they become a problem.

SO....this is what I'm thinking in terms of bolt-ons:

1. Hooker Competition Headers. My exhaust is 2 1/2" from before the mufflers back (straight out the back). I'm thinking 1 5/8" to 2 1/2" collectors would be perfect. The exhaust pipes would be replaced from the collectors to the mufflers.

2. Edelbrock Performer Intake Manifold (non EGR). A basic dual plane one (2101) that'll take a square bore carburetor. Should I go with a performer RPM (7101)???

3. Edelbrock Performer 600 CFM Square Bore Carburetor (Electric choke - 1406). I know a lot of you have had mixed results with this carburetor, but I'm stepping UP to something basic, so I'm willing to try it. How does the choke setup in a '69 convert to an electric choke?

What do you all think?
