I bought a 81 Trans Am with what I believe to be a '76 400 , XA code block
Whoever put this engine in this car (originally a 301 Turbo WS6 euro-export car) modded the engine before it went in.
I don't know if they only did some bolt-ons or if they went deeper into the engine, like overbore and so on.
Heads are 6X-8's (orginal to the engine) don't know if the've been worked - think stock
Intake is a Edelbrock Torquer II
Carb is a 3310-3 Holley 750 vac.secondarys
Headers of unknown make
Roller rockers
Cam is unknown, probably not stock
The T/A has it's orginal 3.08 Posi with discbrakes

The T/A runs okay, but the header gaskets leak so I need to take them out before I car really drive it.
It idles okay not really choppy or anything.
Anyway, with the 3.08 rear it does about 2.500 rpm on the freeway.
Acceleration is nothing to write home about, although I must say I haven't pushed it very much into the higher RPM range. I kept it below 3.000 rpm.

From what I know the Torquer II has a range from 2500-5500 rpm (!?!)
And I think the Holley 3310 is also a little too big. (plugs are pretty wet)

I just want to have a spicy cruiser, not a race car. So I want as much low end torque I can get. I'm not interested in high rpm horsepower.

I was thinking of putting on a stock '73-'76 4bbl egr intake (I've got 2, that's why) with an Edelbrock 600 cfm carb 1405 (smaller I know, but european fuel prices are way worse than stateside), and putting in a new timing chain, a new Summit 2801 cam, and leaving my roller rockers as they are.
I already got all these parts so that's why I'd like to do this.

Is this a good plan?, anybody got experiience with a similar combo?
