There's no reason to eliminate the torque arm. It's a very good design, and provided you have an aftermarket one - you'll be more than ready to plant power to the ground.
2500 is low for a strip car with a SBC and will leave you disappointed. I'd suggest no less than a 3000 if you're trying to make good numbers. The better converter you get (more $), the more they feel like stock and have better driving characteristics while offering more power without as much parasitic loss. I wouldn't even think about a converter until you get a large transmission cooler, or you'll find that a new transmission is something you'll be buying very soon.
Those heads are decent, but there are better out there for the dollar spent. If you're going to bother getting roller tip rockers, you should definitely spend the money on a good set of full fulcrum roller rockers.
High volume oil pump isn't needed.
I typically don't like shelf cams, and if you're buying a new roller cam it's pretty dumb if you go that route since a custom grind is exactly the same price. Call someone who knows their way around camshaft profiles and not some random cam salesman.. Mike Jones, Bullet Racing Cams, Chris Straub, etc...
If you decide to buy a carb, then I'd get mechanical secondaries for responsiveness. I'd also argue getting a 750 carb depending on how much power you're wanting to push.
Also going to need to address your fuel demand issue.. new fuel pump + regulator is in order.
The rest is up to you to do research, phone calls, etc. Slapped together parts = slapped together performance.

Re: 355 build in 86 berlinetta
thanks alot. plan on running an aluminum radiator and a new tranny cooler but nothing too big. building a th350 to take 500 hp and tqu. stock rockers dont bother me but did some research and was told they can free up some horses and lengthen the life of valve guides. stock oil pump doesnt bother me i guess, i have seen them do 90 psi all day no troubles. read that stock torque arms are weak and can crack tranny housing. after market ones arent that cheap and then i would get a diferent cross member.
