383 budget build- questions, questions, questions

I tried to do as much research as possible, but I'm still left in the dark as to a few little things before I go buying the remaining parts I need for my build. First off, here's what I have so far:

Scat 3.75 crank
Scat 5.7 rods
Claimer Flat tops
Melling HV pump
Dart 200cc Iron Eagles; 2.02/1.6 valves.
All accessories needed
I'm going to buy a modified/painted LT1 intake from millican with the fuel rails and all. As I understand that doesn't come with the Tstat but thats not a problem now.

A couple things are mismatched, but it is mostly because of the deals I found on part prices. I just need an engine to put in the car because right now its not drivable, and I'm only 17 making like 150 a paycheck so I can't really afford to sacrifice much money. If anyone could answer any of these questions I'd appreciate it.

On to the concerns-
1. First, and most important as of now- The cam I got with the kit is a hydraulic flat. 224/234@.050" .465/.488 with 1.5 rockers. I plugged these numbers into Desktop Dyno and got a decent number..460hp@6000. This isn't really what I'm looking for though. I want the power peak at about 5500, with loads of low end torque. This one makes around 370 ft/lb@2000.
I'm looking for another cam, and the best one about now seems to be a Crane Energizer; 1000052..120 bucks, 216/216@0.50, .454/.454 w/1.5s. This one gives me 440hp@5500, with more than 400 ft/lb low end at about 2000. (I know these numbers are very optimistic, but I figure the bigger the DD, the bigger in real life.) This is what I'm really looking for, but I'm wondering if anyone has any other suggestions? The duration seems really small, but with any bigger duration numbers DD2000 says it starts to look pretty bad. I need opinions here.


2. With the flat tops and 64cc heads, even with a .060+ (I believe..cant remember. the thickest I could find) head gasket the compression is up to 11:1. This doesn't really seem practical for the situation, but I've been reading that I could have my calculations wrong. As far as I know, the block has never been decked before, but I don't know what the clearance is until I begin the buildup of the rotating assembly this weekend. Am I missing something here? I don't want to be knocking on 91 octane. I'm going to polish the combustion chambers, maybe that'll help a little, but I need other options.

3. The LT1 intake requires a small HEI distributor from 87+, but as my car is an 85 I don't have that. My idea of HEI and remote coil is still a little foggy- If I were to buy an 87+ distributor and an aftermarket coil, would it hook up easily to the other car's stock components? If not, what else would need to be replaced?

4. I heard that I should be looking for SVO injectors, but I'm not sure what poundage I should be looking for to fit the needs of the engine...Well.... ...?

5. Chip. The 383 isn't going to like the 305's brain. What's the best place to go to? I saw that Millican makes em. Any good? (No, I don't have enough money to do my own. Not now anyway.)

I think theres more but this is all for now. I know its a lot but I don't want to become another horror story.

Anyway, thanks for any help you can give, guys.
