Need some help deciding the next round of upgrades under the hood.

Since I've been pouring over parts catalogs to get all I'm going to need for spring cleaning/gasket swaps due to all my oil leaking.....I've had to look at performance parts as well and I'm wondering what to do.

In the back of my head, I have been planning a boosted 347 build. 600 horsepower at least. But given what I already have on the 302, I think that's got a lot of potential there to be a N/A beast as well. I mean, the H/C/I swap, new rockers, bigger TB, AC and Smog delete, equal length headers (already on order) with my full exhaust, and a CAI (also on order), there's some definite power potential. I'm still running a stock MAF/Injector set up, stock ignition, and stock timing though.

So my question is this: do I keep it as it is, concentrate on bolt on stuff up until I have the money to do the full swap and pull everything? Or do I start with some higher flow injectors, bigger MAF, a good tune, and a 6AL box? What kind of power potential would I have with my already done bolt on parts, lets' say 24 or 30 lb injectors, a 6AL, and some tuning by someone who knows what they're doing?

This is the first 302 I've ever worked on so I'm not sure about the power potential. But if I could hit 300 RWHP or higher, I'd be a happy man.

I appreciate any input.

What I meant by "as is" is by not adding any more parts until I have the money to do the entire swap.

I am trying to figure out upgrades for a little more power to last me until I have enough money to build a bitchin' 347. I had heard that number about stock blocks too, so maybe 600 is a bit much. I just want some serious power down the road.

Let me re-phrase my question, because I feel I didn't properly ask it:

Right now, running the TFS upper and lower intake, 70mm TB, AFR 165's, Crane 1.6 rockers, stock headers, no cats, A/C and smog delete, stock ignition, injectors, and MAF too.

I want to look at making more power (for the next few years before I have enough to build that 347) and doing some parts in the summer time. I want to know if new injectors, a new MAF, and a new ignition box are a good idea to free up some more power for the time being.

Does that make more sense?
