the 4.2L block is exactly the same. You don't need brakes etc, because it's the same weight as what you've got -there's no difference. The only difference is the stroke from the crank.
And that's why it's cheaper to simply exchange the block to increase your displacement. Everything else will bolt up. But I wouldn't recommend using your 98 heads because they're restrictive (just like the 94-8 GTs). If you're on a budget, run to the salvage yard find a cheap 4.2L in good condition they're like 300 dollars or so, pick up a 99-01 intake manifold, sell the 4.2L manifold and pick up a programmer. you'll pick up 60+ hp, 35-45 ft /bs of torque for 6-800 dollars + installation, depending on how much of the work you do yourself. You can disconnect all the fittings & electronics, have them drop the engine in, and you can take care of the rest of the installation.
Then you're a cam away from being competitive with the GTs, and you won't have to worry about the Sport Compacts.
A v8 swap requires a new computer rewiring, brakes, suspension, rear end etc. it all comes to $4000 or so + the cost of the engine.
Alright then, I'm seriously considering the 4.2 swap, thing is, I only have 25,000 miles on my 3.8. So I don't want to pick up a used 4.2 with 90,000 miles, know what I'm saying.
And yes, a website would be great :smilie, but I know a few local junkyards as well... thanks for your help
