300-325HP
With that camshaft you're gonna need BIG compression to get the most out of that engine. You won't have 9:1 CR...even if its zero decked.
Compression is power. Get those heads milled or bigger pistons.

Good to know! Thanks! Do you have any recommendations for high compression pistons. Also what ratio do you think i should shoot for?

I'd say the bigger issue is the cam is huge relative to the intake and heads. The intake will be more of a restriction than the heads. Honestly, I'd just put a milder cam in it - it will probably run faster. The Lunati 51014 would be a great match to that setup.

If I was you, I'd take it to the track and run it so you have a baseline. Practically any reasonable change you make will show a significant improvement, and a bad day at the track beats a good day not at the track. Or something like that.

Thanks for the input! Ok since you say the intake will be more of a restriction, do you think i should port the intake, or possibly the intake and the heads? I ordered these parts as a package so they are on their way as we speak. I am very new to this whole v8 thing, unfortunately. I was into 4cyl turbo setups before

It's the wrong intake design for that cam. On a 302 with that cam you'd want a single plane intake; but then the heads will be the restriction. What is the intended use for the car?

Well, you have a number of options. You can sell it all off and put an LS motor in it (cheap, ubiquitous and a junkyard long block can hit 400+ hp with just a cam swap), or you can work with what you've got. I'd limit the stock explorer short block to 6,500 rpm. Towards that end, for now keep the other parts, sell off the cam (it's going to be tricky to make it driveable anyway), and pick up something better suited - a split duration cam in the 220-225 intake and a bit more on the exhaust at .050. I would stay away from cams with steep lobes - hard on the valvetrain, and the performance seems no better than (if not slightly worse) than more conventional cams.

Such cams are plentiful in the classifieds. 380 hp shouldn't be too difficult to hit with your other parts. I'd bet you'd break even on the cams financially.

I disagree , the Air Gap intake makes power. Looks like a good combo but CR needs to be at least 10:1 with that cam. I'm guessing 320hp rwhp.
