"...can these motors be stroker motors like the chevy's? what goes in what if so and do people do it? I see alot of 461, or is that just a bored out 455?..."
You can use a 400 block, then install a 4", 4.21", 4.25", 4.50"(and others) stroke crank and build anything from around 428 to 500 or so cubic inches. The 4.25"stroker is probably the most popular. The cheapest balanced stroker assembly I'm aware of is the cast crank Butler assembly, with 5140 Eagle rods, & Mahle pistons.
There are lots of upgrades available, such as forged cranks, H-beam rods, and Ross pistons.
"...motor I will squeeze as hard as I can, luckily it's a light car, geared low, and that will school most of the "fast and furious" crowd in the eighth mile I'm willing to Run 'em..."
Well, if you are gonna run the 1/8 mile, with 4.10 gears, you'll need some real sticky slicks, and some good traction bars, like maybe the Cal-Tracs. We did it with slappers, but ran 13" slicks. And if you build a stroker, it would be a good idea to go with a forged crank. You can go with either the 4.21 stroke with 6.625" Pontiac rods, or the 4.25" stroke, with 6.8" BBC rods. Not much difference in power.
"...I'll make it as radical as I can afford..."
A cast crank stroker shortblock, less cam, will cost about $3500 + shipping. Add a few hundred for forged crank.
Then add at least a thousand bucks for some well built unported 6x heads, and a decent HFT cam & lifters, and it'll run you at least $5000. And most builders will charge MUCH more than that. Don't know how much you can spend on the engine. But, this should give you a ruff idea of engine cost.
