How do you want to obtain your 500hp? If you want to do it NA its going to take a KILLER combo, but given enough RPM it is within the relm of possibility. I'd immediately start thinking of a dart based shortblock, all internally balanced and lightened internals, solid roller cam, as high of compression as you could run, monster heads that flow like a hurricane, an intake like a spyder r trick flow R box that's been ported, etc. and rev it to the moon.
If you want to do it for less money and more than likely less headaches I'd just just build a relatively mild setup and put a blower on it. It could be amazingly tame, yet put down the numbers you seek. Either way, you should highly concider an aftermarket block if you want to approach the 500hp range. It can be done on the stocker, but its a guessing game as to how long it'll last. Some steps to help it live would be to keep the rpm's low and not beat the snot out of it at every light. If you do go with an aftermarket block, theres very little reason NOT to go with a 364ci setup utilizing a 4.125" bore. Plan on spending at least $5000 on the shortblock itself though.

NA 500hp 347 is a little tricky for the street, you need big compression or to spin it to the moon, so the safe way is to build a super strong engine and spray it a little or boost it, the choice is up to you and your check book... I can build a low10s small block easy, but it will not like pump gas to much or street driving...

i thought you had a 408 already?
i got two 351W roller's ones complete running still in the ride, and i do got a 351 at the machine shop i got bored
i dont feel like messing with the exhaust and all that crap by putting a 351w in it
Man, if you want cheap reliable horsepower your a fool not to go with a 351 based engine.. NOTHING is easier/cheaper to make power with than starting with more Cubic Inches.. Heck, even putting in a BONE STOCK 351w is more cubes than if you bore stroke a 302 to a 347.. Think of it this way, the cheap way to build a 347 would be a cast crank, sportsman type rods (not much better than stock, probably would not handle any more horsepower than stock 351w rods with good bolts and fully floated) etc.. So, but putting in a bone stock 351w, youd have basically the same "quality" parts, and still have more cubes with only a very few pounds more weight. So if you were going to invest the same amount of money into a 351w based engine, you could have a 393 or 408 for the same money and definitely have more power potential and a stronger overall combo. If a guy is building something from scratch, I dont see why anyone would build a 302 based engine UNLESS they wanted to run in some type of class with rules that only allow that. Even if you have a premium 302 intake, sell it and buy a 351 one.. Its like a no brainer to me???
i just want a 10second street car, dont matter if i gotta go 429/460.. if it dont cost to much and will work ill do it..lol
Whats killing me if my budget right now...i got $4,000 to just blow on the car, and i gotta hide my tax retunr when it gets in for the car which will be $800-$1000..... but i bought a house the paper work n stuffs goign through, i gotta get my motor built and everything before my old lady finds out how much im spending on this stuff...loll
Ok, cheapest, easiest way is something like my last Combo..Originally Posted by Inkdcountryboy
*Stock 351w block (get an early one, 70 - 74 are the best, THERE IS a difference, but even the later ones will work, just wont take as much abuse).
*CHP 408 Streetfighter kit (I would spend the extra little bit of money and get the dominator kit with the better crank and rods though)
*Your pick of heads (or you might already have a set?) I would go with AFR's for out of the box flow potential..
*Good roller cam setup (hyd or solid, I like solids but they are ALLOT more upkeep and work)
*Victor or Super Victor intake (I like the Spyder if your going Fuel Injected)
Easy RELIABLE (considering its a cheaper route) 10 second combo... You want 9's throw a little juice on it (NOS)
If you cant afford it all at once, build the lower end up, put it in with some ported stock 351w heads and buy better heads down the road...
How much to run that setup???
Ok, you got 5k
Stock block with all necessary machine work = $700
408 streetfighter kit = $1100 (or less)
AFR 205's = $1700 (or less)
Super Victor Jr = $300 (or less)
GOOD cam setup with everything = $700 (or less)
that leaves you $500 for anything you dont have that you might need (headers, swap oil pan, etc)
BUT all joking aside, I bet you can get better deals on most if not all this stuff so you can do it, have a GOOD combo, and be under your $5k easy..
We have a stock block 408 (just like I said above) in my brothers car (95 mustang GT), and ran a 11.1 at 130 mph last fall Spinning BAD (easily a mid 10 second MPH if we get it to hook up and not spin) with no power adder and a single holley carb on street legal tires through the mufflers..
Heck, do that same combo with used heads (you can get a GOOD set of used heads for $1000) and you save $700 plus right there!
I bet you could build a 10 second RELIABLE 351w based setup for $3500 pretty easy if you took a little time and did a little shopping around for parts.
Sounds good, but i rarely find good deals on stuff, i end up paying topdollar for stuff, the heads different peoples telling me different stuff between AFR 2.05's and trick flow high ports and edelbrock victor jr's...im like lost in the dark with this stuff, like would i be better off taking the drive to summit making a list and just one stop shop it or ? no clue dude
Scott,
Will's car traped at 130 mph??

11.1 @ 132 was his best so far (out of 3 times taking it down). We are hoping with the suspension changes and the switch over to Auto that we can get it to hook this year and see what it will really do
That sounds like one wicked '95! I'd love to see that car!!!

We just put a C4 in it to try to get it to work better. I cant wait till we get it to hook up once!
