347

[Inkdcountryboy]

What would be the best way to go with a 347, id like to make atleast 500hp, but yet still find the best deal on the things to do it, im looking for a bang for my buck, any help ???

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?

[Inkdcountryboy]

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

[Inkdcountryboy]

i dont feel like messing with the exhaust and all that crap by putting a 351w in it

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.

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
