But forgot to mention, if it can be done for 5-$6000 like some are saying then thats great, put the extra money into beefing up the tranny. Also is the stock axle going to be good enough for this or do i need to toss that?

if you are doing an aftermarket block you might be able to do the bottom end for 4,000 including the block.

Here's what I'd do. ...........


Get a built 306 short block from Fordstrokers.com and
request it be made on an "early vintage" or "mexican" block.
They are strongest of the "stock" blocks. Will run you about $2,000.

Get a custom head/cam package from camshaftinnovations.com
run you about $2,000

Tell both those guys what you're doing and they will get you the right set-up.

Then get a turbo kit from Quicktime for about $3,000

Another $1-2,000 on stuff like Holley Sys II intake and injectors, MAF, ect.

You will easily meet your goals and have a rock solid power pack.

if you're spending that kind of money on a block then why not get a dart or world block? and as for induction, i'd go a single turbo route

[e3sean]

if u have 8k to put into a motor now go and get the boss,dart or manowar block then you can do a high reving turbo 347 stroker.
you will proly be well over your 500 hp goal but u can decrese the boost and timing.

Because a Dart block would more than double the price I just listed ...........

If he goes with a Dart 347 running a turbo he will be making 600-800rwhp. ....... overkill for what he wants

As long as your current block is not cracked (unlikely) it will be no weaker or stronger than a new factory block. Either way you will need machine work so you aren't saving any money there either. People use old blocks all the time. After you have it machined the cylinders and mains are new again anyway.

Some metallugists make the argument that the metal in seasoned blocks is actually stronger than a brand new block due to repeated heat cycling relaxing the metal. The metal in fresh castings is actually slightly more prone to cracking (this doesn't apply to billet or forgings). I doubt there is a significant difference in the strength, but for sure I wouldn't worry about using a seasoned block. If you plan on making 500 hp and are starting from scratch, I'd consider doing a 351w stock rebuild.

I've heard that before but I don't know anything about metalurgy to know if there is any fact there. Sounds like a good theory though.

i agree on the 351 you wouldnt even need boost to be 500+hp to the wheels. i always have alot more respect for cars making big numbers of hp and low 1/4 mile times with n/a. and it will be alot easier to tune. then u could put the rest of your money on your chassie stiffining and suspension maybe even some nice paint

[ryans88gt]

^ + fast NA cars make super fast FI cars

[_UnLiMiTeD_]

my goal of 500hp was because im not sure on how far one can go for steetable and pump gas.

If i can hit 650-700hp and still be streetable and use pump gas then sure! lol. I just want sure what i could get for an $8000 price limit and still be realistic.


So i have a few options by the sound of it, but still a few unanwsered questions.

Options so far is a 306 mexican block, custom heads and cam with a single turbo kit
Or a 347 dart block with a turbo
or a 351w n/a setup

Now my questions. Tranny, will a beefed up T-5 be sufficient?

Also the stock axle, can it handle this type of horsepower? Im not looking for a car to do wheelies down the track, but in order to make a decent pass down the track with a car making this horsepower, im going to need a good pair of drag radials which means i will need an axle to hold it together. Can the stock Axles handle this kind of power with drag radials?


I appreciate all the help so far guys, i find it much easier to have an idea of what to get before i have the car.


The color im torn between a deep red pearl or a deep blue pearl. I was at mission raceway watching the races the other day and seen a car with a really deep red that almost looked black from far away until the sun hit it and it was almost like a candy apple/laser red. Paint will come first so i dont have a half ass looking paint job with a different color engine bay compared to the rest of the car, get it painted with the car gutted.

[built351w]

Well another option is use a 351w block. They have beefier mains and thicker webbing. People say they hold up to 600hp with issues. In order to run a 351 you need a different oil pan and headers. A 351w also has a different intake manifold, oil pump, distibuter and obviously internals. Basically the deck height of the cylinders is a little taller that a 302 block.

I think this is the way to go cause it's WAY cheaper than getting an aftermarket block

you'll need a tremec transmission

[_UnLiMiTeD_]

yea i had 351 as an option. Im almost leaning towards a turbo setup mainly because then i have that room to go higher with hp later on if i decide to. I dont know, theres some real nice options to play with its so hard to decide what i want.

still no anwser about using the stock axle though

you said 2000 for a block right?

Dart: Ford Iron Eagle Sportsman Blocks

or

Dart: Ford Iron Eagle Blocks


not to be an asshole but they both look less than 4000 to me (including finishing work)

but on a side note, if you willing to go with a 351w then i'll change my vote to that

[e3sean]

if u stay with the 302 based block a beefed up t-5 will hold it but the torque of a 351 will need a stronger tranny. also the stock axels should be fine just get a good set of gears. if it aint broke dont fix it.

[e3sean]

i think a 408 stroker with some AFR 225's an edelbrock efi spyder intake and a tremic transmission. 10.5:1 compression and some 91-93 octaine coustom grind cam and you will have one hell of a car.

[_UnLiMiTeD_]

so no power adders then? lol

I should start a poll with all the motor choices you guys have given me and see which one wins

351w N/A
408 Stroker N/A
306 S/C or Turbo
347 Turbo or N/A

Remember with all these motor choices i still want A/c, power steering and pump gas.


Also if you can hit over 600hp on pump gas why do some use race gas at these horsepower levels?

[83fox]

408 ftw

Because its easier. Alot of people would rather tune for the most power on race fuel than to try to tune high power levels that run safely on pump gas. Some tuners don't know how either.

[_UnLiMiTeD_]

Well gas is already high enough so i dont find it worth it go use race gas when i know it can done on pump gas anyways.

I love all the motor options but hate them at the same time because they all sound awesome. N/A maybe harder to tune to hit 500+hp on pump gas dont you think? Or am i way off on that
