NA doesn't mean Nitrous Assisted? Dammit I screw everything up. :BangHead:

My build and a 100 shot equals 400 and it's really fun. I'm doing a stroker this winter. :thumbsup:

Well I definitely care about drivability... I didn't think I'd have to sacrifice too much to get there. I have about 5k to put into the car right now... but that is just the initial. I would prefer to be conservative with my money, not just throw a couple g's down then decide to go with different settings and just replace it.

I guess I'll have to look further into everything, and maybe get some test rides. I was thinking with 400N/A I could make 500 with a blower and not have to crazy of a ride but with awesome power.

 

[Lee12609]

N/a and blower builds take very different needs, sounds like you need to do a lot of research before spending a dime.

 

[got5.0]

I'd boost it....

You can make 500 with a 302/306 H/C/I setup and a blower dude.

X2, easily, just cost money.

 

[MustangMoser]

I'd boost, but if you're going N/A, 400 rwhp is getting close to the limits on the stock block. I'd go 351W based.

 

[5.slower]

Save your money and spend 1400 with shipping on a boost brothers turbo kit. Easy 400rwhp.

 

[Slinger]

put a small block chibby in it,duh......no just kidding,the 347 is your best option.it leaves room for more improvent later,like a sc

 

[97 king cobra]

Simple h/c/i on your stock 302 block will make 300-330rwhp...(depends on good of parts you get) add a blower or turbo and u will be at the limit of your block. 450-500rwhp.....

If ur goal is 400/500 hp that is the best route to take. No need to spend the extra money on a stroker kit for a stock block.

Now if u had an iron eagle dart block, sure get a 363 stroker kit, 9 to 1 compression and a nice turbo but your talking an extra 4k and double the amount of power your looking for.

 

[summer_runner]

OK, so whatever I end up doing I will do I will be doing to a 302 not in my car right now and then just swapping. Do you guys know what kind of HP at the wheels I would be looking at if I did a 347 stroker then a mild to medium H/C/I?

Just wondering what it would be since a 302 would put me somewhere around 300-330rwhp...

 

[ttocs]

400 hp and $3k budget.....

Don't forget that you are prettymuch doubling the stock power and the tranny will need some upgrading sooner then later if you push those numbers.

400 is my longterm goal for when I get my turbo but I am planning on it costing more then $3k now, and I already have suporting mods done and heads waiting.

 

[Jrgunn5150]

Let's say for arguements sake (some are higher, some lower) your normal H/C/I 302 makes about 300 to the wheels, so just extrapolating from that...

300/302 we'll round... 1 rwhp per cubic inch... So, a 347 would make right around 347... One of the mag's just did a 351w in a Fox with nice heads, a nice intake, and a mild cam that made 310 to the tires... You don't just call Trickflow up stage it up and get 400 rwhp

 

[M1Tanker]

347, big heads, big intake, big headers. A guy on my local board is making 400+ whp on a 347 that NXCoupe tuned, and he's picking up 24 mph out the back end (drag racing), which is huge for an all motor street car.

 

[ProKiller]

400 is a tough build. you can't do just a standard top end kit to reach that goal, you will either have to get large heads and intake and a cam to pull it all together or break into the bottom end.

you can get 331 without having to do huge heads and driveability issues. Here's proof of that: http://www.stangnet.com/mustang-forums/818427-331ci-9-1-compression-afr-185-comp-headed-dyno-results-inside.html


In the end, i have to say it would be cheaper and easier to just slap a blower on there and call it a day. You'd be up in the 300-350 range with just that. toss on h/c/i and your in the 400-450 range. probably do all that for less than $5k. an N/A combo will run you in the $5-6k range and still might not break 400rwhp.

 

[summer_runner]

I agree that after reading your guys posts and researching tons on my own, 400 is a tough number. 350 would be alot more reasonable with a 347 stroker kit so I think that's what I will be aiming for, then slap on a blower. That should put me where I ultimately want to be... 500HP+ hopefully.

One more question: where should I look for information on good H/C/I combo's for what I want, or any suggestions?

This is where I wanna be but with a 347 I'm thinking now. I will just have to get the car to be able to support it now.

 

[Jrgunn5150]

If you really wanna learn alot about how to make power and how engines work in general go to sbftech.com. They aren't a nice crowd over there though, keep your head down and listen, after you get I think 10 posts they have an excellent tech library.

 

[ttocs]

since the new v6 and gt numbers went up like they did I have been considering some kind of forced induction for a longterm goal....

 

[summer_runner]

400 N/A...no problem


I'd do a 347. If your block is in good shape and you can deal with the downtime, buy a kit and have a machine shop do the work. Otherwise, if you can't have the car down for a while, get the shortblock.

Don't be afraid of compression, run 10.5-11:1.

Stock block
CHP 347 kit 5.315 long rod/3.400 stroke and a good forged piston.
Long tube BBK 1 3/4" headers
Edelbrock Victor 5.0 or a Victor Jr EFI (carb style) style with a 90 degree elbow
AFR 205cc heads
Custom cam (I like Ed Curtis @ Flowtechinduction.com)
36lb or 42lb injectors
75mm throttle body minimum


Done.

What would the driveability be on a setup like this? My guess is that it depends alot on the custom cam but would it be kinda rough in idle-low rpms?
