Cast crank is fine. It should be good for about 500 horsepower.
If you just want a fast street car, then 450whp should be more than enough to "put a smile on that face"...
Ditch the I take and cam, I personally went with an xe274hr cam, AFR185's, and a track heat intake

I am new to NewJersey and don't know of any shops or tracks. I just moved up here a few months ago. used to know a friend in FL when I used to live there that would build the motor for free cuz we were good pals.

I don't have any friends up here unlike where I have lived all of my life so I am pretty much screwed. Yup...it sucks.

again it comes down to what you want. How much HP are you looking to make really? do you have to pass emissions? are you gone to S/C or turbo it? and what is your budget? and what do you really want out of the car is it a street car or a DD or a race car or weekend street car that you want to be fast or real fast. A 12 sec car is a far cry from a 10 sec car they are not even on the same page.

Now when you say HP is everyone here talking about RWHP or crank? I am looking to have a daily driver that is just damn fast. I don't want to die from driving it improperly but I do want it to put a smile on my face whenever I drive it and put my foot down.

If the cast is good to about 500 HP again the stock block should hold up right? (also is this crank HP or at the wheels?) This car wont be a track car...just a daily driver that I can be proud to have fun with other cars on the road and the strip)

If the car being naturally aspirated can get me in this category/range, it will save me a lot on not buying the SC or aftermarket block/forged crank. Also, what kind of tranny will support this? If a factory can, I would prefer a 5speed for fun but if I will gain a significant amount of time and maintenance, I will go with an auto.

I look forward to more help with this and everyone on here so far has been more than nice. Thanks.

If this car is never going to see the track then 800 hp is pointless, youll never be able to use that Hp on the street.
not to mention you would have a really hard time planting that power to the ground

trying to get even close to that HP N/A will cost you more then if you got that horse power from a power adder.

A power adder as much as they cost will be cheaper then building it with out one


as for the stock block, there is no magic number where they will break, some may break at 450 Hp some will break at 500hp and some will make it to 600+ and they may not break the first time around, they may break on the 3rd pass or they could break on the 30 pass, it all depends on the tune, how well it was put to geather, the balancing, the hard ware used ect......

You would be happy with 450-500 hp rang i bet

Based on this:

I am looking to have a daily driver that is just damn fast. I don't want to die from driving it improperly but I do want it to put a smile on my face whenever I drive it and put my foot down.

then I agree with this:

Like I mentioned earlier - i have a 347 stroker, and although I don't yet know the exact HP I'm dealing with, I can tell you that it's plenty fast for a daily driver, and can get me in much more trouble than I should probably have available to me. 800hp on the street or anything close to it will either wind up causing you more trouble than its worth (that prob won't be on pump gas!), or you'll be frustrated because all you'll do is spin everywhere when you tap the gas. My buddy had a car like that and it was nasty and sounded incredible, and he'd lose it at 80mph if he modestly downshifted.

I'd agree with other folks on here and tell you to go to the track and the speed shops and start talking to people and making friends. Once you do, ask them to take you for a ride in their hot rods so you can feel what 400HP or 600HP feels like. Chances are you'll be plenty pleased with the former, which will then help you figure out exactly what path to take to reach your goal.

^^^^^^ this


I think a lot of people have no idea what an honest 500 hp feels like. I'm not talking about an eBay ad for a car that has heads and cam, and claims 500 hp. I mean a real 500 Hp. 800 hp is leaps and bounds above 500 hp. My engine makes 500, and it's mostly useless on street tires. A friend has a GT500 that made 786rwhp, and I got to drive it once. Talk about useless. It wasn't even fun to drive on the street.


The first thing you need to do is set a budget, and then you need a REAlISTIC goal. Have you thought about what you're going to have to do to your car to prepare it for that power? If you have a T5 just be ready for that to go in the dumpster.

[ALEXLOPEZ62188]

I talk a lot to the guys at GTR in rancho cucamonga, and they tell me a stock block, from Yeats of experience, handles 450whp safely. After that, it really depends how well it's put together and how you drive it.

As for your tranny, promotion has pretty decent trannys that'll handle up to 520hp for like $1300.. Plus core and shipping. It's a bolt on trans too

I personally sought out Astro Performance as I prefer a tranny that has 26 spline input shaft and will handle 580ft/tq all day out of a well built T5.
Also, it requires no modifications or extra parts to make it work(TKO's, t56s... Etc)

Not trying to thread jack, but I'm looking at stroking to a 347 and hitting 500 rwhp. Is it possible to do n/a and carbed? Thanks.

[GreenMustang00]

Why not? Its possible

yes, but it is not gone to be a friendly street car and you should start your own thread

[Nick_83]

will do

[ryanw]

theres nothing wrong with requesting some info in some one elses thread. just my opinion...im mean you dont want to completely take it over but i dont see an issue with it, i do it all the time ...lol

Stay on topic!




I would actually like to see that 347 500hp in a seperate thread so I can follow it. A guy in our car club is rebuilding is so i would like to know the potential of it with a carb setup

[DPadTTID]

I am trying to adjust my budget for a Boss or Dart block just so that I will have it if I do end up with a crazy end result. Don't know if I should add the forged crank into the budget but it would certainly help if I could somehow upgrade my cast for forged. My budget needs to expand a little bit.

Oh i agree...

i just dont want people to think that they can never ask a question about there own projects in some one else thread, a lot of the time the question that get answered help the original poster out any ways, ya know

[Danno]

Hey - I said that I'd re-post when I got my dyno results, so here they are:

366HP @ 5600RPM
396 ft./lbs @ 4100 RPM

This equates to somewhere around 430HP & 465 ft./lbs of torque at the flywheel (that's using a generic 15% loss equation for a manual trans - your opinions on that may vary).

There was some question earlier in the thread about "useable power" on the street...I can tell you that even at this modest amount of power, I'm able to (quite easily) lose the rear end of the car at 50mph if I downshift. That's on radials on dry flat ground so that might not be the case if I put my MT's back on. Either way, downshifting at 50mph and getting sideways wasn't quite what I intended to happen, so like I said - take a ride in a car that you think is powerful and see what you think before you go shooting for 800hp. I'm a little more than happy with my results...so much so that I'm now a bit timid to get into it at highway speeds!
