Well i know my buddy paid a nice amount and i have yet to whitness but he was just telling me how his 306 goes to 10k rpms ..

budget isnt one ,how fast or slow i build the car is the main factor . im getting m other car ready to be my daily driver and this one ready to be rebirthed ,its a hatch and im thinking of getting a vert or a coupe body , likely a coupe because it lighter, my car has salveged title and has seen the track has a roll bar but im doubting the frame is as straight as it appears,(wouldn't be to much to get it straightnened but the salvaged title and the damage that's done already puts a limit to how much i actually want to do to it). For a project its fine and i plan to cut out the damaged rear quarters and widen them my self along with a nice set of wheels . If i go with a new body and rebirth it im going to be very timid on touching the body if there's no damage there already.

That's some thing different though (building a custom car)
The 351w would be nice but can anyone say if the extra touque would allow me to have an overall faster car ,was looking around and saw alot off 400ftlbs that sounds like it could be promising even with 240-300hp . im talking stock heads at the moment .
with a stroker kit and balanced ..
should this make for a 11 second car ?

 

Well if budget isn't an issue, why are we talking about how to get a 302 into the 11's? Why is a 351w build considered expensive?
Surely you have a price in mind, otherwise why not drop 35k for a new GT and be in the 11's with a stock car only using sticky tires?

stock head 351w won't let you run 11's. Won't get you any faster than your car is now. Also, a 351w isn't using a stroker kit, unless your taking a 351 and stroking to 363, 408 etc...

You really need to sit down, think, and write down some concrete goals. Saying you aren't worried about budget, just a fast car, won't get you anywhere. You NEED to have concrete goals. Once you come up with those exact goals, we can start to make some progress.

 

well a new gt is out of my reach at 35k so yeah there's budget yet im looking to work it slowly to the point where every thing should in my budget. or like i said i'll be saying forget the mustang and starting elsewhere ,im not the kind to just give up so im hoping it dose not come to that.id like to be able to have my 23-24 year old car run with the best of the newer cars. I'm 24 myself so the cars are the same age as me.

and the 1st goal is to have the car/cars in the 11s without spray and be solidly built .I have already began to look at an 05+ mustang v6 or not and doing a coyote swap in the fox so there is a few routes i can take that will make a big change and keep me busy.

If i were able get some beasty race ported e7s and they will be able to get me in the 11s then id do it but every where i look it just best to go aftermarket.(i haven't ran across anyone that says they can do the job) and a then there's the block limit /rpms.

Im just trying to take it steps at a time and not backwards steps . so if i could build a 10k rpm 7k+ rpm engine as my buddy has (which i don't think he knows who did the work on the engine ) . the block seems to be the the major limiting factor here so what kind of block will i need ? will a dart block be up for it??
if so ill just get one but keep the stock one i have and build it until its ready to be swapped over and can handle the task & by then id hope to have a 10 second na /9second boosted street monster . Dont think it'll be my daily driver i have other cars for that .I'd like it to nice enough to drive on the street if i wanted to /needed.


Yes i was talking about a 351w then stroking it.A stock headed 351w would be any faster? i thought id be able to benefit from the cubic inches hoping to gain a nice amount of torque.Where would it it help to be any faster ? what would it take ?

 

The amount of money you're going to spend on race ported e7's + springs + valve jobs is going to be ridiculous. Start looking into the aftermarket. You'll spend the same and aluminum heads are 1/2 the weight = quicker. Give us a ballpark amount on how much you want to spend

 

I have never heard of e7 heads running 11 anything!

You WILL waste time and money if you buy a dart block hold it and stroke a stock block then swap it later thats DUMB, the aftermarket block will yeild much higher bore capacity then your stock block, plus with aftermarket block it would be worth the extra money for a forged crank!

Forged cranks in stock blocks are DUMB! You can use one in a 351w stock block since the power limit is much higher than a cast crank is good for!

Get the dollar amount and a set goal and get back to us! you are all over the map on this thing!!!!!!!!!!!

Money, block, use, end goal, start the build..

 

Im trying to take it slow . The forged crank stock block would just set me fourth from having a stoker and only needing to upgrade the block in the end. i know im all over the place but this is not something that just came about ive been looking for a nice upgrade for a while now .with the goal of an 11 second not over done car , as i said before i have talked to guys and the tell be how the have hci and nitrous and still only run 12s maybe a high 11s i feel there's something wrong there and don't want to make that mistake.

The engine mods im thinking of are bored stroked ported and raised compression but id like to run 91 pump gas so im sure i can go crazy on the compression.

im not looking to invest in this and it all blows up or runs a 12 in the end . im aiming for 11s to begin with , then 10s, then high 9s all over a few years time

Getting back to where i was .Going with some aftermarket heads and a good balance job & upgraded valvetrain dose not leave much more to be done correct me if im wrong.
well besides the obvious fuel up grades which isnt much and likely done with the heads.

i also named this thread engine modifications because im steering away from bolt ons
. ill be going with quiet as possible mufflers and as much stock appearence as possibly in the end . i know ill loose some hp but there bolt ons and i plan on having cut outs

Now not lowing my goals but to get a bit of progress here . there are 350hp topend kits . now stepping up the head size , would that = out to that being the same as porting the 350hp kit?

and low 12s high 11s can that be done with the 350hp topend kit ?
if not should a balanced and squared bottom end do the trick for high - mid 11s?

 

I agree, take your time. It took me close to a year to piece together my 351 build, and another 1 1/2 years to build it. And yes, aftermarket heads and stroker/balance job is expensive $$$.

FWIW, I love sleepers

 

I am getting a little confused here. You keep coming back with the same questions that have already been answered.

Yes, low 12's and high 11's can be had with a top end kit... I already said that a page ago.

You are not going to go very fast with stock stuff, no matter the porting. You can balance, rebuild, square the bottom end until the cows come home, but that alone isn't going to get you magically into the 11's. You need a healthy bottom end, no doubt there, but a bottom end isn't really responsible for making power.

Even with aftermarket parts, a 302 N/A is pretty much limited to the 11's. Fastest I've seen a 302 run N/A is 11.2, and that was with 335rwhp and the car was on an extreme diet (~2800lbs w/driver I think, for reference, a stock car is around 31-3200lbs + driver).

If you want 11's, a nice top end (like the 350hp) and good suspension + tires will get you there with a 302 and some slick driving. Now you mention going 10's, and then 9's... a 302 N/A will NEVER get you there. If you want to go faster than 11's with a 302, you need a power adder (nitrous, supercharger, turbo), but then comes the questionable reliability of the stock block at said power levels.

Want to do 10's, then 9's? You need more displacement. Start with a 351W, stroke it if you want, put a good, matching top end on it (also make sure the bottom end is healthy too) and you'll be able to make all the power you need. Proper suspension and good driving... you're set. Of course, big HP has lagging effects on everything else. Bigger fuel system, stronger tranny, chassis strengthening etc.

Really, all of this was explained in the article I linked to you already...

I think you should check this guy out... www.fordstrokers.com
Tell him your goals, he'll get you there no problem.

 

Sleepers are cool . stroker and balance job isn't to bad from the one shop i call so far . i need to find more places and shop around . i know of a couple other race shops near by ill be giving them a call soon.

i know there is a bit more to it than just going with an hci that's why i may have asked a couple times more than once I did no try to just seemed like the thread was getting off track. 10s& 9s are a would require a another block i got that part . One reason why its not my focus and 11s are. I have 2 foxes and may be getting/building a third if all goes well if not i may just keep 1 and start elsewhere as said before.
going with the 351w would open up room for the 3rd fox yes all in all i have to many cars already another stress on why the build has to be on point.

Is there a down side to running a big heads on a 302?

 

If properly cammed, no. I mean, you don't want to go with HUGE heads, but 185-190cc with a matching cam will be some real fun, contrary to general belief. Then you can always plop them down on a larger displacement motor later
