New motor


Before I get flamed I want you guys to know that this idea only going to be chased AFTER my car is one color and etc. So I know I want to make my car a whole shitload faster but I can't decide what would be the best bet. So basically I kinda want this forum to be an open one for all suggestions. I want to know what you people think would be the best way to get the most horsepower wether its buy keeping the 302, buying something bigger like a 351, converting it to a carb., buying crates vs building a block, or ? idk you tell me. Now as most of you should know by now because I always bitch about this: I'm NOT a mechanic so keep that in mind when suggestions ideas.

You can run consistent 10 sec 1/4 mile runs with a 302 based motor and a power adder. You could also make the same runs w/ a 408 stroker n/a. You need to determine budget, your goals, do you want it n/a or power adder. The simplest and cheapest setup would be a h/c/i 302 based motor with a blower on it. With the rest of the supporting mods to the car you'd have something fast. It needs to stay fuel injected.

Why not sell your car and buy one already done? If you look at the major mustang sites, like corral.net, h/c/i blower cars sit there for months. Owners ask ridiculous prices, like 10 grand or more, but they don't sell for anywhere near that. In the end it would save you a lot of money and time too. If you find a seller that doesn't smoke crack you could pick up a car already done for probably $8000 and it would be one color.

If cost is a big factor I would look into an Explorer motor with a couple goodies added on ( cam, roller rockers, headers).

yah, get a 302 out of an explorer or mountaineer. They come with the GT40 heads and intake and also grab the throttle body, its a 65mm. Usually mid 90's, but the head style changed during the run, some had GT40P's which require special headers and some are just GT40's.

Not being a mechanic and wanting to build a fast car is going to be a problem . You need a good fundemental understanding of what's going on under the hood with a high performance engine . Especialy with power adders you can't just add gas and forget about it .
My suggestion would be to find a high performance shop you feel comfortable with and build a freindship with them . Talk to them about what you want to do and pay them to get you in the right direction . Yes it's going to cost you ... but assuming it's a good shop .. it will actually save you alot of time and money from doing it the wrong way . Plus you will learn alot along the way and in the future you will be able to do it yourself .

I didn't necessarily say I was going to do it myself and my best friend/cousin is a decent mechanic but obviously not a speed shop guy. I would LOVE to do most of the work myself and get a little pride out of it at the same time but hey if I have to pay I have to pay no real way around that. This isnt really a topic (no offense) about HOW to get stuff down more like what I should do to replace/upgrade my motor but clearly being as inexperienced as I am I'll take any sort of suggestions.

331 or 347 with TFS heads shoot for 9.5-9.8-1 compression so it'll run on anything
Comp or Anderson roller cam
TFS or Edelbrock RPM II intake
depending on ci you choose,you'll wind up anywhere from 350-400rwp that you can drive anywhere & will be dead reliable.

I would go with Robs Suggestion. because with that compression you can add nos or a super charger or turbo later down the road. I would not go with the explorer motors.

if u dont care about gas mileage or streetability, go with a 408 stroker carburated with afr185s or even 205s, ull get more over all power with a carb but loose alot of streetability if u wanna stay cheap go with just a nice head cam and intake combo on ur 302, with 24lb injecters and a bigger mass air and a nice tune u shuld be able to get just over 300rwhp and u will not be dissapointed plus its alot more streetable then the aformentioned stroker combo

I respectfully disagree Frank about an H/C/I 302 being anymore streetable than the stroker mentioned. If idle quality is an issue, you can have cam with a 112lsa/shorter duration that will idle close to a stocker but will still plant your eyes in the back of your head.

Based on SOMETHING like this what kind of money am I looking at? I'm not saying this is definitely my solution but I'm also trying to gauge prices of different setups.

It will be more the $5000.00 If you factor in a good SFI Approved flywheel, Clutch, Balancer, Headers, oil pan, Induction system, etc.

When you get to the $5000+ range what your saying to do is still better than possibly getting a crate and just swapping?

My opinion is to build local,that way IF there ever was an issue,you could talk about it face to face. I'm sure the gentleman 2 posts up could build you something that would put a smile on your face.

I see alot of suggestions on the engine . What about trans , fuel system , rear axle , cooling sytem , ignition , etc ?

I don't know what your budget is , but you should consider the afformentioned question . From my own experiences having big power and a drivetrain that can't handle it is going to leave you on the side of the road .
The combonations for power is endless and can be confusing as to what route to take . Having stated that ..... pick a budget and try to stay with in it . 5 g's could get you an s-trim , a tremmec , upgraded axles and posi unit . Bolt it all to the engine you have now and you will be around 400 rwhp. Good luck with what ever you do ..
