Default 302 build up.

So i'm getting a 302 for free, I want to build it up but i'm thinking stock displacement, but i have been wondering lately if maybe a 347 stroker would be more fun, I do like torque. I was thinking 1.6 roller rockers, forged internals, some sort of performance heads with head studs and bigger valves, trick flow intake, a new TB, a mild cam, and i am raising the compression too. I am just looking for some input about what kind of heads and where to get most of it and who from. My goal when i am finished is to be at 300 rwhp, if not a little more. any other suggestions you can give me will be great. I really want some good suggestions on what kind of cam to use since there are a lot of them out there to choose from.

I am also looking for a shell either a 91-93 or I really want the 94-95 body style, Just a few questions. if i can get a v6 car that has a blown up engine can i get like the 5.0 motor mounts and wiring harness and put the 302 in it? I really dont want to pay more than $800 for a shell (complete roller). I also am looking for a 5 spd transmission to put in it just for the fun factor, so any suggestions on what tranny to go with to hold up to all the power i plan on running through it would be great.

Thanks in advance for any help you can give me

347s aren't bad, however, due to their larger size, they do wear down substancially faster than other blocks, they're generally only good for about 100K then it's time for a rebuild. 331s are much more reliable as they don't put as much wear on the walls of the engine block.

Another thing to consider is going to be getting the right cam, but this will depend on what body style you get (foxbody) you can do pretty much anything (sn-95) you'll be more restricted to steeda and a handful of comp-cams due to their overly sensitive ECU. A good "in general" cam is the steeda #19, but if you get a fox, you can get the more agressive steeda #20 (I think that's it's number).

You'll also want a good balance of air flow, you just don't get random heads and start building. AFRs are very good flowing heads, but to comp you need a good cam to meet that head performance range, and good flowing intake as well.

Me I went the middle route. I'm using a stock cam (sn-95 here), ported GT-40 X303s, 1.7 roller rockers (these compliment sn-95s better than foxes as they add lift to the cam, but doesn't screw with the ecu any), ported upper/lower cobra intakes, 75mm TB (should have gone 70, this is my only mistake in the build).

Another thing to keep in mind when getting a cam is that you have to get the approprate push rods (length wise), and the proper springs for that added lift. Too short of push rods and you can't get the roller rockers will not seat properly on the rods and will not open/close the valves properly, too long and they'll open the valves too much. Get springs that are too weak for the cam lift (bigger cam stock springs) and they'll give too much and blow, too strong of a spring, and they won't give enough and cause other issues. So it's a fine balance you have to achieve.

Generally I'd recommend the following for a middle line build:
Eddelbrock RPM II Intake
70mm TB
1.7 Roller Rockers
Steeda #19 Cam
Eddelbrock Performer Heads

Now of course you can swap out whatever you wish. This setup will make about 5 rwhp more than my GT-40 setup (equal cams here, this setup would make around 25 rwhp more than mine due to the cam), but I like the GT-40 set up as I didn't have to do nearly as much modifing as I would of had to being that all 5.0 aftermarket parts are made for the foxbody, but have other parts that can be bought to allow them to be properly fitted to sn-95s.

Also, no you can't use a V6 base and drop in a 5.0, way too much work involved. Think of it like this, the V6 stang is built to use a V6, the 5.0 stang is built to carry the 5.0, you can just swap motors around and everything be fine, there's way more differences than that.

OK thanks, well I was looking into the gt40 heads and they are really expensive, being a college student and all I am really looking for something maybe a step below them. Also I was hoping to run the 1.7 rockers but I am worried they wont fit with the 347, do you know if they would fit or if i would have to use the 1.6s. If I have to ill go with the 331. one more thing right now what kind of specs do you recommend for a decent cam but still streetable and good for some decent power.

Like I said, there are a lot of variables that go with the cam, you first need to decide where you want the power:

1000-5500 RPM (stock)
1500-6000 RPM (mild)
2000-6500 RPM (aggressive)

You also have to have it match the intake airflow. You also have to decide what year you're going to get, cams that work well with 87-93s won't work too well with 94/95s due to the ecu in that year.

1.7s will work well with anything, as stated they add extra lift to the cam.

331 would be the wiser choice, you'll get good power and good torque and will have much better engine life.

GT-40 heads are cheap if you get them rebuilt/cleaned off of ebay, but I'd spend the extra few bucks and get GT-40 X303s as they're lighter, and flow much much better. GT-40s are only mildly better than stock and really not worth the extra cash. Because if you get a cheap uncleaned set off of eaby, by the time you rebuild them, you just bought a set of GT-40 X303s. Keep an eye on ebay, you can usually pick up a set of X303s rebuilt for less than $1000 and they generally cost $1000 per head.

So I deffdinatly want the power mid range (mild), and I am 100% going with a 94/95 body style car . So with that info any cam specs would be good. Oh and what company would be good for getting a forged crank, forged hbeam rods and forged pistons for a 347.

OK, then here's what you'll want to do:

Skip buying a stroker kit, cost way too much for the work, IMO, and you're hoping that the shop doesn't screw up the install, buy a stroker block (just the block) from haneymotorsports.com and go from there. Their blocks are warrantied and you can sell your old one, or keep it for back up, or even scrap it. You will need to salvage the oil pump system, oil pan, and other things from the old engine though, or you can buy new ones.

Cheaper more milder route as it requires less modifications due to fox body designed parts:

Cold Air Intake (BBK and JLT are really good, stay away from ebay)
347 Forged Stoker block
Steeda # 19 Cam
94/95 SVT or SVO GT-40 Intake (you'll have to buy on ebay, I doubt ford has it, no online stores sell them, they're rare)
GT-40 X Turbo Swirl Heads
1.7 Cobra Roller Rockers
70mm Throttle Body
80 or 90mm MAF (try to get Pro M for a 94/95, yes they're made, fox body won't work)
42lb fuel injectors
Head Bolts (DO NOT REUSE STOCK BOLTS!!!!)
Lower Intake Bolts (DO NOT REUSE STOCK BOLTS!!!!)
Thermostat Housing (good idea to get a new one)
Thermostat (good idea to get a new one, stock 180 is fine)
8mm 94/95 Spark Plug Wires (steeda makes a great set, just make sure they're listed 94/95)
Spark Plugs copper tipped (stay away from all others, and look at the head stats to get the right plugs)
New Radiator Hoses (you'll F up some of the stock hoses on the tear down, and it never hurts to go all new)
New Water Pump (not needed, but highly recommended)
New Timing Chain set (you'll need this is the engine doesn't come with one, never reuse a timing chain)
GT-40 Upper Intake to Lower Intake Gasket
GT-40 Lower Intake to Head Gasket set
Head Gasket Set (stock is fine)
Timing Chain Gasket Set (will include water pump gaskets)
Water Pump Bolts (do not reuse the stock bolts, they may not retorque properly)
New Distributer Cap (might as well swap this out, you will not need the entire distributer though get an MSD or other if you want, but stock is fine)
New Ignition Coil (also not a bad idea to swap out stock is fine)
BBK Ceramic Coated Headers (these will not rust and look great, nor will they discolor)
Your Choice of Mid Pipe (X pipes make more power, h pipes sound a little better)
Your choice of Cat Back (make sure to get stainless steel, my favorite is Magnaflow)
**upper intake and valve cover bolts may be reused unless overly damaged/rusted

That's all you really "need" to properly perform the swap, now the exhaust, and a few parts isn't needed, but is highly wise to add in there if you want maximum power. That list will put you at around 320 rwhp give or take a few and will require almost no modifications to anything you have now, it's a direct swap. Also, port match the upper intake to the lower, and the lower to the heads, this will make a GT-40 upper/lower intake flow extremely well and nearly as good as a Eddelbrock but without the hassel.

Now if you want about another 10-15 rwhp get the following instead of the GT-40 Intake and GT-40 Heads:
Trick Flow Track Heat Intake
Trick Flow Twist Wedge Heads
Trick Flow Intake Bolt Kit
Trick Flow Head Bolt Kit
Trick Flow Intake Gasket Set (if not included)
Trick Flow Head Gasket Set (if not included)
Trick Flow 94/95 Intake Elbow
87-93 EGR Adaptor Kit (not sure of it's exact name, but something may have to be moved, the intake will specify)
****Also, with this kit you may have to modify a few parts elsewhere, that's the problem with fox body parts.


Now if you want to really go big and save yourself a lot of money, because an N/A engine will cost more than an F/I, get a Vortech S/C and get a 9-11 PSI pulley and you'll be sitting right around 300 rwhp without all the work, or you can add it onto what you already have and be sitting at around 400 rwhp with a stock Vortech kit, or 420-430 rwhp with a pulley upgrade.

Yeah that would be the easiest way of doing things but I am going to build the stroker motor for a class that I will be taking next spring in school, so buying one already built would just defeat the purpose of taking the class. So that's why I want to know a good company I can buy the stroker rotating asembly from.

If memory serves me right, Eagle kits are one of the best, but generally speaking, any stroker kit from anybody will do, just make sure it's forged.
