Well I have a couple of questions.

1. What is stroking a engine? Do you just get thinner pistons or something?

2. IF i could spend about 2k on a engine, should I keep my block and have it overbored (and maybe stroked) along with finding some GT-40's heads (and isnt there GT-40 intake also?) I would also get some Headers.

Besides that I would keep everthing else from the old engine.

But honestly I dont know how much it will cost to take my block to a GOOD shop and have them over bore it and then get new pistons and some good pistons rings and rods and prob crank.

Im would love to get all machined parts, but i know cranks can get quite expensive.

Im looking for all the info, since again this will be the 1st engine swap ill be doing.

OR.... should I call up summit and get a fully rebuilt engine?

Only thing about that is do I have to pay for shipping my engine back to them (the core)?

If not summit what else are some good sites online that offer engines (or crate's).

3. If I bought a block from a site for like 1300 (a HO block including pistions, crank, and roller cams.) from a site, what are the most warn parts in a engine that ill need to replace/ check from the part from my current 302 with 137000 on it.

Thanks a lot for all the help, and im sure you guys are getting tired of all these questions, its just that we all wann learn from the best, and do it right the 1st time.

Again, thanks!

1. "Stroking": changing the stroke of the engine (longer) by installing a modified crankshaft, conn. rods, & pistons.

2. If you're gonna drop that kind of money, get a warranty. Jasper offers 100Kmi and 3 years. Think about it.

3. See #2 and your own post: "...do it right the 1st time."

 

I took my block, heads, and crank into a machineshop. Bored .030 over new exhaust valves, new injectors, keith black silvolite pistons, crane truck power cam pn#363904, and hedmann shorty headers pn#89470. Damn thing runs like a raped ape. It hasnt run this good since I bought the truck. 1991 silver anniversary bronco with 31's and e40d. The machine work including pistons, valve job, and all new bearings was only 11 bucks. About 360 bucks for the cam, springs, and double roller timing chain(all from crane). And about 430 for the new injectors(19lb) and headers. All the parts were ordered from Summitt. It was money well invested. I bet I make 75-80 more hp now.

 

So Red all you did was pull out your block (Including heads,cams etc.) and fixed it up and reinstalled everything?

Seems pretty simple.

 

This nails it! If you are going to replace your crank, (you should replace your rods anyway) that is a good time to stroke an engine. You can save some money by not going with forged pistons. The forged pistons are needed with blown and NOS engines because of melting the darn things.

 

Youngblood. now is a good time to put a 351 in. This is what i just finished a couple of weeks ago. I found a 95 roller cam 351w complete at a yard with 80 thousand miles for $800 bucks. This motor has lots of life to go and when its done then i will stroke it. you would have more grouth potential from the 351 as well. but if your happy with the 302 i wouldnt stroke it more than a 331 if your looking to get more then 60k out of the motor.

here is another site you should look into, you could get a 302HO
http://www.ford-motors-engines.com/index.html
this site has a 7yr/70,000 mile warranty. cant beat that.

 

Well i would love to get a 351.

I know its been asked 100 times.

But what is all different since you did it.

I know the computer is different.

And is the bellhousing the same along with everything else?

So like you, if i was to goto a yard, get a 351, complete with EVERYTHING cept tranny, for lets say 800-1500 and bring it home.

What would i need to make it work properly?

Thanks Kemical

Well , what you need to get is the correct flywheel with a 28oz balance. if the motor is complete from intake to oil pan all you would really need is the computer for a 351 . your wiring harness from the 302 will be used and if the 351 didnt come with brackets you can use the ones from your 302 as well. I made the mistake of getting a 95 motor that needed alot more stuff to make it work because it was out of a mass air truck. so I had to change the distributor including the dist cam gear. I have an AOD tranny so I had to locate a flywheel from a crown vic that had a 351/aod combo. so long story short, if you find a 351 that is from 93 and earlier you should be just fine. make sure it has everything on it . here is a great thread for you to check out .
