331 stroker and the beginnings!!!

[ToplessMarrine]

Ok so now that I have my 302 build in the works and on its way to being complete, of course I am not satisfied with stopping there.... So I have decided to embark on building my first ever stroker motor from the ground.. up!! So first off, will a short block work for what I want or can I use either, or how does that work. Other than that my metal worker/machine shop guy will take it from there for a little while.

[Silver91Hatch]

Well I just got done with my first stroker motor, stock block, Eagle kit, machine shop just like a 306, clearanced for the rods myself at the house, after that its just the same as a 302/306.

You lost me here. Are you asking if a stock block will work for a 331 build?

[ToplessMarrine]

I suppose I am, i just bought a short block 302 and didnt know if there were differences between a factory mustang block and a long or short block 302. I know a factory block is a 302 but thats about all I know and I know its considered a short block, but are all short blocks relativly the same.

[Wayne's 88 GT]

The difference between short and long blocks is that a short block includes the engine block, crankshaft, pistons and thats pretty much it. long block is the same as the short....but also includes cylinder heads installed on the block as well.
If you picked up a 302 short block there are some differences if it is not a 87-93 Mustang 5.0HO block. The engine block in your car currently is considered a roller block due to the fact it has a roller camshaft..........pre 85 5.0/302 blocks are non roller so you would have to use a non roller camshaft or get a roller block if you were going to use a roller cam.

Sounds like you are going to be having some fun with the vert...........keep us informed of the build!!

[ToplessMarrine]

Wow I feel stupid now, I actually thought there were two diffenet styles. Either length in the stroke meaning a long or short stroke or differences in the actual length of the block. I never knew it was just a "term" for with heads or without heads. God I feel dumb!! Thanks a lot, so I bought a short block meaning I need to purchase the stroker kit and whole top end, and first and foremost send the block for machining.:bonk:

[Wayne's 88 GT]

It's ok Matt......don't feel dumb...I know I've had my fair share of questions like that and I've been in garages and around cars all my life!

Do you know what year and model Ford vehicle the engine came out of?

[ToplessMarrine]

no i dont but the seller told me it was a non-roller block. But I've heard that you can convert to roller is that true or will I have to keep it the way it is?

[tripps88]

FRPP makes the conversion kit. It is fairly straight forward.

[ToplessMarrine]

Awesome thanks a bunch I'll check that out right now!!!

The only diff in the blocks is really just the 2 holes in the valley to bolt down the bracket that holds the dog bones in place.it will take you about 20 minutes to convert the block to a roller block or you can just buy link bar hydro roller lifters and just drop them in.

X2 :yes1:

Also remember if your building a 331, then all you would use is the block. You will be changing the crank, rods, and pistons. If you build a 331.

[ToplessMarrine]

I'm def. going 331 with it and I have already oredered the kit to convert it over. The question now is do I have to pay 450 dollars for the FRPP lifters or can I use different ones or are those the best bet? Also for a non-poweradder motor is 9:1 compression enough or should I go 9.6:1 or does this really matter. I want great low end torque and line leaving power but driveability with all motor.

if your running aluminum heads and always 93 i would go high 10's on the comp.

[ToplessMarrine]

Wow I havnt even been able to find a kit in the high tens. Any suggestions. I found a great priced kit with high grade parts but its 9.6:1 keith black pistons, eagle crank and such, like I said I love any info I cna get on this. Its my first stroker build, and I am all about all motor!!

[Notch93]

I believe Trai is a dealer for AD Performance. Have him look into a kit from them for you. And put forged pistons in, instead of those KB's.:yes1:

[ToplessMarrine]

Who is Trai and I was looking at that just now about the pistons I didnt even notice it earlier. Thanks for the help.

[Notch93]

Trai is nastynotchback1 that has been replying in this thread.:thumbsup1:

[ToplessMarrine]

ok cool I'll ask him.....

[XSR]

You may want to really look into having someone help you with this build. There are alot of things you will need to check, measure, and recheck to make sure its right. I would hate to see you put alot of time and money into doing it, and something major go wrong. I hate we never meet up, and Bones told me he forgot to get the heads/intake from you. I appologize, just let me know if you need anything. Also, I can figure up the compression, and order anything you may need. So just let me know!

[ToplessMarrine]

Thats awesome!! No worries on the meet up and I am kinda glad I didnt get you to do these GT-40s cause I'm gonna actually spend the money on aluminums for this build and may have you do the works on the heads and intake combo for it. As for the bottom end I have a local racing engine builder puttin together my bottom end, I am helping with it to learn and to take money off of his labor costs. But as for the top end and even knowledge as far as the compression and things like that... Well its anybody's business as for right now. But I do need the help and will def. be consulting you as well as others. Once again no worries on the meet up, I want you to be aboe to do the heads/intake for this build.

you will probably have to go with the 9.6 kit and have your heads milled to get the proper comp unless a kit with the right pistons can be found.i anwsered your pm and i will see what i can find for ya.Greg (xsr) may have more insight on the comp for you.one more thing is to zero deck the block for alittle more compression.

[XSR]

That's cool, let me know when you need info/help. If you need any advice on the topend parts, I'll help anyway I can.

[ToplessMarrine]

ok so far in my trek to find the kit that I think will be good I have found a fully forged, 28oz. balanced Scat 331 stroker kit from AD Performance with 10.37:1 compression with a 58cc head. So I also searched to find out that my personal favorite head the AFE 185cc head comes in a 58cc chamber. So any thoughts????? I know there is much more needed but as for the big stuff, any thoughts??

[XSR]

Is there any reason for not wanting more out of your combination? I think I can set you up with something real close, and make more power. With parts that you can grow with in the future. If you would like to discuss it more with me, you can pm me.
