I am new to this website and I need some help. .. I am building my first motor and 347 stroker for my mustang sound good from a 302 block and i have not bought anything so far because i dont know what block to buy and exc.. people say to buy a race block but where do I buy one at. Does anyone know a website i can go to for a step by step on how to do that or maybe someone on here can help me? There was some things I am having problems with, like do i need a block with a 1 piece rear seal or a 2 peice, an I was told to use a 351 cleveland crank but I didn't think that will fit because i thought that was for a big block. Any help?

If you want a race block then go with a DSS short block. I like them. There are many place that manufacture aftermarket racing blocks and there are also many places that make complete stroker kits with the crank in the kit. The search engine will be your best friend on this. Oh and also check the magazine rack. The monthly mustang magazines are ALWAYS reviewing an aftermarket block. As for the how to. There are many people on here that can help you with any questions you have as you go through the build and there is also a few books out there that can tell you anything you want to know just for the 302/5.0 motor. Hope this helps Stan!

How much horsepower do you plan on making? That will be the deciding factor for alot of your parts. 500hp and under 7000rpm and naturally aspirated you can use a stock 302 block with an Eagle cast crank, Eagle I beam rods and a set of hypereutectic pistons. If you plan on making more than 500 hp and/or a power adder you will need to invest in a Dart or World block and forged internals. If you want to cut some costs you could build a 351 Windsor and use a 70s block. They will handle 700+ horsepower all day. What ever you do make sure you go to a good machinist. Good machine work and assembly is what makes engines live long. Stay away from 351 Cleveland junk. And no a Cleveland is not a big block.

that DDS block is still a stock piece.....

[fakesaleen]

get a used block because of the heating up and cooling down for years they are well seasoned and the steel is harder new blocks are not as strong and if you want power a seasoned block is the way to go

[Aliate X]

DSS motors are crap IMO. I would go CHP (coasthigh.com) really good stuff, and you can get them with whatever block you want.

If I go with a 70's 351 windsor block and stroke it, I will get more power and more then likely be cheaper then going with a 302 race block and build it. I am wanting to build a stroker motor for a 79 mustang lx no nos or supercharger. Just motor and get 550hp or more. But I dont want the best of the best if you know what I mean. $ is tight right now and I will be buying a little as I go. I guess I need to start by trying to find a 70's 351 and go from there. I have a motor here but not sure what it is, i have a friend look at it and said it is a old 352 motor from the 50's or 60's.. .. BTW the car will be setup to run 1/8 mile, the race tracks around me are 1/8 only......... Thankz for everyones input, been alot of help

I'll have a 425 for sale at the end of summer that makes 559 hp at the wheels and has gone 5.90s in the 1/8 mile in a 3100 pound car.

[vfast]

well if $$$$ is tight your not going to see 550hp's....you might be better buy'in the engine above which would have a much better block(351)

wasn't the 352 a truck motor?

352s were in trucks as well as full size passenger cars. 352 is an FE series big block which is the same family as 390, 406, 427, 428, etc. Its pretty much a useless motor. Not much of an aftermarket for it.

Nice vision but if you want 550 rwhp you are going to have to spend some $$$ expect $7,000-$10,000 for a setup that could get you close to that hp # any leff and it will be a ticking time bomb. Be realistic build somthing nice you can afford, don't throw alot of $$ at it than skimp when you go broke.

Here a few estimates:

Blcok + machine work and assembly and ballancing:
$2,000

Rotating assembly +ballancer:
$2,000

Heads:
$1,500

Valvetrain:
$750

Intake + carb: (Lets guess carb because it would be cheeper)
$600

Trans:
$1,500

Cooling system:
$500

Ignition:
$500

Fuel system:
$1,000

Expect more and if you don't do all thwe work yourself it will be much more. Just be true to your self and build what you can afford to finish, you will enjoy iy more.

kinda high..remember some used parts will work

That estimate is a little on the low side but might be do able with used parts.

you think?.......do we always disagree
I have 6500 in my whole car and is about 525 @ the wheel

I'm curious to the break down of this. Are we talking N/A or with a power adder?

[vfast]

I have a vortech s-trim also a tremec 5 speed, drag shocks etc the whole 9 yards.....

To see 550 rwhp out of a 347 you going to have to SPIN that thing. And with Hi-RPM comes high $$$ parts to deal with it.

I vote stop all the maddness get a 347 on a stock block and spray it with 100 shot and be happy. Cheep and works.

Well with a power adder it is very possible using used parts. If he can pick up a used s-trim he'd be set or a bottle for that matter. With my power adder I lay down just under 1000 hp at the wheels.
