Stroking a 306

Tony_90fox · September 28th, 2006, 10:58 PM

Alright what does it take to stroke a motor. it is all stock, just bored .030. i heard as big a crank for the money on another question. what else? this is a goal of mine...347. thanks

You will need crank, rods and pistons.

Tony_90fox · September 29th, 2006, 11:00 AM

any certain models or sizes? I heard something about 4340 or something like that. what about the pistons, does that mean forged? Sorry, but this is a goal of mine!

Go to engine kits, then click on 347ci. Those kits will tell you the basic internals that you need. The internals that are a must to make it possible are crank, rods, and pistons. The type that you get is all up to you.

Tony_90fox · November 21st, 2006, 01:54 AM

alright i found this post. My car is already bored .030 over. Is there anymore machine work needed with a kit from the link below if the kit is already balanced?

Also, i am getting the CNC ported Twisted Wedge heads, so will i pick the 9.00cc Dome Piston (Twisted Wedge) right??? sounds like i should but just had to ask.

Just get a CHP 347 short block and be done with it. Then stick on any combo you want as you will have a bottom end that can handle it.

My thoughts exactly.

CyberPrey · November 21st, 2006, 09:40 AM

Buying a shortblock can actually be cheaper in a lot of circumstances. When you get a shortblock, all the machine work has been done, and all the parts come installed. You dont' need to worry about anything other than putting in on your engine stand and bolting the rest of the motor together.

If you just buy a kit, you still need to worry about cleaning the block, getting the surfaces decked, having the pistons pressed onto the rods, having the cylinders bored/honed to correct clearances with the pistons, possibly needing a line-bore, getting the crank journals polished, and then assembling it all together and double-checking your main and rod bearing clearences..... And of course, there is always murphy's law could strike at any of these steps......

Stangzilla · November 21st, 2006, 11:01 AM

another advantage of getting a CHP short block besides price is that it is also blueprinted and balanced. I would 4 sure go the short block route from CHP..

Darrell · November 21st, 2006, 02:00 PM

If you find a good local engine builder and bring him the parts you will save a ton of money and have a much better product than a mail order engine. What happens when you have a problem? Is it easier to drive 8 blocks to Mr Local Engine Builder or is it easier to stick the engine in a crate and send it back to Mr. Mail order who can easily give you a hard time because he is 1500 miles away.

Tony_90fox · November 21st, 2006, 02:46 PM

I agree with all of you, if thats possible...i would like to have a new block but fellas, i dont have that kind of cash. And Darrell, i agree totally with you. i guess i'll just get the kit, and go from there.

Stangzilla · November 21st, 2006, 02:59 PM

I agree with darrell somewhat. but just a little note on the customer service at CHP i bought a complete crate motor from them and after less than 500 miles the cam bolt broke and scrapped the motor. after specking with CHP they told me that my motor was the first in 1800 blocks that came back. if that is true or not i dont know but they did make good on their motor and arranged a full replacement. Just for reference if anyone is planning on buying a motor from them. Whatever you do Tony at least make sure you get the kit from CHP you wont regret it...Good Luck

Tony_90fox · November 21st, 2006, 03:27 PM

yeah i remember the thread. Here you go, loan me the money and i'll get one. LOL!!!

So, just having my car already bored isnt enough?

Why do you need a new block? The block in my car is 32 years old!

Stangzilla · November 21st, 2006, 04:29 PM

Well it is the way a 347 is acheived is by boring the block and using a stroker crank. When you buy the stroker kit it will come with everything you need to make a 347. Someone correct me if I am wrong but if you get forged pistons they have to be matched to the cylinders? if that is true then you have to have the block worked on anyway. Not sure though. someone else here might..

Tony_90fox · November 21st, 2006, 05:21 PM

I never said i needed one, just would like to have one, thats all.

Stangzilla · November 21st, 2006, 07:19 PM

Well keep in mind if your are going as far as redoing your whole motor even though you are on a budget it is at least worth it to get your block completly checked out... it will prob cost a few hundred. So for a couple hundred its prob worth it to just get a new block.. just a thought

cali 5.0 · November 21st, 2006, 09:10 PM

how far does the block have to be bored in order to get 347,,
or does that have something to do with the crank throw

Stangzilla · November 21st, 2006, 09:22 PM

a .30 over bore and a stroked crank are usually the way to get a 347cid
