How would You build a 416 stroker 340?
« on: June 02, 2006 - 06:58:04 PM »
Ok so, I've had some downtime with my car recently and it's had me thinking about the engine. It leaks, it runs poorly, it needs cleaning... it's just time to do things right.

Now, I've been looking and thinking hard and have decided that the direction I want to go is with a stroker. The motor is a 340, it has been bored 0.030 already, and I'm hoping there's some left for another machining to smooth things out. I also have an 833-od 4 speed with 3.55 gears and intend on keeping it that way.

I have a budget of about $3000 plus extra for little things if I need to.

I loooooove torque and wheel spin. It's why I own a muscle car!  :burnout:

The engine currently is in partial-stock trim, stock unported heads, stock exhaust manifolds, LD4B intake, Holley 650 Double Pumper. It's also running some after market flat-top pistons (Speedpro I believe) and eagle rods with stock crank ground 0.20. Camshaft is a MP 292/508 and its nice and lumpy, but absolutely no low end power below 3000rpm's. It absolutely kills my brakes, but after its warmed up they are workable.

Other parts I already have and don't wish to give up are: Edelbrock RPM Air-gap intake, MSD 6AL Ignition, Blaster SS Coil, Pro-Billet distributor. Down the road I may purchase some TTI headers as well.

So, my question to you is this....

If you were to build a stroker 340, that's drivable on pump gas (Keep in mind we only have 90 octane here in alaska), and usable with power-disc brakes... how would you do it on a $3000 budget? Is it even possible?

All options are open!

Enjoy!

It is not a Numbers matching motor unfortunately, that's the only reason I'm willing to do this.

And the want to keep it a 340 so it's at least partially matching is why I'm making it a stroker instead of a 360.

I would buy a 5.7L Hemi insted, you could find a nice one for 2k and then just a fuel sell and some stuff and for 3k and some work you have a Hemi. I got my complete 5.7 Hemi+tranny for $2500...

 If you go stroker it would probably be best to get some edelbrock heads.

You got alot of room for more power without even going with a stroker though.
 Do you know what compression you have? hopefully at least 9 to 1
 You could just rebuild the 340, it sounds like the bottom end beefed up.
  First thing get rid of that 508 cam!, and find something better. Engle makes some good cams and Chryco speaks highly of them so that would be my first choice.
You could get some 308 heads and have them ported or better yet some edelbrocks(make sure you bump up the compression if you go with the edelbrocks).
 Get some TTI headers and a nice free flowing exhaust with x pipe.
 Use the Airgap intake and a 750 Holley DP, maybe bigger if you stroke it.

 I'm in the same boat, I have a tired low compression 340, that I may go stroker or may just rebuild it with higher compression pistons etc. or I may just...........

A $3000 budget might be very tight.  The crank, bearings, rings, gaskets and pistons are going to be over a $1000 plus you may need an overbore/honing and balancing which could run $500 - $700. The kits are not "bolt on" IMHO and some additional machining may be required (mine needed $500 in extra machining).  You definitely need headers and a good exhaust system whether you build it stock or stroked so there is another $500 - $1000.  The cam has to go and new heads or some head work should be done.  You can do the head work yourself if so inclined.  A good rebuild is a must. There are some very good articles on 340 and 360 build-ups.  Look on Comp Cams and Hughes Engines web sites.

Where did you get a 5.7 hemi and trans for 2500?

I'm also in process of rebuilding a 73 340 motor. Many configs are floating through my mind and the stroker motor is one of them. Still need to verify if it is in fact the matching numbers motor 340 in the car, if it is I am considering rebuilding back to specs. Which would be 8.5:1 comp but I would consider some mods, cam, a set of J heads I have with 2.02 / 1.6, intake, new 4bbl, etc.

If it is not then the stroker is totally on the plate.

I understand that I have more 'room for power' with my combination, but I'd rather have more usable power and torque in a lower rpm range. As I've said, It's a street car and it's meant for fun, not entirely drag racing. Higher RPM's are rarely seen.

As for the new 5.7 hemi, I don't much like those and don't want to buy a rate motor. I want to keep it as a 340 casting since it is a 340-S.

Reguarding bore and honing, I was considering those separate costs and not part of the 'build' itself due to it being almost 100% needed for any engine rebuild anyway. Mostly, this was a question about what parts and pieces to use, or if kits would be best and which ones people have used.

However, that's not to say I haven't gotten anything out of your replies. I do appreciate your help and reading what you have said!

Thanks alot guys! Your help does not go un-appreciated and un-noticed.  :thumbsup:
