Lowest cost 400 stroker

Doh! Good catch oh builder of Chevy big blocks! F it, call Icon and have some made. The longer cranks are the same price at 440source.
 
We researched 427 pistons for a 383 stroker , no worky

Nothing that couldn't be solved though...
 
Very very interesting!

What about oil pickup clearance? I've read somewhere that above 4.15 stroke you're looking at interfering with the oil pickup?

Also BB chev Pistons. Interesting but wouldn't I have issues with the valve reliefs?
Pickup interference above 4.15, if you use Mopar rods. Use a crank with 2.2 rod journals for BBC rods, 4 3/8 fits.
I'm building a 440 based 522, 4 3/8 crank, 7.1 rat rods, Ross pistons.

I'm definitely going to have to dig around the 440 source site now. I mean that's a long arm there. Can you say 500 ft lb at 2500 rpm? :eek:
 
Haha since when is it about need? I wanna do a 4wd burnout with 37's. The parts will include front and rear d60 axles. Transfer case TBD.

37's and a rear D60 with enough power for a 4wd burnout? Might want to rethink that rear D60, get a cheap 14BFF instead, that 60 won't last if that's the abuse it sees. (Also a Jeep guy here, broken many axles)
 
Yep, I'd have to agree 440 source is the lowest cost. There are a few other options size wise available. 451 is a great choice.

13 year old inner self visionary vs reality are often very different matters
 
Mopar Muscle did some comprehensive testing...& porting.... on the BB production heads. I still have the magazines. From what I recall, once ported they were all pretty close in flow #s.

Yeah the problem is I know Jack about real head porting. Beyond mild bowl blending and maybe a little port matching I'd get out of my depth real quick
 
Lowest cost stroker 426 ci. would be offset grinding a 383 crank to bbc rod journals, use a 6.70 connecting rod & 1.485 compression height Pistons from 440 source That would put your piston .015 under deck & leave it
If you wanted to step up to a bigger cubic inch later add a 3.915 stroke crank to make a 470.
Just a thought, or offset a 440 crank to bbc and same rod, just use a 1.32 ch piston
 
Stay away from the 4.150 crank in the low decks unless you use something shorter than the 6.76 rod. There’s not enough CD on the piston for any real longevity out of the rings (I know I ran one). I’m partial to the 512 kits myself if spending the money ( I’ve built 3 of them with source kits). Great combo, big torque, drops right into the block with just a touch off the oil pump boss, and they don’t cost anymore than the smaller motors. You may be able to peice a 451 together slightly cheaper but it’ll take some leg work.

Doesn't the 512 use the 4.15 crank though?
 
If you have a crank grinder in your area a stock iron headed, factory 3.75" stroke crank 451" is the least expensive. You can use factory rods, etc.

The next step up would be 440 source heads with the springs, guides and valve job checked.

If you wanted more cheap cubes a factory 3.75" crank can be offset ground to 3.915" to make 470" with a 6.535" BBC rod.

If you didn't want to use a factory crank you can go aftermarket at 4.15" or 4.25" stroke/2.200" BBC rod journal with a variety or rods and shelf pistons available. The 4.15" stroke would allow for more oil pickup clearance if you are using an internal oil pump pickup.

The 4.15" stroke crank has a very similar compression height (or CD or CH) to a stock Chevrolet LS3. Nothing to worry about unless you have other problems in my experience.

actually most of the 4.150 kits have less clearance because they use the big Chrysler rod bearing. I haven’t looked up the specs on the LS3 but right off the top of my head I can probably guarantee it’s a smaller bore with tighter P/W clearance and less stroke so it should be less subseptable to the issues of the 400/499 kit. Not quite apples to apples. I get what your saying though. I’m just not a fan after running that kit. I’ve talked with others who also had the same conclusion. Now if you used a kit with the Chevy rod then yes is see no issues like I mentioned above.

I built a 523 stroker in 1980, waaaaaaaaaaaay before any of the stroker kits were available. I used a 440 crank welded up for a 4.375" stroke.

what did you use for pistons, rod length ?

There's no way this would make sense these days with the off the shelf stuff available. But still very cool that you were doing this stuff back in the day! Hat's off to you!
 
Thanks 416.
I am in Australia & we just do not have the access to parts & services like you guys do in the US. So we have to improvise...

Fishmen,
I used off the shelf 460 Ford pistons. Had the pin holes enlarged to take the 440 pins. Used 440 rods.
