stroker ? for the engine guys
I have my 400 crank turned down to fit the 350 block, I have the correct damper for the 400 crank, and I just wanted to make sure the flywheel from the 350 will work. ???? It is a manual trans 72 4x4.
Thanks, Jimi |

Re: stroker ? for the engine guys
NO! The flywheel will not work as stock. In fact I dont think any 400 sb was out of the factory gate with a manual trans. There are adapters for this application though. The 400 must be balanced front and rear. Or have the whole crank assembley balanced, and use the 350 balancers.

Re: stroker ? for the engine guys
You can order a crank that is internally balanced for a stroker motor, but a stock 400 crank is externally balanced and a 350 flywheel or flexplate will NOT work on the 400 crank.

Re: stroker ? for the engine guys
You should have the entire rotating assembly balanced anyway. Are you going to use 5.7 rods or 5.56 (stock 400) rods? Forged or hyperutectic pistons? There are a lot of thing s to concider when it comes to balancing an engine. For the street an external balanced engine is just fine,dont waste your money on having a stock crank internally balanced.

Re: stroker ? for the engine guys
After my last experience of a rod through the side of the block on my stroker motor, I recommend that you get a quality brand of rods and a good crank when you build the motor. I put mine together with the 5.7 rods, both times; but this last build went together with H-beam rods and a forged crank. The other crank received damage when the rod started doing it's own thing in the block. We chose stock rods the first build and the rod gave away just above the mounting journal to the crank. As I stated above, you can get an internally balanced 400 crank and the one that I ordered this last time was just that. It was not much different in price than a forged externally balanced one. The previous crank was externally balanced and worked just fine on my street truck, but it is now in the salvage yard.

Re: stroker ? for the engine guys
One of the problems of assembling all the parts/pieces at home is the individual takes on more of the risk of [failure from] the pieces not playing well together. Building from scratch is great for the technically knowledgable or the person with a fat budget to work with. But if one or both of those are lacking, it may not pay in the long run to take that risk. These days you can get a balanced stroker rotating assembly for not a whole lot more than it'll cost to assemble all the finished pieces yourself. I'm personally well able to build a stroker from scratch. But were I wanting a 383 today, I'd either buy an entire rotating assembly from a reputable company, or a complete shortblock with a warranty.

Re: stroker ? for the engine guys

Re: stroker ? for the engine guys
as far as i know 454 flywheels have the same balance as 400s, and they definetly bolt on.

As noted, a balanced assembly is worth the money. Note that a matched balancer is required. Am I missing something in this debate about how easy they are to find?

Re: stroker ? for the engine guys
Best bet is aftermarket on the 400 sb flywheel......try Northern autoparts for a stock replacement(cast flywheel), or Hays ,or Centerforce (billet) can be had for a few more bucks. IIRC, my Hays was around $225, & Centerforce was a tad more. The stock replacements were around $120. I would rather go this route, than bolt a balance weight on the rear.....but DO be sure to have all the pcs balanced with the crank

Re: stroker ? for the engine guys
Best to have a balanced assembly. Solves most of the trouble.

Re: stroker ? for the engine guys
i think you missed the point crazy longhorn, the 454 flywheel WILL bolt onto the 400 crank, but is the balance the same or not is the question now.

Re: stroker ? for the engine guys
the concept of the 454 flywheel came up because it may be easier to find a 454 flywheel than a sb 400 but since the balance is different it is not a good consideration.

Re: stroker ? for the engine guys
Thanks for all the input. I guess I'll have a couple "tree-fitty" flywheels for sale on E-Bay soon.
