I am currently building a 351w that I am stroking to 434. I started to build the 408w but for the same money I can build the 434 so I went with cubic inches. If anyone has built or seen one of these, your input would be appreciated. answers to questions like durabality,and if you like or dislike it. Thanks fairlane999

Yea. I bought the kit from a friend who sells performance parts in MS. It's eagle crank and rods with ross pistons rings and bearings for $1400. It was the same price as the 408 .  |

What do you want to do with it?
Only racing or daily driver, too ?

well I'm finishing my race car. It's a 67 stang tube chassis, 4 8)link, 5:14 gear with the engine moved back 14 inches. But this engine i'm building is only going to be 10.8 compression so it's not impossible to put in a street car. Desk top dyno say about 550 hp and tq.  |

How accurate do you believe the DeskTopDyno is, based on your experience? |

In a production block that I assume you are using, how much of an overbore is that and what kind of wall thickness do you have left? I would imagine that stroker kit is more for aftermarket blocks? I would hate to open up a production 351W that much.

As far as the desk top dyno in my experience it's quite accurate. But you always have to take in consideration variables such as timing carb. induction and so on which play a major roll on engine output. On the question of how much bore is on the 434, I think it's only .060 but it may be less. I have to be honest I don't remember but I'll call and find out for sure. It gets its cubes mainly frombig stroked crank and short pistons. Thats why when building strokers you should be concerned with quality piston. Some are very lite and short and don"t have the mass to take power adders such as nitrous. The ones in this kit are ross and should be no problem handling a moderate amount of nx. As far as overboring a Windsor I've been told by old schoolers that a Windsor can be safely be bored as much as .120 over. fairlane999 |

Here is an excellent link..... http://www.alternativeauto.com/waterbox/wb_archives/351W_strokers.htmlIt is a little old and before the popularity of all the stroker kits available now, but the physics references still apply. One key issue I found intriguing is the issue of air flow. The question arises how to flow enough air in and out of an engine with big block displacement while using smallblock heads?? With forced induction I don't think there would be a problem, but normally apsirated the efficeincy is probably not going to be there. Steve |

I think some AFR 225 cc heads with some mild porting would be up to the task. |

I did find this in an ad for their heads..... "AFR’s new 225cc is the perfect choice for 347 through 427 CI windsors engines operating between 4500 to 8500 rpm." So perhaps that would do the job. They are specified as "race heads". Good to see you back Tom.  Steve |

because it's cheaper, if you find a big-block at a junkyard for few $$$. They're not that uncommon. They would also last longer, as the block is designed specifically with huge cubes in mind. 434 cube W? I dunno man, that would require a lot of stroke and bore. I wonder what the rod ratio is on that kit. |

I'm not sure about what the rod ratio is on this 434w. but I hear what your saying. I think I have an article somewhere on rod ratio and once you get above 427 on the windsor it becomes a little more criticle. Even though I'm sitting here knowing this I asume that the ratio becomes a bigger issue at higher rpm. so my thinking is to run the bigger cubic inches for the tq numbers and keep the rpm at or below 6000. I may be completely wrong but it's my backwards logic. If anyone has anything to add just jump on in...fairlane999

Damm, that's a biggun. If they'd of made "them' that big back when I was beginning the 'build a stroker' gig, I'd of probably built a huge'n like that as well. As far as wingin' 'em, build it for whatever the intended purpose, keeping THAT in mind, and you can make 'em do anything. I regularly wind my 418 past 7500 all the time. It's seen over 8 a couple of times as well....... |
