OK, so we know that a lot of the guys are running stroked 351W blocks. We know its safe to go to a 408 (keeping the stroke under 4") Knowing that you have a budget (we all do) I would think the best options is to purchase a good 408 Stroker kit. Get a good kit that uses good parts. You wont be disappointed... I personally met a guy with a 351W stroked to 427. This short block was pro built. The guy didnt beat on the car but after about 2 years (summer use only) one of the pistons pushed a hole through the side of the block. He suspects this is from the heavy side load from the 4.170 stroke.
This is the reason that I decided to keep the stroke under 4" (personal preference). |
I got on the stroker heaven website. They have a 351/434 stroker kit using a Scat crank with a 4.000 stroke. Seems it would be safe to put this kit in my stock SVO block, being that it is at the 4.000.

Wow, thats a lot of CI from a 351. You may want to check out the required bore for that monster. I guess you would also want to check the max allowable bore for your block. Would you be pushing your block to its max bore with this kit????
|
What, are you just looking for trouble?? Check out the bore on that kit, 427supr. You aren't going to be able to do that with your block.
I don't get it. Do you have something against a 408, or what? I'm done trying to talk you out of doing too much. -Your money, your engine my man. |

Ssshhhhh. Not so loud, SPF1061! We all new he couldn't do it with his block, but I for one, am going to wait with a big smile on my face for his next post a few weeks from now titled: "Why did my 427w blow up?" :3DSMILE: :3DSMILE: :3DSMILE: :3DSMILE: :3DSMILE: :3DSMILE: :3DSMILE: |

Can't be done with a stock block. To get 434 cubes with a 4.0 stroke, you'de need a 4.250 bore. Good luck getting that out of a stock block. That's the max recommended bore for a Dart block. |
You guys were all belly aching about going over the 4.000 limit on a stock block. I find a 351/434 with a 4.000 stroke and now it the bore size. What's next, the spark plugs won't fit. I'm just kidding! Thanks for the info, I probably go with a 408.

Ford Motorsport website claims that their 351 based "sportsman" block can be bore/stroked to 427 ci. I believe it is a 2 bolt main. When you guys talk about a stock block, are you talking about a 351 "sportsman" block or your run of the mill Ford 351 block? My engine is a 1995 Ford SVO crate motor. Did Ford SVO make a "sportsman" block in 1995?
|
No, I believe the SVO motor was based on the marine block. Essentially a heavy duty version of the stock block. 427 is about the max cubes for that engine.
http://www.mustangandfords.com/techa...ine/index.html Like I said, I'm not afraid of a stock block 427 stroker. As long as you keep a good oil supply and keep the rpm's below about 6K it'll be fine. |
Yo 427,
I second, third etc. the opinion that a new block is the way to go. I went with the Dart Aluminum for my GT40. Here's a pic......Oh yeah Webers too. http://www.clubcobra.com/photopost/d...Engine_005.jpg And a stroked 351 to 418 with downstacks, fuel injection etc. for the Daytona... http://www.clubcobra.com/photopost/d...y_s418_002.jpg The Daytona engine was and is scary fast 560 HP 580 ft. lb. torque, the GT is a work in progress but, I have high hopes. TR |
That's a beautiful engine. I going to play it safe and go with the Ford 408. An Eagle 408 kit can be bought for around $900.00. That to me is affordable HP.
My wife finds beauty in jewelery. I find beauty in car parts. God definitely created men and women different. |
427Supr
Good choice !!! It will be plenty of power and very dependable!! Although... I really liked the looks of that Dart Alum with webers....mmmmm How about a little less jewelery and a few more car parts.... Just kiddin. Let us know how it works out. |
