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????

I just took a look at this site. Here's a quote from the first page under the section:
"IMPORTANT INFORMATION! PLEASE READ!"
>>Some large Ford stroker engine kits (& other brands) may require stroker pans and the use of a aftermarket block. <<

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?"

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?
