347 kits are fairly cheep.

A kit with a cast crank and rods will hold more hp than your existing block, so dont waste your money on a forged assembly.

Ive seen them for as low as $850.

FYI--To make a 347:

3.40" stroke
4.030" bore
5.40" rod

Go to your local bookstore or library and ask for a book called "How to Build Big-Inch Ford Small Blocks" by George Reid

Thanks much fellas.

If you do a 347 there will be nothing original left about that engine, and it will no longer be a 302 so it won't match what the car calls for.

351FTW

you don't need to bore the cylinders .030" over unless the walls require resurfacing. even then you should tell your local machine shop to only go .020" over which gives you an adittional refinishing compared to the .030, as you should never take the 302 walls beyond 4.060.

If you go out to 4.060 your moter will run hotter. My 289 is .030 over.

69fastback · January 26th, 2007, 06:23 PM

My 351 was .040, and never had problems.

Katen · January 26th, 2007, 08:22 PM

what is a 302 bore at stock.

69fastback · January 26th, 2007, 08:49 PM

4.000

Horseshoeing · January 27th, 2007, 07:38 AM

I am not saying that you will have problems, but you are more likely too. If I had a block that need to be bore 60 over, I would do it in a heart beat.
On some chevy 283s, you could bore then .120 over and put in a stock 327 pistion in. I think they were called a 301.

Katen · January 30th, 2007, 09:41 AM

ofcourse it will run hotter your taking away the cylinder wall every time you bore it making it thiner. any i once again thank all that hellped me with the question i asked. once i get my engine an tranny done i will post pictures an things like that.
