o.k, this is probably a dumb question but, which bore size would i need for a 347 stroker in a foxbody? 4.00 or 4.125? is one better then the other? Also, Summit sells these blocks for like $1863 plus freight charges of $120.00 or so But I found the exact same block for $1681 plus free shipping on Amazon.com. FUCK summit racing! ![[Big Grin]](biggrin.gif)

4.00 would be a std bore 347=342..but the 4.125 (big bore) would be a better choice

A 4.125" bore with a 3.4" stroker crank comes out to 363 cubes. Lots of displacement for an 8.2 deck block.

Dart says you can go 4.185 on the bores. There is no reason to go with a 4.00 bore when a larger bore brings more cubes and unshrouds the valves. A 363 is the new 347. No reason to build anything smaller unless you have some type of class rules restricting cubic inches.
