OK, does anybody make a piston that is 3.91 bore and 49.53mm tall? Or does anyone make a piston that is 4.04 bore and 62.23mm tall? Trying a couple different ideas here. Bear with me :)

This, in my opinion is one of the BEST small strokes you can do . So simple.I've been doing this for almost 20 years. Mopar has a cast 3.58 stroke crank for the 318/340 mains,costs less than having a 360 crank turned and stronger. Then New I-beam rods can be had for less than re-doing the old rods. Now you need pistons = 3.94 bore W/ the 360 wrist pin location. Keith Black will put the wrist pin anywhere you want it.Not bad price too. Here,s one for ya.3.94 bore. 3.58 stroke and frst-gen viper rods(there 6.221 long).Killer low to mid range torque with a 1.749 rod ratio. I hate to bust anybodies bubble, but on the sreet you'll be hard press to tell a 349 form a 360,power wise.just like my 390 and a 408. NEVER tell the difference.
