Re: odd ball engine combo
That's not so odd ball.It's been done. The 4.125 inch bore by 3.250 stroke acftually makes a 348 inch motor.The old 348 inch W motor had a 4.125 x 3.250 configuration as well. Three motors in the Chevrolet camp had a 4.125" bore- the 348 W motor, the small block 400, and the 402 big block. One thing- the mains on the 400 sbc were larger diameter than the large journal 327 or 350,so some sort of space saver bearing is necessary. The six inch rod is a great idea, as well as making as much compression as possible.I heard of a repair shop that came up with a 307 short block,.030" over from a rebuilder, then the customer opted for a GM Goodwrench crate engine. The crank in the 307 turned out to be a 327 steel large journal piece, so out it came to be used in something else, leaving the block, pistons, and rods. One of the guys in the shop figured out that a 3.480"stroke stock 350 crank in that 307 with a 400 sbc stock length rod would go together very well, making a 328 cu.inch motor that went into a Nova for a street driver. Wonder what the next guy that tried to rebuild it must have thought.
