Reply to "Destroked 351c into a 331CI"

If the crank you have has standard size journals, ie: it is not a stock crank that has been turned down to destroke it you could use the 302 Cleveland's 6.040" rods (which make Chev rods look like they are out of a lawnmower) and use short pistons. This combination is sometimes used in the 351c when a longer dwell period at TDC and BDC is desired.

I feel the longer rods do make the engine a bit smoother, but you have to watch the relationship between the piston pin and ring grooves and also overall piston design. Short pistons can rock unacceptably. A round skirt piston is best.

Or you could build a 302c using totally stock off the shelf parts with 4v heads.

302c's rev like mad and i've never heard of a bottom end failing on one.
