Re: What to do witha a stock 351W
. The ONLY way you're going to get a noticable increase in low RPM torque is lots MORE CUBIC INCHES. Check out the various ways to get to a stroker 408"W... You can keep the stock heads (I'd do a little porting/correcting with a die grinder) if you're not after much more HP, just mainly torque... get the compression ratio up to 9.5-10:1 range... add a mild cam about 204/214 - 210/210 range... the stock heads can't flow enough for any bigger cam, you would just lose low RPM torque...
. If you just want to dig off the line quicker, put KB flat top pistons, Summit 214/224 cam, and 4bbl. carb./intake in/on the 351W and change to a 3.73 - 4.33 range posi rear end...
. Another possibility that is in vogue now is switch to a Ford 400 engine which is cheap in junkyards. It just needs 4bbl. carb./intake, 351C pistons, and a cheap 214/224 cam for musclecar torque/HP power! Some early ones have the smallblock tranny bellhousing pattern, otherwise 429/460 tranny. The 351"M/'400' also works by adding the 400" crank to the above formula.
