There are several ways to build a 427C.I. stroker 351W engine. Will you ue a stock block or aftermarket block. If you use stock block you have to use a 4.187 stroke with a 4.030 bore, with the aftermarket block you can go 4.125 stroke and a 4.000 stroke. The larger bore and the 4.000 stroke works great. We have built these with 10.75 compression that run on pump gas and make over 600HP with 575 to 600ft/bls torque. The main thing is how much do you want to spend. The stock block way I recommend a 408 or 410 or a 418 which has a 4.100 stroke. We just finished a 4.100 stroke 4.30 bore 351W for a customer that made 600HP and 575ft/bls torque. this engine was done with a Ford Racing sportsman block, hydralic roller and will run on pump gas. This engine ran about 11,500.00 of the dyno. We do 408/410 stroker that make 525HP and 550ft/bls torque for about 5500.00. These 351W are the best buy going for performance for the dollar. Oh they will aslo turn 8000rpm's with a solid roller if that is what a guy wants. The pin does not go into the
oil ring on any of these combinations and
oil usage is not a problem. We have been doing these for over 10 years with great succes. Good luck, Keith Craft
