{"title":"Ford 302 Stroker Kits: 331, 347 \u0026 363","description":"\u003cp class=\"chp-seo-answer\"\u003eFord 302 stroker kits for 289 and 302 small-block Ford blocks: 331 kits with a 3.250 in stroke and 347 kits with a 3.400 in stroke, on a 4.030 in bore with 5.400 in rods, plus a 348 on a 4.040 in bore (have the block sonic-checked for 4.040 first). The 363 (Eagle 14003125, special order) uses a 3.400 in stroke on a 4.125 in bore aftermarket block. Every stroker kit includes the crank, rods, pistons, rings and bearings; each listing names its crank, piston and rod type. Build or fitment question?

The 331 and 347 kits need a 4.030 in bore (the 348 needs 4.040), so have your block sonic-checked and checked for clearance first; kits are 28 oz external or internal balance (see each listing), so 1982-up 5.0 engines with 50 oz parts need a matching damper and flexplate or flywheel. Not for 260 blocks: the 3.80 in bore can't safely be bored that far. 363 kits need an aftermarket 4.125 in bore block such as a Ford Performance BOSS 302; they won't fit a stock 289 or 302.\u003c\/p\u003e\n\u003cdiv class=\"chp-seo-table\"\u003e\u003ctable\u003e\n\u003ccaption\u003eDisplacement = bore x bore x 0.7854 x stroke x 8, rounded.
