Guest super280z Posted October 3, 2002 Share Posted October 3, 2002 well shoot if you've got the parts and money for machine work, why not? from what i hear they still dont make that great power. the 347 and 302 are gret motors and have an awesome aftermarket. i'd just invest the better part of the money that it will cost ya to cut the crank into a nitrous system. ;D to each his own.

Guest jens Posted October 3, 2002 Share Posted October 3, 2002 The 347 stroker is not recommend for daily use because of the thin oil ring. I have build a stroker (not ford) but with very short pistons and thin oil ring it soundde like a diesel then cold because of the short piston skirts and used a bit more oil. A 351w with alu heads would be a better/stronger choice. The weight would be the same as a iron headed 302. You could make it a 392 with a 3.85" crank and 302 pistons.

74_5.0L_Z Posted October 3, 2002 Share Posted October 3, 2002 If you want to build a stroker based on the 302 then the 331 is the way to go. The 331 has a much better rod ratio than the 347, and the wrist pin doesn't interfere with the oil ring. I plan to build a 331 if I ever kill my 5.0 bottom end. My stock 5.0 bottom end has ~200,000 miles on it, and has never been rebuilt. I have a set of Edelbrock performer heads(P/N 6037), cobra intake, Crower 15511 cam, 24# injectors, 73mm MAF, and 70mm TB. The engine has taken me through the 1/4 mile at 112 mph.

Guest JAMIE T Posted October 3, 2002 Share Posted October 3, 2002 I agrees with what the guy above me said. The 331 is a better engine from a durability stand point. The 347 is just more popular. I think Coast High Performance offers a stroker 347 that has pistons that don't put the pin in the ring lands. But, it has a bad rod/stroke ratio. For only a few more pounds, you can build a 351W, and have serious durability. Stroke that to 393cubes with off the shelf parts. In response to the fist post, the 347 cranks are a dime a dozen now. It doesn't make sense to use an old Cleveland crank. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 7, 2002 Share Posted October 7, 2002 289 blocks have shorter cylinders than the 302 block and aren't recommended for long-arm strokers like the 347 and 357; the 331 is probably marginal. If you have a complete 289, you can use the Scat 3.25" cast crank ($275), prep your 289 rods with better rod bolts and .927" pin bores and use aftermarket Chevy 5.7" rod (1.42" comp. ht.) 383 Chevy stroker pistons. K-B/Silvolite's from Summit run $200 - $250. Check the piston skirt to crank throw clearance at BDC to be sure there's no contact. Quote Link to comment Share on other sites More sharing options...
