albatross Journeyman Posts: 28 From: NZ Registered: Sep 2001	posted 09-10-2001 05:41 AM Thanks, had a look there and in the Ford parts manual and wonder about cast Vs. forged, stroke ratio and piston speed for a stroker above 393 since we've elected to run a 6-71 blower. IP: Logged
albatross Journeyman Posts: 28 From: NZ Registered: Sep 2001	posted 09-12-2001 06:10 AM Thanks 7DMach1 I think I'm going for the Scat 4.0" or 4.1" crank and H beam 6.2 rods, Why did you go for eagle rods and what's their website? I dunno about the pistons yet (JE inverted dome?) as I need around 8 anna half to 1 for the 6-71. David IP: Logged

Cranks and rods like described would be a tight fit in a 9.2" block. The 351W block would have a lot more room with its 9.5" deck.

I have a buddy with a stroker cleveland, it has 6.2 inch rods with a 3.7 stroke crank and the pistons for that combo are extremely short. The pin is way up in the oil control ring land. I dont think a 6.2 rod will fit with that much stroke. IP: Logged
DutchD58 Gearhead Posts: 110 From: West Milton, OH Registered: Jul 2000	posted 09-12-2001 04:51 PM Just exactly how are the oil rings supported in those long rod/stroker applications where the wrist pin intersects the ring lands? And what are the implications and consequences for piston/cylinder bore longevity in a 3000-5000 mile per year street/strip motor? Kevin IP: Logged
Mpcoluv Gearhead Posts: 928 From: Charlotte NC usa Registered: Apr 2001	posted 09-12-2001 06:01 PM There is a steel "spacer ring" that bridges the gap. I have seen aluminum piston buttons with the ring groove in it on extreme strokers in old Car Craft magazines. IP: Logged
kid vishus Gearhead Posts: 4357 From: middle of NC Registered: Oct 2000	posted 09-12-2001 09:49 PM His motor uses the buttons since the pin is pretty high into the ring land. Not sure how well that would hold up in a street type appliciation that sees a fair amount of miles in a year. IP: Logged
albatross Journeyman Posts: 28 From: NZ Registered: Sep 2001	posted 09-13-2001 02:03 AM Scat have recommended a 4" stroke and 6" rod or I could drop to a 3.850" crank or hunt down some shorter rods. I'd like to stay with the Cleveland block. David IP: Logged
