bansheelover Posted March 29, 2004 Report Share Posted March 29, 2004 hey guys, im lookin into a +5 longrod and whatnot and i was just wondering if i need to mod my cases for that to work, i know about the spacer plate going on the bottom and that i should get my jugs ported for the best outcome but can this be done in a stock case?? Thanks if im missing anything, please let me know Matt Quote Link to comment Share on other sites More sharing options...
boonman Posted March 29, 2004 Report Share Posted March 29, 2004 I'm not quite sure what you are driving at here. A LR crank is a +5mm longer rod length. The stroke doesn't change. Wiseco makes a "795" series piston which sets the wrist pin 5mm higher in the piston to accomodate the longer rod length. No case work is needed for this crank. I run one. I know. Now, for a 5mm stroker crank, you will need slight trenching of the case. you can drop in a 4mm, but not a 5. Porting will be needed to fully achieve the power gains of a stroker, but not needed on the LR crank. Quote Link to comment Share on other sites More sharing options...
bansheelover Posted March 29, 2004 Author Report Share Posted March 29, 2004 ok so what im lookin at here is a "Hot Rods Long Rod Crankshaft Assembly" . I will not need case work done, all i need is the 795 series pistons and portwork done. what cc's would this bring me up to? anybody know??

Matt A Long Rod Crank Wont increase the engines CC's, the long rod just makes a smaller angle between the centerline of the piston and the centerline of the rod when the piston is at the lowest part of the stroke which reduces the side load on piston skirts and adds reliability and potentially piston life on a high performance ported motor. It also increases dwell time where the piston is at the top and bottom of its stroke. I has the same questions a while back in this thread Quote Link to comment Share on other sites More sharing options...
PassionRE Posted March 29, 2004 Report Share Posted March 29, 2004 370cc on stock bore up to 397cc on 66mm bore.....Jim Quote Link to comment Share on other sites More sharing options...
Ducman Posted March 29, 2004 Report Share Posted March 29, 2004 370cc on stock bore up to 397cc on 66mm bore.....Jim Thats for a 5mm stroker crank right? The question was about a 5mm long rod. Quote Link to comment Share on other sites More sharing options...
PassionRE Posted March 29, 2004 Report Share Posted March 29, 2004 Ducman ..Sorry, misread the post..those specs are for +4stroker. Standard stroke long rod displacements are the same as stock cranks. He threw me off with the "Wiseco Hot Rods" verbage...my mind went straight to stroker long rods...Jim Quote Link to comment Share on other sites More sharing options...
Oilsmoke Posted March 29, 2004 Report Share Posted March 29, 2004 Here Here Jim You can't tell me all you only think about a Long rod strokers do you? Hehehehe Jim what Numbers am I Looking to get with my combo, apox Hp & torque? Quote Link to comment Share on other sites More sharing options...
