MULLET~BOY Posted October 2, 2003 Report Share Posted October 2, 2003 if you want to build a true 370 you have to bore your cylinders to .08 and use blaster pistions or or banshee pistions with the spacer plate witch is not worth it most people now days use the new wisco pistions made for the long rod crank they are shorter so no need for spacer plate and no need to bore the cylinders to such a big size for blaster pistions to fit making the cylinders 370 will not gain you much at and it's a wast of bores it's not the way to go the long rod crank will not gain u any hp it will move the torque around the power band it will reduce wear on the pistion skirts to tell you the truth i noticed nothing after i put mine in except that it cost me 10 bucks more for gaskets becouse i have the spacer plate :roll: so i don't recomend this mod if your looking for a gain in performance go with a nice 4mm stroker :wink: Quote Link to comment Share on other sites More sharing options...
gbf4ever Posted October 2, 2003 Author Report Share Posted October 2, 2003 what would i need with the stroker or could i just drop it in Quote Link to comment Share on other sites More sharing options...
boonman Posted October 2, 2003 Report Share Posted October 2, 2003 The stroker crank is a drop in unit, in itself. However, you will need porting to compensate for the longer stroke. For this, I would go to patriot racing. Also, I have a LR crank, I like it. i did feel slight differences in the powerband, it became smoother. I used the 795 pistons from Wiseco, and I don't have a spacer plate. If you have to replace the crank anyways, and can't afford a stroker crank, (they are more expensive than a stock or LR crank) and the porting for the stroker, than the LR is a perfect thing to do. The reduced rod angles will help reduce wear on the top end, and that is a good thing. I however, would NOT use a spacer plate. I do not like extra places for an air leak. That is why Wiseco now has the 795 pistons...... If you have the $$$, then definitely go with the 4mm stroker. Quote Link to comment Share on other sites More sharing options...
Oilsmoke Posted October 3, 2003 Report Share Posted October 3, 2003 Boonman So does the 795 piston work with a 4mm stroker long rod crank and a long rod crank too? or do you need a differnet piston for both? Quote Link to comment Share on other sites More sharing options...
PassionRE Posted October 3, 2003 Report Share Posted October 3, 2003 The 795 piston will work on the 54mm stroke long rod without a spacer. On 4mm long rod cranks, even with the 795 pistons ,either a spacer plate or redesigned domes will be in order. I prefer the plate over the dome mod mainly because the pistons will be protruding over the top of the cylinder top deck surface in the area of .080". This puts the rings just that much closer to the combustion heat and is a premature failure waiting to happen...Jim Quote Link to comment Share on other sites More sharing options...
Backcountry Posted October 13, 2003 Report Share Posted October 13, 2003 The rings are going to be X distance from the combustion process regardless of the deck hgt.... Quote Link to comment Share on other sites More sharing options...
Downside Posted October 20, 2003 Report Share Posted October 20, 2003 You the man, Dan!!!! The dome method is the way to go! You get the benefit of a little extra power stroke plus nobody knows what you have under the "hood". -Downside Quote Link to comment Share on other sites More sharing options...
