Mine cost 350 with long rods and welding. Quote Link to comment Share on other sites More sharing options...

Ducman Posted November 19, 2004 Report Share Posted November 19, 2004 what does a welded crank do or like a +4 stroker and can my local machine shop do anything or do i have to send this stuff out 282706[/snapback] The cranks are pressed together; the rods are one piece not two pieces like on a 4 stroke. The cranks have a tendency to separate and/or twist so the 2 rods/pistons are out of phase especially on higher HP motors, welding the crank helps it resist separating and twisting. Your local machine shop could probably rebuild/ true and weld. Get price quotes and make sure they have experience and have done it many times before. Some shops do it very good fast and cheap which makes it worth sending out. For a +4 stroker, you have to buy a new 4mm stroker crank which adds 4mm of stroke, and takes displacement up to 370cc on the stock bore. It adds low end torque which can compensate for a more top end type porting. It needs to have porting specifically for the 4mm of added stroke. For this I would recommend getting it done by a very experienced and reputable builder. This route is a little more spendy, also you'll want many more supporting mods to take advantage of the potential HP in the 4mm motor = $$$ Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 19, 2004 Report Share Posted November 19, 2004 What he said... lol. Anyway, the biggest bang for the buck is good porting. If your crank is in good shape you could always get it ported. If you plan on putting a stroker crank in later because you don't want to spend the money now just let the builder know. They need to make sure not to take out metal in the wrong places. Quote Link to comment Share on other sites More sharing options...
