5mm Stroker

[Capone]

I have a cool head with 18cc domes, and wiseco's. It seems like there is no clearance as it is between piston & head.. how would a 5mm stroker work? thanks.

 

btw, stroker newbie, if ya can't tell....lols.

first off i dont think youll hear much if anything about a 5mm stroker. it generally goes 4,7,10 and on up. 4 mm is the most common. to allow for the extra stroke you can cut the domes, which is the preferred method or you can use a spacer plate at either the top or bottom of the cylinders.

yeah, loco is right. the only time youll see 5mm is in a longrod motor. this is when the crankshaft has 5mm longer connecting rods on it. it doesnt give much of a powergain, but it does decrease wear on your pistons. in this case to allow for the extra length you run a special series piston. the wiseco 795 is what you need to run, if this is the crank you own, or just want to own.

Any added stroke more than +4mm and you have to have the stock cases trenched so they crank wont come in contact with the case. This adds a decent amout of $ to build a stroker motor. If you have to trench the cases, might as well go with a +7mm crank. Also you'll find the best deals (around $450) on the wiseco +4mm stroke +5mm long rod crank. Thats why most people run the +4mm crank. The only place I have seen a +5mm stroke crank in on banshee superstore.com. Theres a lot of other expenses that go with a 4mm strolker, ie stroker specific porting, domes, ect. Theres a decent amount of stroker info on past threads in the HQ.

I know of a 5mm stroker. You don't have to trench cases if you clearance the rod. 4mm is a lot easier to find, cheaper, and makes the same power.
