wildbansheeboy Posted March 13, 2007 Report Posted March 13, 2007 Well here is the deal ,I got this motor and was told it is a stroker so i decided to dig in to it and see the rods say hot rods and the pistons are 795,s but the domes are not cut and the pistons dont go all the way to the top of the cylinders so i turned the motor over so the rod was at its lowest point and also did this to a stock lower end and the stock rod motor is shorter.any ideas what i have?

bansheeseat$$ Posted March 13, 2007 Report Posted March 13, 2007 Does it have a spacer plate under the cylinders?If not you have a stock stroke crank with +5 longer rod. Quote
sheefreak Posted March 13, 2007 Report Posted March 13, 2007 Does it have a spacer plate under the cylinders?If not you have a stock stroke crank with +5 longer rod. Yep! Unless you have a 10-mill cub casting w/4 mill crank in it, but not likely. Quote
wildbansheeboy Posted March 13, 2007 Author Report Posted March 13, 2007 I was a little sleepy last night I checked it out again and the piston goes all the way up and it dont hit the domes but close(the dome of the piston is above the cylinder but the out side edge is even) and thier is no spacer plate.The domes have not been cut.so is this a 4mm stroker with a long rod? do I need to have the domes cut or IS IT JUST A LONG ROD ? The guy I got it from has no clue what the hell it is the porting is a full drag port but don,t know who did the work? THE PISTONS ARE 795'S 4sure. HEADACHES Quote
sheefreak Posted March 13, 2007 Report Posted March 13, 2007 The top of my pistons stick right out of the jugs not just the dome of the piston. Sounds like you got hosed and it is just a long rod, not a stroker. If you want to check to see if it will run the way it is, bolt and tourque the head down. Get some thick solder and check the squish on it. You want a minimum of .035 and I don't like to go more than .042. Some people will argue this, but a high compression motor will sometimes detonate w/too much squish. Quote
man27 Posted March 14, 2007 Report Posted March 14, 2007 (edited) My hot rod crank has ck158b stamp on the rods and it's a 4mm stroker 5mm longrod it also has hr204 stamped on the crank webs.My pistons are about 1/8 of an inch above the cylinders without a spacer plate. Hope this helps :thumbsup: Edited March 14, 2007 by man27 Quote

Hope this helps :thumbsup: on the crank it s stamped h.r 204 & rods are stamped ck158 but has no B. Do you have 795's pistons? Edited March 14, 2007 by wildbansheeboy Quote
blaster668 Posted March 14, 2007 Report Posted March 14, 2007 You should be able to measure your stroke pretty easily. 4mm is easy to read even with just a ruler. Just mark where your piston is at TDC in the cylinder, and at BDC. Then measure between the marks... not a perfect measurement but it should be close enough to differentiate between a stock stroke and a 4mm. Quote
man27 Posted March 14, 2007 Report Posted March 14, 2007 on the crank it s stamped h.r 204 & rods are stamped ck158 but has no B. Do you have 795's pistons? Yes I'm running 795 series pistons your crank is 4mm 5mm longrod :beer: Quote
wildbansheeboy Posted March 14, 2007 Author Report Posted March 14, 2007 Yes I'm running 795 series pistons your crank is 4mm 5mm longrod :beer: Cool,but y is your piston height higher? Quote
man27 Posted March 14, 2007 Report Posted March 14, 2007 Cool,but y is your piston height higher? What is your piston height? Quote
wildbansheeboy Posted March 14, 2007 Author Report Posted March 14, 2007 What is your piston height? In your first post u said your pistons r 1/8 inch higher then your cylinders and mine are not just the dome sticks out. Quote
man27 Posted March 14, 2007 Report Posted March 14, 2007 That makes no sence to me if your running the same crank and the same pistons that I'm using then the pistons have to be above the cylinders because the 795 series pistons just allows for the longrod and the domes have to be cut for the 4mm stroke.I'm confused to bro maybe the pistons are stamped wrong. :shoothead: Quote

MAYBE IT IS ONLY A LONG ROD? Quote

MAYBE IT IS ONLY A LONG ROD? Cool down bro I meant that my pistons maybe stamped wrong I'm just trying to help you figure it out and all I can do is tell you what I've experinced when I built my stroker but I can tell you that your crank is the same as mine and if you don't have to cut your domes thats good for you !!!! :yes: Quote
