how is a stroker motor made? What needs to be done/ machined or that kinda ****?

 

usually just an overbore but ive heard of sometimes having to notch the bottom of the cylinder wall to clear the crank depends on how far your taking it

 

Actually the ford 302 comes stock with a 3" stroke on the crankshaft. Aftermarket kits are available that will increast the stroke of the piston from top to bottom. Usually this means a longer connecting rod and relocating the wrist pin location so that the piston won't collide with the head. If you want more power I would suggest you start with what heads you are running as this is the running base for your flow. Cam, intake, and exhaust come after that to be tuned with the CFM's of your long block, stroked or not.
Genarally the modded engine running efi may need a better fuel pump, adjustable fuel pressure regulator, larger injectors, and better ignition systems to make a world of difference. I would suggest that you think about how quickly you would like to run the quarter mile and then you will hone in on the heads, bore, and stroke to run. Cam, intake, and all the rest come into play after that.

 

you can lengthen the throw of the crank, lengthen the connecting rod, bore the engine, change the pisition of the piston on the connecting rod. all those can add up to different types of strokers and displacement. as for notching the cylinder walls, that because of the crank when it rotates it has such a longer throw it cause the connecting rod to hit the cylinder walls, meaning you need to notch them out, most of the time u need to do this with a 327 stroker motor and also anything bigger than a 400 cubic inch with the 351;'s...

 

new crank, rods and pistons.

 

Hey Blackmage, nice sig picture. im guessing that was before you went to go buy new tires?
