Ive seen kits for 5.0 302 that will increase the 302 to 347 and there are tons of kits out there. What i was woundering was about how much extra horse /torque do you see when you stroke a motor. Is it significant or is it just a little more. Because the next motor i build id like to do it a bit different. But i cant see spening upwards of 2k just to stroke it if the difference isnt that great. Thanks for any input on this matter

I have the CHP 347 kit in my Mustang. When you are looking at the price of a kit keep in mind what you would spend on regular parts like new pistions, reconditioning rods, getting the crank reground, etc. After subtracting that a stroker kit isn't that much more. As stated above you basicly get a 351 in a smaller light package, plus you don't have all the headaches of a motor swap. The torque gain will depend on the rest of your parts. The above figure is pretty darn close to what I have seen with my Mustang. With more cubic inch you will want better heads. Even if you just port your stock ones it will help alot.

ok thats understandable... but if there isnt a kit how do you know how much more to stroke it without hurting parts and or breaking things. take a 351c for exsample how much more could you stroke it? as much as you want or will the crank start hitting the side of the block? i just took the 302 cause i happend to run across that kit
thanks

There's more stroker combinations for the 351W than I've seen for any other motor. The 393/351W is probably the easiest and cheapest of them all. Uses stock length 351W rods, stock hieght 302 pistons and a 3.85" stroke crank which will clear the block without any mods. To go larger you need custom length rods, and custom height pistons plus block clearancing. The largest 351W stroker you can get in a stock block with a .030" over bore is 427cu. If you have the bucks to buy a SVO race block and all the custom parts and work, you can go as big as 454cu.

wow thats amazing.. so with a 351w you can stroke it up to a 427 if you have the cash. Now with this extra stroke will that put more strain on parts and how much could you spin that? depends prolly on how much money you want to spend im sure but with a stroked up motor could you spin it as fast or faster then a regular motor?

Here is the best question to ask yourself what are you using the motor for? Street/strip, daily driver, hauling, towing, or racing? What you use it for will dictate. But in all actuality the rods are going to be swinging around in there a lot faster then the unstroked motor normally does. My suggestion is to use H or I beam rods for the piece of mind. Nothing worse then throwing a rod out the side of the block because of a weak rod.

thanks for the input now that you said that it makes sence and i never thought of it like that. I will be using the hi-po rods for that. The motor is going in a truck that right now is duel purpose a daily driver and a mud truck runner. Im thinkin in the near feature i might convert it for strictly racing but for the time being i cant aford 2 trucks so right now its both. Im just doing my homework on it right now because i just built a motor but the thought of more power is running threw my mind :
thanks for all the input and ill be reading up on this more
