[QUOTE="figment521, post: 8174184, member: 83932"] I and not against a stroker kit. It is just that the 4.6 has a good rod ratio with the stock stroke. A 5.1 L stoker kit is about $1600 and most still use a case crank A 4.6 L forged kit is about $1300. I personally would rather have the add strength of a forged crank over the add displacement the stroker. Then spend the difference on other parts (aluminum radiator maybe). Beside as a general rule the short the stroke the hard you can turn the engine. As for the compression ratio I would recommend staying at 9.5 : 1 or lower. The reason is that the higher the compression ratio is; the more heat the engine see. And the higher the boost is; the heat the engine see. So high compression + high boost + high air temp; all on pump gas can lead to spark knock on a bad day. Detonation will kill an engine. So for a engine in a truck that will see time playing off road I recommend an engine that is going to be very strong and very reliable. Mainly because calling for a tow truck can be costly, but the rates an off road wrecker charges is flat out robbery most of the time. What size tires are you looking to run? 4.88 are a good for tires 38" to 42" tall . I run 4.88 on my truck with 35" but I need to go to 38" [/QUOTE]
