There are a lot more pistons available for stroked low deck motors than stockers. Now that there are dedicated strokers for the low deck motors, there is little reason NOT to stroke one. The reason 383s weren't typically stroked in the old days was because of the extensive machine work necessary to put a 440 crank in, and then net only about the same cubes (actually slightly less) as a stock 440. The bore and stroke combo of a 496 mopar is EXACTLY the same as a typical big block Chevy 454 stroker combo that is very highly regarded, with thousands of them running around.Įdit. Lighter pins, lighter pistons, any quality rods you care to buy, more room for stroke increase with less block grinding, lighter rods, all of which contributes to longevity and power.įinal displacement around 470 seems to be a sweet spot, but I wouldn't be afraid of a 496 in a 383 block. I would not consider a stroker kit for a big block mopar, 383,400, or 440, that didn't use big block Chevy rods. Here is a video where you can hear it running on the street. 050 Intake 254 Ehaust 260Įddy dual plane intake (Chose for more torque and clearance issues vs RPM)Ĭomp Cams 1.5 Ultra Pro Magnum Shaft Mount Roller Rocker ArmsĬrower Severy Duty HIPPO solid roller lifters(high pressure pin oiling) That said, I have been very please with the power and durability of my 496 so far. Well, that's not entirely true.he would offer it but said if you want it you are going to pay for it but the price for it would be cost prohibitive for any potential buyer. ![]() It is so much of an issue in fact, my engine builder said he would never offer a 496 again because the work involved was just to extensive. So the cost goes up considerably unless of course you are a machinist or know one willing to do the work. A lot more machine work is going to be required to make everything clear. Get your crank (4.25' stroke), pistons and rings for your overbore and the longer rod - that is basically what the factory did with the 8.1 ltr to get the rod to stroke ratio to 1.52. The block clearance is an issue with the 496. You can use the same pistons that a normal stroker kit would use (6.135' rod) if you use a 6.535' rod, plus this give you a better rod to stroke ratio.
