3.5L to 5.0L stroker

I have done the search and nothing comes up. But, I have read on the prowler site about a 5.0L stroker from our 3.5 motors. Does anyone know how it is done??? Yes, I have emailed the Prowler guru but no response. I have heard of 300M that's got one but I can not verify that either. There is no substitute for cubic inches!

Gotta increase the bore and the stroke of the motor. The bore would involve increasing the diameter of the cylinder and thus the piston. The storke would involve using a crank with a longer throw, as it is commonly called. But htere is more to it than just throwing another crank in there to do this. Making sure the crank doesn't hit the block anywhere at the bottom, the skirt, is very important. Also the deck height comes in to play. I forget what the exact places to measure deck height, but it involves the top of the cylinder block and the cylinder head. You don't want the piston traveling upward and hitting the cylinder head either.

I got the concept down, Having built a 383 stroker and a 815. what I am more interested in the "what" componets are used. Is it a crank out of a 3.8, rod out of 5.2l, piston +.060 etc.etc.etc. Plus will the thing live punched and stroked that much? Generally, large strokers are rpm limited because of the increased throws and mass.

Hey dmondeac,

Yeah it was that prowler guy. I think I mentioned that engine in another thread talking about supercharging or the custom fuel injection system used on it. If I remember someone here commented on the fact that the engine was a 1st gen. I think that 5.0 was an iron block and it was sleeved. I haven't looked hard, but there wasn't very much information on the 5.0 at the prowler website.

Yeah, Lots of hype not much info and claims of 400h.p. I still have not gotten a response to my email. Guess I will call in a few days and see if I can get anyone to share info. I have heard of a 300M runnnig a big motor but I haven't validated the claim.
