Stroker motors?

Stroker motors?
How much do they cost, how reliable are they compared to stock, how much power will they make at the Rear Wheels, and is there any downside besides the price? Wouldn't it be chaper to rebuild my heads and install some nasty cams? Or does the V8 not want to spend most of its life over 7,500 due to the oiling problem? Just doing a bit of re-search, any help or experience regarding em would be awesome

As for cost....it is not cheap..... Check this website

It lists a 6.4L stroker installed for $18336.00 based on a healthy engine to start with! I would imagine other shops would be around the same price. A supercharger is far cheaper....but won't pass smog either :>(

7K is far past peak power, so your gaining nothing except wear and possible 2/6 issue.

Why doesn't someone take an engine and build a ready to go stroker that is drop in ready and sell them with the exchange of your original engine. Just keep one on hand at all times rather then downing someone's car for months on end. I think some side money can be made there. I wish I had the room/knowledge/money/patience/tools/drive/motor/.........

Joe,
Easy answer. No one wants to lay up that kind of cash in "inventory" hoping for a buyer. Then you have the issue of what type of stroker, street or track. Then type of head work and CR ratio.
To many factors to build a stroker that can cost $15K-$25K!

I also think strokers are very much a custom built engine with many different intake-heads-cams-CR-pistons-etc...a 5.5-6.0-6.5 liter engine? Wide range of power too....up to 550rwhp (race engine) to around 400whp for a street legal automatic. Either way you get a mountain of torque down low.

We have the DEVEK B1 cams for 5l S4 and later. 1mm intake lift and 10mm exhaust lift. Mild increase in valve timing.
Adds approx. 30+ rwhp to a stock engine, broadens top end torque and is often used in strokers to add another 500-700 rpm to peak hp. Install requires changing valve springs.
