Keep an eye on our new "Customer's Rides" page as we add more and more super cool (and super quick!) Mopars running our Stroker Kits, Stealth Aluminum Cylinder Heads and other parts, as well as magazine articles and other builds featuring our products. Over the last decade, we have seen our stroker kits, heads and many other parts running in all 50 states and over 15 countries around the world! Thanks again to all our brand new and repeat customers.
Check out our customers running 10's, 9's, 8's and even as fast as MID SIX SECOND quarter miles with the same parts we supply in every stroker kit! Don't be scared or misled by the competitions sales talk and fear mongering, instead ask them how you can argue with these types of quarter mile times, and these types of RESULTS!
The November 2012 issue of Car Craft did a HUGE (6 full pages) build article on a 512 inch Big Block Mopar with our stroker kit, damper and flexplate. The kit dropped in the block with almost no clearancing, and they picked up an extra 75 horsepower. And, that was with mildly ported factory iron heads. A set of our Stealth aluminum heads would have really woken that thing up! Check it out at: http://www.carcraft.com/techarticles/ccrp_1211_rb_series_mopar_440ci_engine_upgrade_to_512ci/

"I wanted to thank you all for the help on the build of my 528 stroker. My engine was built with everything from 440 source (stroker kit, heads, rocker arms, water pump housing, valve covers, etc.). I could not believe the torque and horse power it made. It made726hp and almost 800 torque! And I did it all for less than $8000 thanks to your help with good prices and parts. I included a couple of pictures of the dyno sheet and motor with this email Thanks!"
Audy also has a '73 Cuda doorslammer running our parts that does 8.90's @ 150MPH!!
Audy says: "At the season opener IHRA national event in Baton Rouge, Louisiana, using a 440 source crankshaft qualified #4 in Top Dragster with a 6.65 @201.49 mph. We are expecting to test the limit much harder in the future! Not worried one bit about the quality of your parts that we have run for quite awhile with no failures. Thanks for good affordable parts!
