[QUOTE="dale.baker, post: 16488858, member: 113067"] I personally had JDM design, build, and tune on site my entire engine package. I removed and re installed the engine and broke it in. Jim promised me 800 RWHP before the build, Dyno'd 806 RWHP at 7600 RPM. You can see my car on the dyno on their web site. Five years later the car gets 19.5mpg with no issues and is a ton of fun to drive (See sig for mods). Lastly don't think you will hook up this amount of power without serious suspension modifications and drag tires with substantial side wall (15-17"). To answer your question I would send your complete motor to JDM and let them build it. Install it yourself. Have JDM recommend a local shop to work with Jim Sr. to remote dyno tune the car. As for rods the JDM/Manley H Beams have been used for years without issue on many of their sponsored Cobra Jet cars. If you have the extra money possibly the I-Beam rods will handle more than 1400 RWHP more reliably?Just my 2 cents. Hope this info helps. [/QUOTE]
