383 Project Engine for Sale.... Guys…
Looks like the time has come for me to finally pull my 383 project engine out of my C5.
To say it’s performed above my expectations would be an understatement and it’s reliability has also been rock solid.
Im moving forward with a larger displacement mill I hope to complete soon which will showcase the new 235 cathedral head I am putting the finishing touches on here at AFR. I hope to have the new combo on the dyno sometime before the end of the year.
Soooo….I will be selling my current combo after I disassemble, look everything over, and freshen it with new rings and bearings. Essentially it will be a new engine when I hand it over to whomever is interested. I can sell it turn-key in its current solid roller configuration, or turn it down a notch and install a hydraulic roller and 205 heads which should still clear the 500 RWHP mark and make even more low end torque. The bottom line is I am willing to set it up/build it in any configuration you may want so nothing is in stone.
In its current configuration it makes 610 FWHP with 523 Ft/lbs of TQ. In my C5 with an M6 and an efficient driveline it made 530-540 RWHP and 475-490 RWTQ depending on who’s dyno and the quality of the day. The nice thing about this package is it makes big power but is a little less likely to blow the tires off the road before the engine gets into the "jump to lightspeed" part of the power band. But even on Nitto’s in the lower gears on the street, going WOT early (so the car will hook), it can still violently blow them away when the engine RPM’s climb into the sweet spot (4500-7200 RPM’s). It would be a lot less likely to do that if you had the opportunity to heat the tires before hand.
For some of the newer members and others that might not have seen this, here is a thread describing all the original testing and engine dyno results of this engine back in 05’

Here is a thread discussing the engine in its final solid roller configuration on the chassis dyno a few months later….

And hear are a few videos of this combination in action…..the first only minutes after rolling off the chassis dyno discussed above….

The second, an “in car” vid of a track evening I attended last year where unfortunately I had issues with my linelock (no heater) which cost me an easy high ten second run (at a 1400 foot D/A) due to a much softer leave than I originally planned, traction, and high speed stability issues.

Note that this is obviously a proven and expensive combination to duplicate so please be realistic about potential pricing if you intend on contacting or PM'ing me. Basically I will be using most or all of the proceeds of this sale to finance the next build I am working on.
Im located about 45 minutes north of Los Angeles btw, and the engine wont be removed from the car for at least a few weeks in the event you live close and would like to actually experience it before considering your purchase.
Any questions just shoot me a PM or pick up the telephone....
Thanks,
Tony
