At one time, this engine was in my 99 Trans Am. The car weighed 3350 lbs w/ driver then and this engine with less compression and a smaller cam ran 6.10 @ 110 in the 1/8 with a best of 9.70 @ 135 in the 1/4. This was with a th350 trans, 4.10 gears, and MT drag radials. This was 5 years ago.
The engine ended up wiping a lifter out. After sitting for nearly two years, we ended up selling it to a customer after rebuilding it to his specs for a small shot of nitrous. We upped the compression to just over 13:1 and upped the camshaft to a custom solid roller from Cam Motion with 264/274 duration @ .050". I don't recall the lift exactly, but it was around .720".
The customer was an over the road truck driver and basically never had time to run the car, and when he did it would break a new part of the driveline each time lol. After the last broken axle, we ended up purchasing the car. He did manage to make his Camaro run a 6.00 @ 120 mph in the 1/8 a couple of years ago with bad traction issues on MT radials. His car also weighed roughly 3300 lbs with driver.
On the chassis dyno through a very loose converter the engine did manage to make 598 rwhp on motor. With a 200 plate shot (carb style nos plate) it made 806 rwhp completely blowing through the converter. The converter would flash to 7200 rpms, so I'm sure it would have made much more power if we had ever dyno'ed the car with a proper converter. This was also through 3" exhaust to the axle with Imco single chamber mufflers (flowmaster copies).
This engine was using all top notch components, but the rest of the customers car left much to be desired.... In the right hands this engine has 900+ rwhp capabilites and mid 8 second passes just like it is.

All that is necessary to complete this engine is an ATI balancer, some fuel injectors, a water pump, and a 4150 throttle body. I would suggest replacing the oil pan with a Moroso just for piece of mind. I work for Tick Performance in Mooresville NC and I assembled this engine. We can provide any of the additional needed parts and handle the install of the engine if desired. Certainly we can't warranty any race engine of this caliber, but you can trust that this is a good engine as my reputation would be on the line otherwise. If local to us, we'd be glad to go to the track with the buyer and help out any way possible.
Asking $10,000 . It would cost more than this to build a basic iron block 408 with some decent heads and budget everything else. Just the lifters, rockers and camshaft in this engine cost over $3000 new. C5R heads sell for $4000 a pair un-assembled. According to the previous owner, over $3000 was spent modifying the SB2.2 intake and fabricating the intake adapters. Darton Sleeves cost $2600 installed in your block. Custom Diamond pistons with tool steel pins were over $1000. Callies racemaster crank goes for over $1500. We're over $15,000 and haven't even covered the con rods, pushrods, gaskets, titanium valves, springs, main studs, head studs, port work, or machine and assembly fees. One could easily spend $20,000+ to duplicate this engine.
For more information call the shop at 704-660-5843.
Thanks,
Jonathan

Anyone wanting to kill *ss at the track needs to jump on this. I spoke extensively to Jonathan about this motor and was very, very impressed. I wish there was a way it would fit my application (DD street lol).
