holy ***t! if that thing is as light at the superlight r500r its gotta be doing high 2second 0-60 times now! but seeing that has alot of metal and the superlight uses alot of carbonfiber pieces id say its as heavy as their roadsports. i had the idea of using just the 3800 block and running a twin turbo setup in one of these cars. you can buy the kits less the engine and trans which is great for different types of setups. but wow, ive love sevens for a long time and finally see one with the engine it should have. im still amazed and would love to see some video if the guy ever gets some.
**edit** oh yeah the 454 would be too heavy, the lighter engine with all that power would be the best thing to do.
