The engine set-up is from a crate motor company in north Jersey so I decided to give the drop in 383/450hp a try. They don't dyno every engine but follow the build specs of the ones they do. The engines are totally complete and hot run, broke in and timing set. They send you a video of the hot run before you take delivery (it's awesome!). I have yet to get the power to the pavement so more horsepower would only be futile. Check it out

for all the engine specs check the site, they have so many combinations and options for any budget!
