What sort of power you looking at putting to the ground with this project you have?

Sorry for the late reply. The warhawk 427 block will run on 110 octane (comp ratio of approx 13/1). and is easily capable of putting down 700+ rwhp NA. Considering the car will only weigh approx 2,600 lbs, I should have plenty of power.

The engine will run on Motec software, not the OEM computer, so I may actually dial down the HP while I sort out the car. I will probably have more power than I need initially!

2,600 lbs?! and 700 RWHP? That machine is going to need some wings! Why run this Motec software rather than OEM? Don't know so a little curious.

1. The car will certainly need some wings, ergo a splitter in front and the rear spoiler. The adjustment of the rear wing will be critical to the proper handling of the car. The rear wing alone can generate over 700 lbs of down force. The front splitter needs to generate 500+ lbs to properly stabilize the car. I.e. you don't want to overly load the front or rear of the car. Having over 1,200 lbs of addl down force on a 2,600 lbs vette is awesome.

2. The OEM computer is designed to run pollution control functions, and a host of stuff that's not being used on a race car. The MOTEC allows the engine to be fine tuned to operate better in a racing environs. You have much better control of the air/fuel mixture at various rpm and shift points....The Motec computer also allows data logging and data entry. Sensors installed in the engine and car, monitor temp, oil pressure, throttle position, rpms and other engine vital signs. The cool part however is the sensors all monitor g forces, braking, steering and steering wheel angle. What does that mean? You can create a track map and evaluate exactly where you are braking, coasting and accelerating at every turn. You can compare this to an instructor's pace laps. You can then determine if you are braking late, early, if your line is proper, early apex..... It's a great learning tool. Motec also allows you to run a sequential transmission if you decide. There's a lot more it does, but that's a good start. PS. The OEM dash gets ripped out and replaced with a digital LCD Motec dash, with shift lights and other diagnostics.

PS. One other cool Motec trick. If you decide you want to train using a lower horse power engine to rely on your cornering, braking and smooth driving skill, you can tell the computer to lower the horse power to say 500hp and it will oblige. You can literally dial in the power you want avail as a percent of maximum!
