Frequently Asked Questions?
Can I run my OEM Oil metering pump with this engine? Yes you can, we recommend Premix for over 600RWHP
Can these engines actually make 800 Wheel horsepower? Yes we have made 820HP at 30PSI of boost with this exact block on a Bridgeport and E85, it does require an aftermarket Projay Intake. OEM Intakes restrict the blocks down to around 650HP at the same boost level.
How reliable are these engines? We recommend an ECU with Engine protection in conjunction with one of our Blocks such as the Haltech Elite 2500 with Oil and Fuel pressure sensors, this ensures that the block is never starved of fuel or oil as these are the only ways to damage one of our blocks.
Can I run this block at a lower HP level? Our blocks will support any power level from 100HP to 800HP with no issues whatsoever. The limiting factor will always be the supporting modifications and accessories.
