IMCA Modified Crate Killer

[Rogue1]

Looking for recommendations on what motor to build for a "crate killer" type of motor, big cube?, small cube?, we're looking for 500ish hp with a flat torque curve, and will be running on gas

406 got me exactly what you want, but I haven't ever heard of or seen anyone else build a 406 or post dyno runs compared to a crate where the killer wasn't peaky.. been a few from different builders on the same chassis dyno I use and nothing close to flat tq curve yet.





Mines for sale, I sold out in the spring and have this motor and two totes of small parts mostly new left is all.
