Back to how that 427 will drive. It is a good thing your last engine was the purpose built odd ball my 383 was. I drove the T again yesterday, looking for a business I had never been to in an industrial area. Boy do I miss how the 383 performed below 2000 rpm. The higher rpm is impressive but sub 2000 not so much. You won't have the same issues with the automatic with a torque converter that will allow above 2000 before really connecting the power aft. Since I will have to have a fabricator massage my hood to fit over this engine, I should have just had a sbc blower motor built with a small, low profile positive displacement blower. That is the only way I know of to get the best of both worlds, great low rpm grunt and the high rpm zing. Either that or ditch internal combustion and go with electric drive.
