If I ever do a 440 the very first thing will be a stoker kit... 512 cubic inches...
After that I'd play with heads ..

Im Looking at 400 to 500 kits. I plant to turbo it later using Aluminum heads and
And pistons to around 9.5 compression, using around 8 lbs If boost.with 93 pump gas. Do you think 9.5 will work. ?
