Built one a cople of years ago as a 454 and it made some decent HP..ask John Platania
..getting ready to do another..have a new block and some good old 074 heads,may try making a 496 out of it if there is enough room in the block. I used a solid roller in the previous one and it was a stormer...dammit why did I sell that car !!!

note: block uses bowtie block components for the lifters and timing chain
