Now that’s a cool idle old school as.
This engine is one of our fresh builds. It’s actually 383ci it is a mild street build. She is running a new GM block (as we wanted to save the matching numbers one) it has a good set of roller rockers a great cam and a great set of roller lifters (HOWARD). We selected this cam as it has the exact idle and performance requirements requested by the owner obviously on top of his requests the needs of the engine had to be considered also. It is in the running in stages at this minute.
When this engine is run in it will produce one HP at the treads per cubic inch or a little better.
Keeping in mind this is a street setup that’s pretty good.
Just as a reference it probably didn’t make 150HP at the treads factory realistically
