A few questions about stroker small blocks

Good analogy Rob! The as cast stock Edelbrock is OK for mild hopped up small block engines until about 370 cubes. No big cams.

If your 340 is worn out of your just looking for added power, the stroker needs a good head. A ported Edelbrock will provide the airflow capability as well as the LAX head well ported.

Other head options that state better flow would be the Edelbrock Victor head and the trick flow head. Be aware of the hidden costs. Or odd part that may go with the head upgrades.
