275 hp reliable?

There are many boosted slants running stock pistons and rods successfully.
The tune is important.
dont shave heads or deck block less thay need it then just do the minimum to clean them up! gonna want invest in forged pistons figured to 7ish to 1 compression! as mentioned above need a cam designed for super charging! what type charger you thinking? and you going blow threw carb or some type of efi??? boost levels? stock /6 take 8 to 10 pounds and live a lil while but sooner or later youll be buying forged slugs for sure!

Hello, Linked is a post that mentions a couple of well known slant six racers that have not have issues with running stock slant six pistons and rods with boost

Dirty white boy, please provide a link to support your claims that stock slant six pistons and rods will not support low to medium boost with proper tuning,

here is quote from one of those posts "get well above 400 HP with stock-type internals, but I like to take my time and not blow things up."

I know Lou and have raced against Lou,, so Dirty White Boy, please respond with evidence to your insight. Have you ever been a participant in a Slant Six . Org Drag Race? Please respond with where and when.
