Might be of interest . If you want to de -bur the internal of holes of all shapes without faffing about with a file and you haven't found this tool ..I highly recommend one. Works on S Steel ..tube..sheet metal.. bar stock ......... also you can go in from the outside of a closed muffler to do the back of a hole. The blade rotates in the holder as you trace the hole shape.

And i always thought those rivot nut things were for putting door mirrors on pickup trucks ,nice work sir .

If you do not want to shell out the coin for the installer tool that looks like a rivot gun ,i have some fastners at home you tighten with a bolt that squashes them also ,i will see if can find some samples for an image later .

I dont post on here often i thought id show what i did to my 440 muffler cover with 1/4" ball end mill. I know what your thinking
" itll burn the wood" i thought of that too, after the fact Lol, but actully ive run it quite a bit and havent had any thermal events yet. I may try and put a hood on it sometime.....or not.

Usually the conventional wisdom is to not port out the front, as some degree of back pressure is a good thing. However, your ports are not in line with exhaust port, so I think it looks real cool, and should work well.

How does it run?

I dont have a baseline bc i did the modifications first, i had to put a piston in it, so it runs fantastic but i didn't run it without the extra ports first.

I got a 440 with a dp muff cover, HD-2 filter, base gasket delete (.019 squish) and a timing advance. It runs real nice!

Straight out the front, in line with the ex port will make the most power mike.




This ain't no work saw, but works the best
