spirit of the 1/4 mile quick list - N/A 346
My motor went again and while talking to someone about installing forged parts (crank, rods & pistons) into my N/A 346 ci motor was told that if I went that way (forged), I would now automatically be in the 346+ category. Is this correct?
Currently I am in the Internal Engine Modifications - Head/cam -> 346
so without changing the cubic inch of the motor I would now have to compete with the -> 346+ NA category which are all larger cubes then the 346.
What is the intent of the Internal Engine Modifications - Head/cam
-> 346 list?

No clue.
Although wouldn't it be normal to hone .005" over? Isn't that standard practice?
The CID increase is puny. But establishing a good round bore and installing Pistons with a much fancier than stock ring package is worth hp.
Fancy parts could also be lighter. Again worth hp.

I had started writing out a reply to agree with Ron, but during my typing, my thought process brought me to the other side.
For a bolt on only car, no way you can open the engine and stay on that list. I don't care if you've just cracked a piston and replace it and the rings with OEM stuff, it's been opened, it no longer qualifies.
For a head/cam car, it's assumed that you're going into the engine to make performance upgrades. If you elect to keep the original displacement, that's up to you and you compete against others with that displacement. I feel you should be able to do whatever you want inside the block, provided it stays a 346. Some people don't want to do the things necessary to be at the top of the list, some do.
Look at the NHRA stock/super stock cars. You know there's been 346 powered C5s in the low 10s and even at least one that had run a 9.98.
So, my vote, that doesn't mean squat, is to allow any internal mod and get on whatever list your displacement places you.

well, to be fair sir... the first one had quite a bit of miles on it and you pushed it pretty hard, correct?
Looks like a good parts list for a nice engine. Good luck with it.

yes sir sure did, cutting oem pistons probably wasn't the best thing either 
That motor had about 55K on it when I picked it up - ran it pretty hard for a few years.
The original motor had 120+ K miles on it before it went. I had gone 10.76 with the original one before it went. that one was UGLY!!

So Pete what your saying is you can do anything in your motor (all forged) and as long as you stay at 346 cubes and nothing bigger you'll stay in the 346 head/cam na category? Just checking cause I'm forged , h,c,I,e but still 346 we kept stock bore cause we rebuilt it at 2200 miles in 04 when bought new.Just making sure.

Pat, yes that is what I'm saying. I don't make the rules and my opinion doesn't really mean much of anything. It's just an Internet list anyway.
I think this list is used by people to see what a combo is capable of. It's up to that individual to decide if they want to pay what it takes to be on top. Most don't give to ***** about being on top, they just want to see where they stand against similar combos.
One other thing to consider is the C5Z list.
Once you get into changing heads and cam, there really is no difference in the car itself. RobZ went 9.6x with a 346.
I'd love to put that engine in my car, with the correct converter, and see what it would do.

Ok thanks Pete , I do value your opinion though 👍

the list may have morphed from the LS tech list and I'm not sure THEY would approve but my problem with their list is they also run better rears, we are all IRS.
adding better pistons, rings, rods etc., can certainly add horsepower and I have no problem "IF" I do go faster would have no problem adding an asterisk that I used race parts. or something to that nature because I think the spirit originally may have been "stock bottom parts"
I look at the current list and see hardly any of the folks are even active:
2) 10.600 @ 124.16 - JON CONA - Retired (not active)
3) 10.71x @ 127.32 - sixspdvet - RIP
4) 10.752 @ 126.91 - paint it black vette - RIP and that car has a 382 in it
5)10.784 @ 132.57 - JIMS SVT - ?
6) 10.819 @ 130.08 - Fartpipe - car gone
7) 10.930 @ 123.11 - algZO6 - different setup
8) 10.991 @ 123.72 - RonSSNova
9) 10.997 @ 125.54 - PRE-Z06 - ?
10) 11.05x @ 120.50 - FACE - ?
Point is, there seems to be a lack of people anymore even trying to modify and see how fast a C5 can go. IMHO the LS1/6 can compete with the newer power plants. Interest is mostly the C7 today and C-6.
I feel I would have beat my 10.22 by recently just picking up over 20 RWHP (mustang dyno) but before getting to run the 1/4 again the motor went...
Thoughts are welcome

Im good with the asterisk too so are you gone to update the list and remove some ?Ive been trying to get in the top ten I just made some more changes and hopefully next week make a few passes to get it in the 10's and in the top ten. And I agree the ls1/6 can compete with the newer power plants.
That works for me :-)

Funny where your standing falls into when you realize who is still trying go go fast with a 346 H/C car
makes life a bit interesting.

I dunno, I wanna sit on top of the C5 manual trans list.....and I am shooting for 8.90 - 9.0 once I get the car back together. But that will also help with name recognition for when I open my shop after I retire this fall and move back home.
