Ive read that about the hoosiers also, i started to buy a set but wanted to go with what i knew worked for me. Did not want to have problems at the first race this year but that happened anyway lol.

Bought me a valve spring pressure tester and seen how bad my springs are. All the exhaust springs are good but the intake springs range from 58-65 on the seat to 200-207 open. Hope this is causing my problem.
What do you guys think if i put a new set of stock springs in, would you guys still consider that stock internal. I need new rings or a piston too lol won't be changing that tho.

I ran the MT ET Drag 28 x 10.5's.... One of the reasons I think my shitbox ran so well is because of the tire/gear combo. When you run the taller tire, there is more sidewall to absorb the initial hit, the sidewall wrinkles and dampens the shock to tread / track.
When I tried the 28" tall tires the first time, I did it with 4.10 gears... And every time I launched the RPM would drop too low and it would bog badly. I tried 4.30's and it got better, but just wasnt solved. 4.56's and the shock to the tires was less, it would bite, and the RPM's wouldnt drop into bog.
After about 20-25 runs the sidewall would "loosen" up, and wrinkled too easy, causing them to absorb less shock which got transfered to the track resulting in spin.

Yup, I've got LS6 springs and valves. I bent all the stock intake valves last summer and had a set of 243's that I robbed the stuff off of. I'm not on the list because I've never submitted a time slip or even posted in that thread. I just have it in my signature.

Yeah the idea is completely stock, original parts. But I don't agree with the spring thing either. With cars this old you should at least be able to get some fresh springs when you run them this hard. Either way, you've got one of the fastest si M6's, different springs alone aren't going to change that.

I ordered a new set of stock springs, after seeing one sit at 58 pounds on the seat makes me worry alot. I guess the only reason i have not slamed a valve into a piston is the fact that its a stock cam.
I agree with you guys on the springs, i do think it should stay with the stock spring specs but i don't think an ls6 spring or anything with more pressure would make more power at all, if anything i would think more pressure would make a little less power.
