rpfan Posted July 22, 2010 Report Share Posted July 22, 2010 Will a front running Thunder stock from THR run up front at I37 with minimal changes and would it be legal?? Ready to bring it I do believe. Link to comment Share on other sites More sharing options...
Hansen99 Posted July 22, 2010 Report Share Posted July 22, 2010 Dont do it just bring it to Thunder hill and see if you can keep it up front it will cost an arm and three legs to put it on dirt might as well just bring it to THR Link to comment Share on other sites More sharing options...
abrungot Posted July 22, 2010 Report Share Posted July 22, 2010 Sure would be a shame... Reading the Purestock rules... here are the rules i see that "could" be of issue: 3.6a: No aluminum intakes allowed. 3.8: Stock cam for type and year of engine. 3.8a: Engine must pull 15 inches of vacuum @1000 rpm. NO EXCEPTIONS. 3.8b: Hydraulic lift only. No solid lift cams allowed. 3.9a: No exhaust flow devices allowed such as cross piece of H- pipes. 3.9b: No high performance exhaust manifold of any type allowed. 3.9c: No Ram Horn exhaust manifold. 4.2: Stock rear end *(not sure if you can use a 9" Ford in Chevy) Link to comment Share on other sites More sharing options...

TTR73 Posted July 23, 2010 Report Share Posted July 23, 2010 lower the air pressure and go racing you will run up front we did it at the end of the race season it was fun!!! They will only let you run a few races there before you have to change the stuff on the car. Link to comment Share on other sites More sharing options...

TTR73 Posted July 25, 2010 Report Share Posted July 25, 2010 We only went for one race at the end of last season. So we never made the changes... All we did was lower the tire pressure on the 970's and went with it you would think you wouldnt get grip with those but you do! Link to comment Share on other sites More sharing options...
