Next year for sure will be competing, this year if possible i will trailer it out and see. What is the index for mod N/A and any restrictions? I'm sitting with a S60, twin plate clutch, stage 4 t56, 10pt cage, and this engine i'm building. and only weigh in at 3085lbs with my last engine (without me) so 3300 with me in it roughly. Any fuel limitations?

btw your car sounds good, which cam do you have in there?
Mod N/A is fairly open to whatever you want to do. There is no index. Run as fast as you can. It's heads up on a .400 pro-tree. The weight limit is 3075lbs WITH driver. Any race fuel you want to run, and aftermarket pcm. To be competitive you should be well into the 10's. Last years winner was running 10.29-10.40, but keep in mind it was 100 degrees out.

The full rules are right here:

LTX Modified N/A
Limited to quickest 32 qualifiers. Must have LT1-based engine. No power adders permitted. Heads must retain the factory 23 deg valve angle. Trick Flow 21 deg. heads permitted (PN TFS-30400008-M54). Converted intakes, stock and sheet metal permitted. 30" maximum height and 10" maximum tread width for bias-ply tires. W's limited to 28". 29.5 x 10.5 bias-ply permitted with 150 lb. weight penalty. Drag radials permitted. Non-stock style suspension permitted. Mini-tubbing permitted. Wheelie bars not permitted. Aftermarket EFI, LS1 PCM and carburetors permitted. Any GM transmission allowed. Lexan windshields not permitted. Independent rear suspension receives weight break of 200 lbs. Manual transmission receives weight break of 100 lbs. Minimum race-weight limit 3,075 lbs. Car and driver must meet NHRA certifications for the time the car is running.
