Axle retention device is a positive lock to keep the axle from separating from the differential like a C-clip eliminator for a GM 10 or 12 bolt. This is the portion of the rule I was referring too. "" Cars running 10.99 (*6.99) or quicker that weigh more than 2,000 pounds (907 kg) with independent rear suspension must have swing axle differential replaced with conventional differential housing assembly. ""

That is a bad azz Z no doubt. But how is he getting past NHRA tech? Or is he just doing test N tunes at none NHRA events? NHRA rule 2.3 REAREND After market axles and axle-retention device mandatory on any car running 10.99 (*6.99) or quicker and any car with locked differential. Cars running 10.99 (*6.99) or quicker that weigh more than 2,000 pounds (907 kg) with independent rear suspension must have swing axle differential replaced with conventional differential housing assembly.

Hey Stu I don't know if I can make the deal on the 28th? But I will be at Montgomary motorsports park on the 14th & 15th of may. If you get a chance stop by.

What kind of ET are you turning with that MPH? JB...158 is turning it on in the 1/4

I have not had a turbo but My 383 chevy V8 works good for me. Although I am sure there are faster ones around I have yet to run into one at any of dragstrips that I go to. I do not do much 1/4 mile racing mostly all 1/8th mile but I do go somewhere almost every weekend threw out the summer months. The last 1/4 mile pass I made was a 9.53 with a 1/8th mile time of 6.07 But now that the weather has been getting a little cooler I have been putting together a string of 6.02's the last few weeks. I am bracket racing and trying more for consistency than just ET so I am leaving the line at 3800 rpm to help hook on a less than perfect track. I believe that if I was to turn the leave RPM up to 4500 5.90's in the 1/8th would be no problem. Add a little N20 and it would really be a wild ride.

Thanks I will check them out.

Where is the best place to find a lower air dam like this one? I like that To me mine looks like crap in the front end.

Felpro 1003 is .039 thick but will only go up to a 4.155 bore. The 1004 is .041 thick and will go larger than 4.155 (This is what I recomend) Also there is the 1044 that is .051 thick. I run the 1003 on my 355 and the 1004 on my 377

Cool. I will. If you are ever up at Atlanta Dragway or MMP or Silver Dollar on a race day and see the JBS Racing trailer stop by. We are at a track somewhere about every weekend.

I wish I had known about it. We would have Def been there. Is there a Schedule of events? We Go to Silver Dollar a few times a year, when we have a open weekend. I would like to come to one of them.
