that would be an all tubing chassis like a pro. mod. or funny car chassis, i think.

It means you have to use the stock-type front frame rails. No tube chassis.

So if I box the frame I will be ok?

I'd ask some body that has been through tech. before, but I would think they would let you do that. you must be talking 1/8 mile.

Ya,I have a 3 tracks with 45 minutes from me ,and about 3 more within 2-2.5 hours from me .Theres is only one 1/4 mile track thats 1 hour away.


I am still questioning this boxing of the frame maybe Tech can help out.Will in the street class everything should pretty much bolt in its stock locations.Well If I box the entire mid section(just behindthe front crossmember ,up to the rear end) then the trans support ,and the main cross member will have to be welded in.

If I weld in sections in for boxing then I can bolt the crossmembers in to the frame.

Anyways my question is do I have to do it in sections ,or can I run a 8 foot long piece and weld the crossmembers in for the 10.5 street class?Anyone here familiar with this?

I'm pretty sure the double frame rail refers to a full-on Pro Mod SFI 25.2 tube frame, so don't worry about it.

You can box the frame rails partially or all the way to the back, but my question would be.....why would you want to?

Do you have any idea how much money it will cost you to be competitive in a 10.5 Outlaw class?

I have set my sights a little lower,something like Ez Street.I want some thing I can drive on nice days.Besides the race track.

I still don't understand. This is not a car you can drive on the street and then go to the racetrack and be competitive with. Have you seen the rules? It'll cost $30,000 to be competitive 'cause these things run in the 9's.

Reality really bites!!! The last 9.90 car we ran and were competitive in was in the early 90's, had a bit over 20K in the car......

Bracket racing locally is a lot cheaper. Once your car meets the sanctioning bodies safety requirements, you can build the car to run as fast as you can afford to go!!! I would love to dig my old GTA out of the barn and run NHRA Super Stock class---just don't have the $25k to $30K it would take to make the car run on index..... Like I said, reality bites!!!!

Consistency in a car is to me far more crucial then low et's.... If you can get the car and the driver to run the same times in the same RT/dial-in package round after round you can be a winner against the mega buck cars......

Well what I am looking at is not EZ Street,what I meant was True street.I am building my truck, should take about another two years and more money than my wife would like for me to spend on this project I have decided to go with smaller cubic inches just to be somewhat comfortable on the street.I still want to drive it to the local drive in.I am thinking some where around 700-800 horses.I am asking these questions also to see where I can best fit in,with my needs.Bracket racing is just plain BOARING.I don't want to build something that is not legal on the track. I am not planing on coming in and taking over the field,but don't want to take away something from the frame set up that will ruin my chances from going faster a year or two down the line. The fun in it for me is getting in and learning more about what it is going to take for me to go faster.

Double Frame Rail does indeed refer to a tube chassis race car. More specifically when one speaks of double frame rail it refers to the pipe running down the middle of the car (either side of the driveshaft, main frame rails) and a double frame rail cars has sets of rails one on top of each other spaced 6"-8" apart. Oh yeah, everyone has their own opinion, but bracket racing isn't boring if you're good at it. Unless you call running for $10,000+ and racing decided by .000-.010 boring. Hope this answers your question.
