Well for the rulles you can go to there sights to get the books and information.
. I dont have the ihra book and you kinda need an inturpetor to read the nhra book. It is a good place to start. Also the nhra book does have a basic plan for a car. If you bild your car to the top fuel specs you wont have any problem geting it surtified to run. Just stay with in there standards. Theese standards are so far and above whe we need to be safe it is rediculos but if you want to play in there sand box you play by there rules.
THe car that I just bilt wont stant up to there specks. I used .095 dom miled stell tube. they want .118 wall. I usto run circle track and the 090 is strongenouph to save me at 120 mph with 3300lbs and 20 other idiots trying to drive threw me so it is way stronget they I need for this 600lb car. But they dont car about weight or total mass. THey have rules for that 1000 lb chunck of iron that is trying to run you over.
I am runing at a couple of outlaw tracks so they dont car . It also hepled me to find out the amount of material I will need to bild the better car. I also bilt my gigs so I can bild the next one. As soon as Ican aford a Tig I will bild a cromemolly chasie that can be surtified. If you would like my meshurments I can putsomthing together for you. Hope that this helps. Dan -=-=-
