Default what are the exact rules for bolt on record?

im going after this record and need to know the exact rules..tom and shon have already told me good luck with it..i am using a carb and lt4 intake..before i get **** for this..a carb is just like swapping throttle bodys and a intake is more of a bolt on then pulling your heads off and swaping springs,rockers and push rods.

here are my questions,tom has already told me a rebuild is out..so im doing this with a 151k long block..lol

when i pull the heads can i swap to a thinner gasket like used on a caprice?..i read that the rules summed up is you basicly use a lt1 long block..so this is why i ask,

can i swap lifters seeing pushrods and rockers can be swaped along with springs?

can i swap cams to a later camaro lt1 cam seeing i have a 94 and i know the later yrs are diffrent

can i back cut the valves? When i have the heads apart?

I thought there was a post or thread somewhere that mentioned the "rules". You talked to those two and they didn't mention it? Maybe I'm wrong or it was deleted.
I don't think backcut valves is going to fly, but what do I know. I thought allowing a carb was pushing it.

Spring and rocker swap is allowed. Removing the head or intake should disqualify you.

Intake and carb would get away from a bolt on motor. How can it be considered a "stock" bolt on when you no longer use the stock computer to tune the fuel?

A carb and manifold is alot closer to a bolton than pulling the valve covers and doing springs/rockers. The LT1 bolton rules should the be same as the LS1 rules IMO. With that said I'm just not exactly sure what the point of building a car for an internet fantasy class is anyway.

im only doing it because im turning my car into a 275 stock suspension car in the long run so pretty much i figured i will go for this while im building the real motor..after all the intake and carb will be the only thing i cant toss on my gen 1 engine once done..

and i fully agree a intake has always been called a bolt on..ask any real old timer what is more a bolt on..springs and rocker or a carb intake..lol all will tell you intake...as for swaping springs with out pulling heads..um that will be a pain in the dick with these cars..plus i dont have a air compressor here yet..so mine have to come off..and yall the back cutting valves would be pushing it i think but you dont know till you ask.

I have no problem with a modified stock "style" intake. Even in Modified NA in the ltx shootout in an almost unlimited all motor class if you convert to a carb you get a weight penalty. Carbs/converted intakes aren't even allowed in extrem NA at all. Its all just internet records anyway. Build the car the way you want it and enjoy it and not worry about it. No matter what you do when you claim one of these "records" someone will just bitch about something you did and how thats "not a true bolt on". Enjoy your car.

ask them if converting to EFI is a bolt on.

It's up to you to decide if it's O.K.! After all FI is the best because it will only generate full power if conditions are right! Otherwise you will mess the motor up a lot sooner....

yes i do speak it...i dont have time to spell check though when im posting from my phone seeing it logs me out after a certian time is used..thats why my first post is in 2 replys..

yes most think converting to efi is a bolt on..intake and rails bolt on to the engine.

i want the record so i do want to fallow the rules and a carb engine setup right will make more power..why do you think so many drag cars that run n/a or on juice use carbs..

if you want to run a carb on a bolt on only car you go right ahead. a ported intake will work a lot better though

im sure a ported or port match intake would make more power..but from what i under stand is a ported intakes are a no no..ill pm tom tomarrow on a diffrenet site and see what he says for rules seeing after all he is the current record holder...

p.s you efi guys..billyman of r.p.m told me to use a 93 intake seeing they flow the best..not surr if its well known..just figured i would transfer over of what he told me to yall.

lol yep..record aint that easy..like billyman told me on the other site i talked to him on..its not really a bolt on record but more of a pure stock style of class with the rules..way i look at it is it gives me a chance to still have fun running my car and testing while the real engine is being done....once the real motor is done im looking for low 5s in the 1/8th on 275 radials.

They don't run EFI, because the rules do not allow it. It would add a huge increase in costs that only a few teams could afford to pay.
