I just heard from a buddy that got back from the Boone Nationals, of some possible rule changes for stockcars next year?
1. The use of 89-newer bodies on metric
2. Stock firewall can be eliminated
and fabricated aluminum ones can be
3. Fabricated tubular bumper may be used,
similar to modified bumpers?

He thought there was possibly some more, but that was all he could remember. Has anyone else heard of these or any others?
Just curious... like to start planning for next year...

I saw the "Jet" '05 imca stock car at nationals it had a early 90s regal body and the firewall cut out down to the seam, looked like the floor pans were off a metric, didn't notice tube bumpers on it though, but it wouldn't suprise me

I called a chassis fabricator last night and he confirmed all three of those... per imca...firewall included, down to the seam of the firewall and floor pan (steel, not aluminum)...I asked him why the firewall and he said because people wern't getting all the hole covered and decided that that would be easier I guess. As far as the bumper, he said just the front one could be tubular. He had also heard about 500 cfm carbs but nothing official on that yet.

hey racer17j, If I was to put new body on a current car that I was running a 86 cutlass body on, is it likly that the new body would fit over the cage, or are they too different?
- How do you attach the body?
- Is any advantage, weight, weight
percentage, ect. to running the newer
- What about the panels are they all steel
or are some alum?
- what about wheel base? same as the older

sorry about all the questions? just curious, Id like to try a newer body as long as its worth it and not alot of extra work... thanks for the help....

newer bodies are shorter, narrower, and the roofs are also smaller.. if your car is close to the minimum on cage rules one would fit.

hood clearance is the place to start when installing one, not the roof.

thanks JohnG... when you start with the hood is that basicly to set the height of the body from that? I woundered if we'd have hood clearence problems. Like with the front radiator supports and aircleaner.

yes most imca cages are low enough to allow you to really drop the roof, but if you must keep it stock appearing you then wont clear the air cleaner..

Its going to be a tight fit anyways, because the hoods drop so low in the front.

Ive used 82 and up camaro bodies before, but used aftermarket fenders, hood, nose, I tried to then fit oem on for a diff track and it wasnt going to happen..

They should just allow performance bodies aftermarket stock appearing late model bodies, they are cheaper than junk yard panels, and its easiet to order them ready to install etc.

This would separate the stocks from the hobbies, as it is now they look the same from the stands.

Any idea when IMCA will update their rules.

All this rumour stuff is hard to wade through.

When Mark Elliott (Terminator) switched his own car over to 90's GrandPrix, he told me it was 200 lbs heavier than the 80's body he got rid of.

IMCA rules are always printed in the IMCA paper that comes out just before the first of December. Around Thanksgiving.

You are on the right track. The bodies are going to have to be OEM and fit and look like OEM. I wouldn't count on complete aftermarket bodies anytime soon.

Good luck,
