There's a nice thread by "Javelin GT" on this AMC forum
showing some nice photos midway down of some Javelins from the '69 Wolverine Trans-Am.
This particular photo posted by Javelin GT shows the hood up and reveals the taller manifold and aircleaner used by the Javelin team
at that particular race. It is obvious that the blistered hood is necessary for clearance.
Also, there is a nice short interview with Ronnie Kaplan on tajavelin.com
where he describes the special engine used by the Javelin team
to start the '69 season. This special engine based on the 343 block rather than the 290 and with a lower deck height, taller manifold,
dominator carbs, etc is the reason why they were so fast at that Michigan race. Sadly for the AMC team, somebody didn't properly
homolgate that engine (fill out the proper paperwork) so it couldn't be used for the rest of the season.
