Could you locate and post a few E.T.'s and 1/4 mile times for the 68 HO, 69 HO and 69 Trans Am? Of course not solid proofs, but ideally.
From what I have read in the past, according to Hot Rod and Car Craft (and from some GM paliterature) the 68 HO was faster than the others. I have yet to locate and RAI or II independant tests of non modified cars (Royal/Myrtle)
1968 Firebird 13.79@106 400 HO 335 four-speed HotRod 3/68 1970 Trans Am 13.90@102 400 RA 345 four-speed 3.91 HotRod 2/70
I actually wrote a book (unpublished) on Pontiac road tests, about 180 pages worth. Back in 1999, I had a very primitive web page (it's still out there somewhere) with some summaries of a few of the more noteworthy road tests. The problem with original road tests is that there was no consistency between them. Weather conditions, driver ability, etc. all contributed to wildly varying times. Sometimes the same car was tested by 2 different magazines, and et's varied by half a second.
