Merv, I know that there was at least one very succesful year as you mention, but could only guess at around 76 thru 78 I think.
As for engine refresh that was only each off season and I dont remember any major failures other than the original 289 Hi Po and it was run straight as imported from the Shelby. IIRC the 351, it broke a rocker stud at the NZ Champs in NI as TC got his thumb burnt holding it over the stud hole in the head/water jacket while they searched for a replacement.
Much more time was spent replacing bent suspension & replacing side panels/paint etc. We were always looking to improve suspension/traction etc & PJW was always fitting new rubber, like most motorsport its the whole package rather than just HP, he found that out in hurry with first meets in the Firebird.
