here is some more injun raceing history . ever heard of the Super Duty raceing program of the 60,s(60/63) ranging from the 389 to 421 pontiac engines that SMACHED chevy ford mopar in sutch a big way,on EVEY field that GM under presure (ecscuse) from the govermend about becoming to big, puled the plug out of pontiac,s raceing departmend up till this presend day!!!! chevy was seen as the poor mans raceing horshe(not a degrading coment) and wat ever happen HAD TO STAY the biggest selling brand within the GM famely time over again Pontiac with a mutch smaller buget proved to be inovated enoughf to stay iven and sometimes ahead,witch proved the ecselence of the engeneers at PMD (SD 455program and beter engine disighn in general over chevy) Pontiac was not alowed in the mid 60s to eurly 70,s to stick a bigger engine then the 400 in its Firebirds and GTO,s (you ever saw a 455 chevelle beat a 400 GTO on the streets dont think so) while the 421/428 and the 455 where availeble. Pontiac in the Transam raceing series was forced to drive with chevy engines, when pontiac finally had the unbeliveble RAM AIR V engine in the later stages of developmend to enter the game again GM puled the plug again!!!!(go figure) the tottal dominance and shock wave of the SD raceing program of the eurly 60,s had GM and al the cooperatif brands leak fluid till today , resend history has it done again .in GM saying whe only need 1 brand in NASCAR racing lets pull the pontiac plug again ..last but not least the only rezen that GM puled the plugs on the other Motor divisions in the late 70,s and go on with 1 engine fits al stratergy and choose the chevy smal block engine had nothing to do with quality ore engenering ecselense, but with COSTS the sbc was is cheap to build and that was the end of pontiac oldsmobile and buick,s motor divisions. a dam shame if you ask me. GM
