"Actual Match Race" 1969 440 'Cuda vs 1973 Firebird Formula 'SD-455'
Mr. Rusty Rod,
I'm not wrong on the weight.
I posted 'Shipping Weight' {#3470 lbs.} based upon NHRA Classification Specs.....
The 1973 Pontiac 'Formula SD-455' was-and-is classed in NHRA E/SA.
{10.00 - 10.49 Wt/Hp}
Though the SD-455 is 'Advertised' listed at 290 HP, Pontiac re-upped it to 310 HP,
and the NHRA re-factored it to 345 HP.
---------------------------------------------------------------------------------------------------------------
As for who was quicker in the 'Quarter-Mile' {September 1976}
The 1970 Buick GS-455 held the 'C/SA' National Record......................11.93 @ 112.89 MPH
The 1973 Firebird Trans Am 'SD-455' held the 'E/SA' National Record....11.89 @ 112.50 MPH
Note; The 1973 Firebird 'Formula SD-455' is about 100 lbs. lighter than the 1973 Trans Am....
So which car is quicker in the 'Quarter-Mile'....... And Handling, lets not go there...........
That doesn't look like no 'Heavy Pig' to me.........
