For your inquiry, here is what I found:


302-290 Z28 315 rating
427-425hp L72 435 rating
427-420hp L88/ZL1 480 rating
302-290hp Boss 330 rating
340-275hp MoPar 310 rating
426-425hp Street Hemi 480 rating
455-370hp Olds W30 380 rating
350-255hp 1969 Chevrolet 265 rating
400-370 1969 Pontiac RAIV 380 rating


Your '62 Pontiac 421-405hp combination was listed with and without the lightweight components, which we do not have in the current Class Guide. In 1969, C/S was an 8.50 break; in 1970, C/S was an 8.00 break. The lightweight component car would have made C/S easily @ 8.57 factor.


Odd items:
1) I cannot find a listing for the '68 Dart SS Hemi car.
2) The ZL1 '69 Corvette is in the guide
3) The LS7 '70 Corvette is in the guide
