can astock1969 camaro beat astock 1972 mustang mach 1 with a 351 cleveland

 

Here are the engines for a camaro.
230ci/140HP L6 1BC - non-SS
250ci/155HP L6 1BC - non-SS
302ci/290HP V8 4BC - Z-28 only (HP underrated!)
307ci/200HP V8 2BC - non-SS, 1969 only
327ci/210HP V8 2BC - non-SS, eliminated during 1969
327ci/275HP V8 4BC - non-SS, 1967-68 only
350ci/250HP V8 2BC - non-SS, 1969 only
350ci/255HP V8 4BC - non-SS, regular fuel, 1969 only
350ci/295HP V8 4BC - SS only, rated 300HP in 1969
396ci/325HP V8 4BC - SS only, Q-Jet
396ci/350HP V8 4BC - SS only, Q-Jet
396ci/375HP V8 4BC - SS only, Holley
396ci/375HP V8 4BC - SS only, Holley, Al head
427ci/425HP V8 4BC - COPO 9561, cast iron
427ci/430HP V8 4BC - COPO 9560, Al block/heads

So it really depends on what engine that camaro has under the hood.

 

the camaro is lighter too but depends on the drivers tho.

 

Sorry but threads like this are chocked full of too many variables. Engines, transmissions, gears, drivers , surface , tires , weather conditions , hell even the phase of the moon can affect any vehicles performance.

For example a 69 Camaro with the ZL-1 option will surely destroy any 302 Mustang as factory equipped, assuming of course that traction , drivers, road surfaceetc ... areequal. On the other hand if you were to line that same ZL-1 up beside a Boss 429 or Boss 302 or even a 428 SCJ... you'd have a hell of a race once you got past the tire frying exhibition.

With all of these things in mind ... this question is unanswerable.
