Hi, my name is Francisco, I'm 17 years old, I'm writing since Mexico. Here is my problem: I have an Oldsmobile Vista Cruiser '75 (but my grandfather says is a Cutlass Supreme Cruiser, I don't know if this model really exist), well, the engine is a 455 (396021Fa), the question is:

Which is difference between the 396021F and the 396021Fa?

I hope you can help me, I really love this car, Olds Engines are the best of the best.

Regards from Mexico

Hola tolesco,

Bienvenido a TOC

'64-'77 Cutlass Wagons were Vista Cruisers. There were no Cutlass Cruisers until '78.

Your 396021Fa is a '72-'76 455 Olds, while 396021F is '68-'71 455 Olds.

Recuerdos, Norm

Thanks man, I listen that 396021F is better than 396021Fa, is it really true?, which is better?

Well, the problem about the name is because I found an etiquette inside the car and this says:

Cutlass Supreme Cruiser - Vista Cruiser

What can be?

De onde en mexico es usted? Mi familia es de Michoacan, y del D.F.

Saludos. Pues entonces somos paisanos, soy michoacano, vivo en un pueblo llamado Pajacuarán, cerca de Sahuayo y Jiquilpan. Como ve, aqui ando gastando mis ahorros para hechar a andar esta Vista Cruiser 75, el motor esta en buenas condiciones, si es posible pienso cambiarle el arbol de levas, los anillos y nuevos headers para que corra mejor, y ya solo le faltaria una buena pintada. Quien sabe, tal ves de aqui a unos 5 años lo logro (dependiendo de mis ingresos). Saludos desde México.

Later blocks were a little lighter in weight, and the engines came with lower compression, but they are no better, or worse, than the earlier block.


Etiquette?
