Pontiac 400 Front Cover interchange

Is it possible to use a '67 400 front cover AND balancer on a '73 440?
I know the bolt patterns on the balancer are different (6 vs 4) but I want to transplant the whole assembly.
I am building a '29 A coupe with a 400 so it's a tight squeeze.
I would gain some radiator and crossmember clearance and that would mean a lot less fooling around with motor and trans mounts.

Pontiac front cover

Not sure what you are talking about, Pontiac never built a 440. 440 is a Chrysler Big Block.

Pontiac had a 421 engine till about 1966 & a 455 engine in 1973 ...as I remember. Any one of these ring a bell?

If that was just a typing error and you meant '73 400 the answer is yes. You need to use everything from the front of the '67, such as brackets, spacers, etc.

Fat fingers

Thanks guys,
Yeah, I had a case of fat fingers when I typed 440 I meant 400.
I thought every thing would swap but it's been a while since I played with these motors.
I grew up (?) in the "Golden Era" '60 - '72 and I was fortunate to have had a cousin who was a Pontiac dealer. I worked there for a while and had a few old Pontiacs. My favorite was a '61 Catalina Bubble Top with Tri-Power and 8 lugs. We split the floor and put a 4 speed Hydramatic from a Bonneville in it. The factory rep said it couldn't be done. We used Permanent Anti-freeze cans to fill in the gaps. The Permanent ones last longer.

I guess it's been a while! Anifreeze comes in plastic jugs, now.
