You will have to relocate the cross member, replace the driveshaft, pound the hell out of the transmission tunnel for more room, and install a Bonneville carpet… among other thing, but worth it.

Banshee,
Are you sure of this? Bonneville carpet? I have all of these cars in my wrecking yard and I cannot see a difference. I have put 400 thms in 3 '61-'64 Pontiacs now with no floor pounding. Have you done this personally? All the ones I have done, floor interference has not been a problem. I think the hydro shouldn't have problems with the floor. Anyone else? Curious as to why the floor has been an issue for some but, not for me. I drive my '61 everyday with 400thm and no floor problems. Anyone else besides me drive a '61 everyday?

FWIW- I am in process of putting a 73 455 long tail turbo 400 in a 62 Cat. I sat it all in and bolted down the motor mounts. When I raised the tranny end into the tunnel, the tunnel is (at the least) about 3/4" too narrow on each side for a distance of about 6" in length. This close area is about "halfway" back on the tranny. I marked where I needed to enlarge the tunnel. Then, winter came.
P.S. The tranny dipstick tube is too close to the firewall area right at the point where the plane of the firewall/floorboard intersects with the start of the tunnel's "bellhousing" area. Looks like that area will need about 1/2" of clearance made. When I resume operations I am going to photograph all this area before and after so that I may be able to spare somebody the headaches of the in-and-out of their motors when they are tryting to figure out how it will fit. ( This will also relieve a lot of tensions with your wife who can never remember which chain on the hoist is up and which is down, not to mention educating her on use of a hoisting load equalizer.) |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
