Hi all,

I'm getting ready to do an engine swap, and I figure this is the time to swap converters if needed.

The car is a 1966 Bonneville. It is currently a 389/4bbl, and it is really tired. It's a TH400, and it had 2.56:1 gears, but I'm in the finishing stages of installing a new rear axle with a limited slip diff and 3.08:1 gears (I know, not great, but 65-70 Pontiac B body rear ends are not exactly common). Curb weight should be just over 4000 lbs, with me in the driver seat call it 4250. Tires are currently 225/70R15, probably can't go much bigger without getting custom offset wheels.

The new engine is a 400 with the following specs:

1970 XH code block, .030" over, not zero decked
L2262F30 forged pistons on reconditioned stock rods with ARP bolts
13 heads, rebuilt with new valves and guides
The cam is a Wolverine Blue Racer, 224/234 @ 0.050, .465/.488 lift, 112 LSA.
in a previous thread I think we determined the compression ratio should be around 9.5:1.
Edelbrock Performer RPM intake manifold (I have a plain Performer and a stock cast iron 4 barrel manifold too if either of those would work better)
Exhaust will be B body Ram Air manifolds from RARE with a 2.5" exhaust with X pipe.

The car will primarily be driven on the street, but I will probably take it to the drag strip a couple times a summer. I know it's not going to be an eye popping fast car. It's heavy and my gear ratio is not all that favorable.

Given all of this, what converter do you guys recommend?

Thanks!
