I had previously posted about the TFS Track Heat single 4V intakes for use with the Standard adapter. I spoke with the TFS tech dept and the 51600111 and 51600113 manifolds are actually the same, except the 113 is applicable to Clevors and even though they are typically for 9.2" deck blocks he thought the 113 manifold might be wider (?). The picture of the 51600111 is actually a drawing giving the illusion of slightly smaller OD runners.
I ordered the 51600111 from Summit, I've received it and I believe it will be about the easiest port match ever to the adapter. The runners are larger than the Ed Torker, the TFS casting is really nice and the ports are really pretty too. It is tall though.
After I mod the manifold to fit the adapter, I'll know way more. No I don't work for TFS, Rick Wanner
