Limited information here, but I'll take a SWAG at it.

The convertor looks tight for racing. The camshaft looks small, very small.

What I suggest is to go to my site. The address is in my signature. Click on "CI Build Sheets". There are (3) versions there. You need the standard build sheet. Complete it and e-mail it to me as an attachment. There are directions there on how to complete the process. This will allow me to look over your information and get a feel for what you need.

Thanks.
