My 6.1 retrofit thread

This pic shows the TTI block off plate partially attached - its a perfect fit and uses O rings to seal to the boss.




The TTI engine mount adapter requires a small amount of trimming to clear the plate - not sure how TTI could have missed this pretty basic issue.....:(


Because the block off plate was designed by someone else (not TTI) after the fact, and the mount was probably never modified to accomodate this. The original TTI design for a block off plate also did not include the O-rings and would have probably leaked. One of the first customers to get a TTI block off plate for his '67 A-body Barracuda Convertible had an engineer friend of his design a block off plate that included the O-rings. He e-mailed the drawing to TTI and they sent him the first article free.

True story!
