383 TTI Headers & exhaust Clearance issues
« on: February 14, 2012 - 01:45:08 PM »
So I bought the TTI Headers & exhaust kit(1 7/8,  3") for my 1970 383 4speed cuda. I did not buy the schumacher creative Service engine mounts. I have been installing the exhaust on & off the last month now trying to get it to clear the first Ujoint better. Take a look at the pics. Passanger side is away from joint & I am happy with. The drivers side looks way to close to me. Anyone know how to deal with this issue. I did measure center of crankshaft to each frame rail. the difference was 14 1/2" on pass & 17 1/2" on drivers side. In TTI specs it says a 2 1/2" difference. Center of crankshaft to top of k-frame is 5-1/4", which shows as correct. I do not know if this would make the difference I need or not. I have the #12 K-Frame with the 1965 engine Block also. Any help would be great. I tried spinning header adapter every way that would mate up to header with no luck.

Also, I was wondering what year engine mount setup would I need with this setup. Thanks

Has anyone had any clearance issues with the TTI system. I think my problem is the exhaust adapter to connect to header. The way its bent does not seem to line up correctly.  :crazy:

it is obviously off either due to the mounts or the bends , you measurements were off I believe .
 not sure how to help you though , the pipes are stamped L or R so I assume you have the correct parts in the right place ?

Left on drivers & Right on pass. Needs to be 2 1/2" difference from side to side. I got 17 1/2" drivers & 14 1/2" pass, measured to frame rail from crank center. Needs to move towards drivers side 1/2". Up/Down was right on the money 5 1/4". Is there any way to adjust the original style mounts.

other than replacing them ? Not really , sounds like 1 may have been replaced with a cheap one that was too fat pushing the engine over too far .

I made 1/8" shims for my motor mounts so I could get the headers in the best position possible for clearance purposes. I have a 440/727.
