tti header oil pan fitment

Thanks for the info I know personally of a guy that has a 408 build and his TTI headers did not fit the pro touring oil pan ( however I do know that the 340 oil pan is different from a 360 oil pan) however I don't know the exact dimensions of the difference . I really wanted to pull the trigger on the pro and he was running a 727 and I'm running a 904 built by cope the 904 being smaller I thought maybe it would fit with more clearances 727 but then again I also don't know touring pan and the TTI headers . I do have a set of dug headers but I'm not even sure if they will clear the pro touring oil pan and they're also much smaller header than the 1 7/8 TTI header I'll give the thread a good read thanks for the info :)
