You know i've never seen your condition in a mazda guy. I do fleet maintanance for a living and all we work on is Fords so we see a lot of blue oval syndrome. Now i'm here to tell you there is hope! All you must do is open your phone book and call your local chevy dealer. tell them your problem and they will be more than happy to assist you in fixing your defect.

btw the interior looks good i dont care for the loud colors but the workmanship is excelent

 

Here in Canada Fleet is a fast acting ennema and I see you need a good to fleets...as your full of it...All joking aside
Actually the truth is I am not loyal to Ford per say but the rear distributor and my custom bell house would not match.
I have converted a B2200 witha small block and knew of that problem in advance.

B2900

 

Ive known of this problem also and my solution to it was to find a 93-98c. GM F Body with a LT-1 and a T56 so as to retain the standard trans and no dist so wheres the prob. now mind you a 2-3 inch body lift does help the motor and trans fit much better and you dont have to beat the living shi out of your firewall. the next idea is to do an lt4 conversion oh and it get about 32- 34 mpg on the high way better than any b22 or 26 ever did
