I am thinking about adding a blow proof housing as I swap in a 426 hemi into my Road Runner. Any recommendations? I am running a McLeod dual disc clutch set up with 130 tooth flywheel with Hemi fourspeed. I also plan on using TTI headers. I know Lakewood makes one. Is there a particular model or part number I need? I have read on posts here before about having to grind on flange to clear clutch linkage. Any other pitfalls I may run into? Thanks.
