one thing you may want to look into while still in fabrication stage is the 25.3 spec. the couple extra bars will allow you to cert. to 6.0 instead of the 7.50 with the 25.5. you may never use it but is nice to have if you ever do upgrade down the line. also one mistake i made is checking for clearance on the dash bar (same as yours) the stock cluster will not fit




Kind of thought about 25.3 but with my budget it will never go 6's. Going to be using aftermarker gauges. Stock ones are to dang hard to see at night. ecspecially, at high speeds. Would like to do the "All Motor" &/or stock suspension classes, but I have enough NOS to nuke a small town for my 440 build & for future use (2) 106MM turbos for the alum HEMI build. Won't even need the 7.50 cert at first but at least it will be all done right.




A pair of 106mm turbos on a Hemi will put you well past 7.50et's unless you never use more than 5psi I agree with prochargedhemi, take the time to go for the 25.3 cert.




Once I finally do get to the turbo build. I will probably just run of the one 106's & use the other one as a spare or a parts turbo if ever needed. I think it is too aero disadvantaged to ever go 6's easily. The front end is just a big scoop. Leaving it all steel. No solid front one piece lift off front end for me.
