AFM/DOD delete on big horsepower
hello all. Trying to decide if I should go ahead and delete the afm/dod onmy base model . Current setup is sort of a “max effort” stock Long block car. Ysi with port injection and a 2.75 pulley it will only make around 17 psi ,I believe either due to valve float or stock Cam . I’m already pushing the limits of the stock lt1 at around 850 whp. But the power curve starts to fall off around 5800 rpm due to the issues above. Would it be worth it to just delete the dod and a heavier spring without doing a camshaft ? I hate the thoughts of doing Cam and dod delete without freshening the motor while I’m “that far in” especially since if I do a Cam swap and left the 2.75 it would probably not make it through the tuning process .

Ditch the DOD for sure. I wouldn't trust those DOD lifters at those power levels. We have some solid deals on DOD deletes and cam packages if you just want to dive into that for now and run stock short block.

I cant believe that stock set up is holding up to that power lever & boost on those pistons.

With that much boost, his timing is in the toilet, that’s why it’s still alive. Forge it and put some timing in it...and hang on
