I recently replaced the engine with a used '97 L31 roller cam engine and L98 heads from a third gen camaro (one of my stock swirl port heads was cracked). I have replaced the fuel pump and increase fuel pressure to 15 psi as recommended by EagleMark. The truck runs fairly well with the new tune once it is warmed up. When I first start it the engine rpms surge between 500 to 1200 rpm and sometimes stalls. When I put it into drive it settles down some, but it is still there. A few times it has tried to stall on me pulling off from a stoplight. Once it warms up it idles steady at about 500 rpm. I have only communicated with Mark thru his personal email and phone and I don't want to bother him right now. I hope he is doing ok and has a complete recovery.
Thank you in advance.
