Glad to see the speed density boogie man is still running around in full force.

Speed density tables are significantly more adaptable than MAF tables will ever be because they can't read the amount of incoming air. Depending on modifications, a speed density system may not be able to compensate, but there are members of this site who have successfully used the E303 on SD EECs (88workcar to name one). One of my old friends had 24lb/hr injectors in his 87 GT for a good 2 years even without an AFPR without signficant problems (he did have some idle surge issues from time to time that he needed to tune up).

24lb/hr injectors are unnecessary for virtually any NA EFI E303 cammed 5.0.
