What If the announcement for a Tenure-Track position in a research-intensive university does not request a research statement?

If a TT position is announced in a medical-related field in a research-intensive university, and they request to apply using 1) a letter of interest and 2) a CV (No research statement is required). They say the candidate's time would be divided between research 60%, teaching 20%, and service 20%. Would you still submit a research statement or would you just include in the letter of interest more details about your current and future research (this might require making the letter little longer ~3 pages)?
