Wow tough day for the new guys.  Unfortunately I can't help you with this question.   Just off the top of my head I would say, look for obvious damage and/or repairs.  Check for soft spots in the floor and stringers (beams running front to back on either side of the centerline) assuming there is not a flat floor.
My best advice is to take it out to the lake and run it although I have not done that with either of mine.   Stupid of me but I have been lucky I guess.  Be sure to check the trailer equally well for serious rust damage/weakness and see that the boards are in good shape.   There is at least one guy here who live in Norco, maybe hook up with him.
Ray and Nordie must be working today cuz normally they have something to say about everything.   Welcome to the site mdrnrod, hope you stay awhile.

with the flat floor it might just be a 1/4 stringer boat...i always like to bounce on the floors to see if it is solid....it will tell you exactly what you will be getting into...9 times out of 2 there is foam underneath the floor and it gets water logged, and makes fowl smells, and adds a ton of weight! cracks in older boats is very very common especially in mounting places! firing right up is a plus...what kind of motor and jet pump some motors and pumps are more desireable then others...there's alot of things to take into consideration when purchasing a boat!

it has a ford 460 and a berkley jet

tahiti's were one of the mass production boats of the time, still many around. the only thing that would concern me is what the guys have already said.

on a side note, when it comes to resale value they dont seem to hold because of the mass production. jmo

the price seems rite, but without pics its hard to tell.
