Olds 455 or pontiac 400

Hey guys, you might have seen me in here before going on about a olds 403 but today I have a new question. I have a '81 trans am with a TH350 and a 3.73 posi. It is my first project/ car. This is going to be strictly a summer car since we have salty winters here in Canada. I am looking for a street and strip build. I plan on being at the track as often as I can. But I also need to get around town and very rarely on the highway. I have already picked up a olds 403 with the TH350 for pretty cheap ($150). Anyways I was chasing 450hp with the 403 and eveyone said to scrap it and go with the 455. As much as I protested I did go look at them. I came up with a Olds 455 from a 1970 olds toronado GT. That means it already puts me up there at 400hp and 500 ft lbs. So with some headers and mabey a intake and new cam I can get neer 500ish. The good part is it will only run me $500 bucks and after I sell the trans axle and all that comes with the from frame Mabye around $250. The bad part is that it got a little water down in one of the cylinders and now wont turn over. Another good thing is that the guy who owns it now put some diesel down the spark plug holes to mabye break it loose. It has been a while since he tried to turn it over again so who knows? Anyways what do you guys think? I have also seen mid 70's and very early 80's pontiac 400's. I am just wondering if I should risk the olds 455 (I think so) or just go with a pontiac 400? I am looking for the cheapest route to go so what do you guys say?
