What engine for racing to put in my Duster

Just want some ideas and opinions. I want to get back to racing,kinda street strip, and I have 3 engines to chose from. One is my 383 from the early 80s,no heads for now, but ran 11.60s at that time in a Duster, next is a 360-380 built by me ready to go,but these heads have cracking issues I now know, next is a 5.7 stock engine. The 383 and 5.7 would need money for parts but the 360 is ready to run with the good roller rocker kit and cam. Where would the money and potential be best spent? Remember I want a street strip car but no dog. Thanks.

Throw the LA in it and have fun.

The 5.7 would be my preferred choice but it's an expensive proposition to get one to fit in an A body.

I would put the 360/380 in and go also. If it has Magnum heads, they do tend to crack but most of the time no leaks or operational problems that take the engine down so maybe no biggie.

360

Thanks for suggestions so far. Might add, on the 360, I have the RT cam in now but I do have the 501 cam. Which one to use(1.7 mp rockers)? Never ran a small block, what size headers?
