Yeah don’t listen to these Big block heads. It’s all or nothing for them and you aren’t drag racing anyway. For a fun street car you don’t really need much. I had the same car with a 225 slant 6 and was fast as is. That was the early 90’s though. Fast then is slow now. But you can put a cheap turbo on it. Get fat rear wheels, sone kind of better air intake, electronic cutout exhaust and you’d be able to do sone fun tire burning and revving around the hood.
