Looking for some advise on my turbo selection. My setup is a stock 292/th350. I have a clifford intake with a tbi efi kit for it already (not running yet.) This will be on a little cruiser '65 c10. So, not looking for a strip monster or crazy hp numbers. Just a little more pep with good street manners. Is 300-350 whp feasible?

What are your thoughts on these two units?

At first I was thinking about the 70mm turbo but now I feel it might be too big. The 61mm is a t3 frame. Would it be too small even if I went with the larger turbine? I'm hoping to hear your opinions and thoughts.
