Chances of killing my carbed 5.3 with twin 70s on 6psi.and would that get me 450rwhp thru a th350

Why twin 70's for only 6lbs? You can probably get away with a single 70 and run 6lbs more efficiently.

What is done to your 5.3? More information and more detail will probably get you more accurate answers.

What he said. Why run 1000+ HP worth of turbos to make less than half of that?
This is usually how it starts before people start complaining about poor efficiency and turbo lag.

A single 70 should be good for more than 450whp through a TH350.

Yes, your 5.3 will handle it.

Well motors stock now just wanting to get good street able HP and still b reliable.not looking for a drag car.just sumthing to punish sum cars.its n a 89 s10 that I'm wanting to keep sleeper. I think 450 would b very stout with it being semi light.and wat gear would y'all recommend. I have 410 now but was thinking of going to like a 327 for highway if I go turbo

JoeNova

Depends on what size rear tire.

usmc53

27" tire

JoeNova

3.27 is a decent gear then but I would try for a 28" tire. You can always change tire size down the road as long as your gear ratio is ballpark.
