Ahh okay, and I have a posi rear end so I’m probably safe there and my tranny was rebuild and has heavier duty springs, abt 1000 miles ago

 

Unlikely either will hold.

They don’t with NA cam/headers.

Then there is the driveshaft issue.....

 

It’s not going to be cheap, I got about 10,000 into my truck and that still don’t include the turbo kit.

 

With that turbo it may loose power.

 

Lol. Just from a flow perspective.

 

50mm’s are usually good for the 300-350whp range but on mid teen boost levels. You would definitely need two of them for it to work right on a small block. I ran a single hx35 holset on a 5.0 ford motor and it would peak torque at like 42-4400 rpm because the hot side wasn’t big enough for the engine. Fine for the truck it was in but made 236/339 to the tires on 7lbs.
