Hi,

Did a search, couldn't find apples to apples info.

I am going to take my block down to the machine shop to get cleaned and bored. I wanted to know if there is anything substantially different about a turbo'd build that would pertain to the machine work, like looser clearances, etc.

It's a std bore '72 350, getting punched out 040, with stock N crank.

I have Probe SRS forged pistons, and 4130 Tomahawk rods. I think these will be fine for the job based on my hp goals.

My goal is for around 500 hp max on mild boost (maybe 10-12psi) from a single turbo. Nothin' crazy. I plan on building a stout 300-350hp NA engine first, and then toss on the hairdryer. I've only ever played in the world of mild street motors.

Anything weird I need to worry about, like extra cylinder wall clearances beyond what the piston manufaturer recommends?
What about ring gaps compared to normal?
Would hard-block filler be necessary?
Any special fasteners?
Additional input welcome.

I don't plan on spinning the motor over 5500. I am hoping I don't have to get too weird beyond standard performance engine building practices.

Thanks!
