Well we need a little more info then that. There's a lot of variables that come into play....tune and boost being the biggest one. May I suggest proof reading your title and post first next time? haha. 317's don't have the thickest deck but you can still lean on them pretty well. I assume you have ARP head studs? 7 Layer MLS or the LS9 gaskets? As long as you don't get to greedy with timing/ tune you shouldn't have a problem running into the high teens or low 20's on boost. I'm sure many others will agree that the tune is the make it or break it factor for the most part.

Can't edit it already tried. Ls-9 gaskets and head studs. The heads flow 317-318. Also meth for now. I do not think the f-1 will make that kind of boost

He wont see that kinda power with that setup. But OP Im probably pushing my setup as hard as anyone here but I do have a little thicker head than you and the same gaskets but my compression is at 10.7 to 1 and Ive had no issues at my power level. jeff

I don't think 900+ will be a problem. For reference/comparison sake, I put down 830rwhp on a dyno dynamics with my 370/ Old F1 combo on 18psi. Since its the older version, the step up ratio and the rated flow are a little worse then the F1A. Like I said from the begining as did a couple of the other guys who know their ****, the tune will be the make it or break it point. You have a good tune, you can get away with a bit more lol I think you should be able to surpass your goals and be pretty safe. Just follow the advice posted and you should be well on your way!

With 317 head casting on my 370 with ARP studs and MLS gaskets i wouldnt push water on the dyno till about 23psi and that was 1100+rwhp. That was thru a S88 turbo and a Powerglide and S60 rearend. At the track i would start to push water and pressurize the coolant system right about 20-21psi. As you can see the dyno wouldnt load the car as hard as the street/track.

From what I have seen, you'll push water sooner with a blower than you will with a turbo. As a general rule of thumb, I don't recommend going past 16 psi with a blower on stock thickness head decks. This is with using MLS head gaskets and head studs. Bob

I had an iron 346 with 706 heads on it, cometic gaskets, and ARP bolts (not studs). With a D1sc pullied to 106% it recommended max. It made 23 psi boost according to the map sensor and never pushed a drop.
Then again, I got it to push water one time on 14 psi. If I recall, when it pushed it had 24* of timing in it with pump/race fuel mix. Tune up has a lot to do with it. As I said, it didn't push a drop at 23 psi, this was at 20* timing and C16 fuel.
