I need some input, I'm looking to do a 393w, but the pistons im looking at (probe 15cc dished pistons) with my FAC190 with 64cc would give me a compression ratio of 10:1. What are your thoughts of 10:1 compression with a turbo, say 15psi?
P.S, pistons and rods will be forged.

You should be fine, I am doing a 347 with 10:1 compression and 6lbs of boost with pump gas.

I'd definitely go with a custom cam, for fuel if you can get ahold of E-85 I'd use that.

C16 is pretty expensive, it'd almost be worth driving the 90 miles and filling up a 55 gallon drum to keep in the garage.

I like C16 but the price is crazy, I would run E85 if I didn't have to sell my 83lbs injectors and my classic F.A.S.T. to run it, to get to my power level. F303 cam works good with a turbo and one guy on theturboforums.com made a 1000hp with a F303 but a custom cam would be better.

Looks like the guy sold the kit i was interested in, oh well i'll just save up for a 408 down the road. I guess i'm going to run what i have. What do you guys think of a rebuilt stock F4TE shortblock with FAC 190, fcam, gt40 lower/Cartech upper with a t76 15psi, with meth?

I think that is a great combo but run about .035 first and second ring gap and remember the F4T 351 rollers use a different ring pack.

I pieced my 393w kit together having summit price match parts. I got the dished probe pistons and thicker cometic head gaskets to lower the compression. Im just under 10:1 with 61cc heads and 7lbs boost. You could also open up the combustion chamber on the head. Every little bit counts. Coast has some decent prices on their kits too if you dont want to pick your own parts out. Kind of takes the fun out of it with just buying a kit in my opinion though.

I think im going to run it stock shortblock for now, and lil by lil piece a 393 or 408 down the road.
Im curious to know what you put down with the 393w @ 7 psi. You can PM if you'd like.

Depends on hp goal but I'd run twin 255s and 83s with a stock block 351 should do the trick.

Hoping for low/mid 600s with a c4. How about lines/rails?
Would 80lb injectors work fine with stock ecu/sct chip?
