Matt those are trw forged pistons. They are are good piston just a little heavy, but generally work great. Will give about 10.6 comp. With cc heads.

Matt the pistons will go to 7000 grand all day long it's the rest of engine you have to worry about. Do a search on here about the oiling mods and you will need the right cam and valvetrain. You will find however you can make alot of power below 7000 so get some help with the right cam. There is a bundle of knowledge on this site.

I spin my pistons L2379 flat top TRW's to 7500 rpm with the occasional 7800 rpm. They have been in there since the early 90's. Brian

ive been a member for a while just have not had internet to keep in contact. i agree, im gonna have to do some searches again-which i did for the TRW's. I would like to get 600hp+ n/a out of my 357c. i know its not easy but i know its not impossiable. ive got a few solid roller cams in mind that i think will do it. still just wondering if i should go with the new Trick Flow 225cc heads or CHI or AFD to do it. Any thoughts or recomandations? Thanks again, oh by the way, mains already have oil restrictors and oil returns ports have been chanfered on block.

Matt Its a tough call on heads because the stock heads can support 600 hp.If you look at the following thread Paul has listed his 2v iron headed combo and if you crunch the no.s he's right around 600hp.Thats impressive to say the least.I had a set of 4v closed chamber heads flowed that I ported myself and they flowed 325 cfm.That is good for 600hp with the right combo.I would say if you have a good set of heads I would put the money in them and go.If I would have found this site before I bought my CHI heads I would've stuck with them.However CHI has good product,also Scott Cook has a new head that seems to look good so far.

I have no idea on HP and torque. I can tell you my 65 Comet two weeks ago ran an 11.54 at 116 mph. It has the old Crane F260, Strip Dominator and the heads are 4V quench chambers. It is a 4 speed with a 5:14 gear and MT 28x9x15 tires. I am afraid to do a leak down test as I am not quite ready for a 393 yet. Brian
