Default Expected 383 Stroker Dyno Numbers?

Hey Guys,

Getting a little ahead of myself, I would like to ask you guys if you can ballpark what you think the dyno should say at the rear wheels. It will be all together next month, and hopefully a TON of FUN!

I have an LS1 with an Eagle stroker crank, Eagle featherlight rods, and Mahle pistons. It has Brian Tooley Patriot springs with titanium retainers, Manley pushrods, and a 3726R/3729R HR111 232d/238d .595"/.605" 111LSA Comp Cam, stock rockers with upgraded Trunnions, LS6 intake, 1 3/4 OD ceramic long tube headers, however it has STOCK LS1 heads that have been port matched. Stock throttle body. 4.08 final drive. Aluminum driveshaft. Light flywheel, cant remember what the weight was. The PCM will be tuned for the upgrades.

Thank you in advance for anyone with some insight!!!

With the stock heads it will be torquey but not crazy on the top end. Pretty much a guess I'm thinking 410hp/450tq. Get some heads on it.

Not a chance itll hit 450rwtq with stock heads...410rwhp is a good guess though.
I'll say 412rwhp/388 rwtq. The stock heads are gonna hold you back!

My guess-o-meter can be off sometimes. On second thought moe is closer. Either way broad flat torque falling off early.

Thanks for the input guys!

I will post dyno results as soon as I can get them!

How about with a set of Trick Flow 255s? What do you guys think the numbers might be with a set of those on there?

If your talking about TF's new LS3/L92 heads, you would need a 4" bore at minimum to run those heads...

MoeZ28, these are what the guy at Trick Flow recommended to me with the setup I have.

Do you see a discrepancy with my setup and these heads?

Thanks again for the input man, i really appreciate the help.
