I'd say 850whp+ for sure with a 2.95" blower pulley. different setup and was a 427 with MAST heads and slightly bigger cam but I just made ~850whp with a smaller D1SC blower with 3.55" blower pulley and I think I was having belt slip and some fuel issues.
if you're working with Arun that guys knows his ish but one thing i'd say is just be careful with the 243 heads, I had those on my last stroked ls2 setup and while the tune was a horrific mess done by someone with no business tuning, it was lifting the heads and i've read the 243 have at somewhat thin deck so easy to lift the heads. sounds like your motor is already together maybe so if so i wouldn't sweat it but if not and you can swing it maybe go with some aftermarket casting heads, even texas speed I think have the thicker deck and they are good price
I'd say driveline should be fine for street beatings, but if it were me i'd just replace the rubber couplers while its apart depending on the mileage they may have on them. They take a beating on these >600whp cars and can get little tears in them. It's cheap and easy to replace while the car is apart but if you have to do it later the whole drivetrain has to come out of course.

dont go under 10:1 unless you plan on running big boost. you just rob yourself of extra hp and low down torque. 2.95 cog at 9.2 and decent heads u may only see 15 or so # of boost, speak to a few shops about comp ratios and ur setup and goals

well that's the thing. I will be running big boost next year once we switch to the 2.75 pulley. unfortunately up here in Newfoundland Canada we can only get 91 octane fuel so we are keeping the compression a little lower and running 100% meth to help out.

a 2.75 isnt big boost. that will fetch u under 20lbs on your combo. im talking 25 plus. im running a 2.95 and only drawing 14lbs. e85 available?? fuel availabilty is an issue on builds like this

I think he would make more than 20. My 402 has bigger headers and better flowing heads, and I make 19.5 lbs with a 3.0 pulley.
Every setup is a little different so its tough to know exactly.
Sounds like a fun build.........

I know fuel availability is an issue that's why we are keeping a lower compression.... and as canuk said every build is different. hopefully in the next week or so everything will be buttoned up and we will see what this old girl will put down.

another update......
well guys we are slowly making a little headway. unfortunately there is more delays. the stroker kit still hasn't arrived in Vancouver yet which is baffling as this was ordered months ago. for future reference ill just order my own parts... anyways the motor is out of the car and dismantled. he is also installing and running the gauge pod and gauges and also installing the meth pump. that's all we can do at the minute until the rotating assembly shows up
so I got to thinking about running the car in the 1/4 mile next year and came up with a list of parts that im going to start ordering. im also going to pulley down next year with the 2.75 and aim for 1000 rwhp or so. so here's the list of parts and you guys can tell me what you would add to it or subtract.
DSS left and right hardened half shafts
DSS carbon fiber drive shaft
DSS level 5 axle and hub package
ECS trans and rear brace
ECS torque tamer
Brembo 6 piston front breaks 14"
Brembo 4 piston rear breaks 13.6"
LG motorsports GT2 coilover kit with upgraded sway bars
RPM level V six speed trans
Hoosier 275-40-17's DOT slicks on 17 inch repro zo6 wheels
so what do you guys think???

What happened to being in a budget?! Hahah....im the same way...we should all move to collecting diamonds and drugs so we can have cheaper addictions...lol.
I was not thrilled with the Hoosier and thing there are better options out now. They were sticky when brand new but did not age well. I'm going with m&h race masters as replacement.
That's all top shelf stuff though. Not sure if you're still on a t56 but if upgrading drive train do the tr6060 for sure or don't do the upgrade imo
