Hope you love the new torque its a game changer. You must have stupid money , someday I will again but kids college ate it for now.

Realistically with a stingy dyno I would expect low 500s from the heads and such and more mild compression for pump gas like mine on 11:1 ;but you can with maybe some timing pulled do up to 12.5 on premium though around here theres non ethanol but corn...you have to go out of the way for that more than just race gas...LOL SO you get a stroking and it is going to show but change in cam? I picked one with wider LSA and more torque friendly just to take it easy until I could afford some day another round of build with more a max effort stroker cam in mind someday with ls7 small bore heads.

That's from knowing so much...like cost $$$$$ of a ls7 and its lack of material to hone making it a one time shot for the block at .005 make LSX blocks more inline with aftermarket Darton etc.... so much more attractive for a future build when the most cost effective being simple stroking and clearancing of a ls3 block with the right parts done right pistons made for it. Ahhhh dreams of more power to get to work.....LOL

Anyway years to go until I can afford more and Hope you get a good pass on the track someday, I know I love my Monster clutch its like stock and my stock one took just being cammed fine and both feel the same. Have heard though people with lots of clutch chatter off some supposed great spendy clutches that just well.....I would not tolerate..LOL Launch those groceries around the trunk, annoy the neighbors.....

No stupid money here, my wife and I have worked long and hard for everything we have. I'm even working 2 jobs again, to get what I want. And, speaking of college, I just watch my daughter cross that stage today and your right it's not cheap, but if it's important enough you will do what it takes to get it done.

Now to the car, we did talk about changing to a big stroker cam but I decided if we change the cam again I would go with a LLSR from Kip @ Cam Motion and make this into a drag car. Right now it's still a great street car, that can be used for AutoX, and I could throw a 100-150 shot on it and still have fun at the track also.

Here are the results from GPI for the 416 Max Package Build. We are still going to add 3" exhaust with x-pipe and Carven 3" R series mufflers next week.

Gained about 30 more RWHP and 45 ft/lbs of Torque. I am thinking i may gain another 5-10 hp with the exhaust, but who knows. Either way pretty impressed with GPI once again, and can't wait to get her picked up.

I hear ya brother. Maybe next time we will go LLSR or may through a little nitrous to it, that way I can still autocross the car and drag it on occasion. I have got to get axles and a drive shaft next, before I star breaking xxxx.

Thanks Ryan, car is going to be a blast.

Thank u Doug!

What a fun motor this is going to be. Should be in the 10s pretty slick with some high 120 traps and could spray into the 9s. When that centerforce gives up RPS twin carbon with aluminum flywheel would feel like you freed up another 40 foot pounds of torque on throttle response. Lighter clutches do wonders in these things. Great build! Glad to see some not so average stuff starting to shine through.
