Kicking around ideas for Spring setup

[BR3W CITY]

So I've been running my lq4 with the Tsunami for a while, and its a good bit of fun, but I've been ready for more for a bit. Last year we put off more performance to clean up the body/bed/interior...but its not fast enuff

Our long term plan is still to go FI, but we have at least 3 other builds that we are inolved in this spring so its unlikely that I'd have time or money to do it this year....but we still want to have some fun on the truck.

A friend who owes me some favors has got a stack of parts we may throw on the truck, in one combo or another. Here's what we've got, so tell me what you think.

We've got a set of VERY nice ported and milled 317's, done by a very reputable guy at SAM. They are down to a 69cc chamber, and have been flowed, having #'s as good or better than the TSP cnc ported 317's through about 90+% of lift.
They are fitted with Manley proper length pushrods and all Manley Titanium valve retainers/locks etc. New gm valves. Either my PRC or another set we have of Dual springs.

We have my TSP Tsunami to re use, or there is also a very nice Tick Blower Cam. I know we may be down a few #'s on the blower cam without the blower, but its a surprisingly good cam without the blower (I'll post the specs).

He's got an LS2 manifold laying around as well, along with the rest of the intake path.
- this brings up some seperate issues.
I need/want to keep my lq4 dbw pedal/tac because of how it had to be made to fit, I'd rather not redo that. We need to figure a way to
A) make an offset spacer to tilt/angle the TB on the manifold so it will clear the truck water pump outlet (not changing my accessories).
B)run the ls2 90mm TB using my existing dbw control (tuning is not an issue, we just don't know if this can be done without an xdrive)
C)make that offset spacer for the tb also convert down to the 3 bolt 80mm truck TB so I can use it on the ls2 manifold.

I would likely pickup an aftermarket rail so I can run the ls2 intake, but keep my return style fuel system which I prefer for a few reasons. I may/may not step up to 60# injectors from the 39-42's that I have now.

Lastly, we need to upgrade from the TBSS manifolds to a real header, as I'm leaving too much power out. DT's are a popular option, but we have access to a machinist/fabricator who can make us custom headers for the material cost. Either way, we'd be looking at something similar to the Doug Thorley big tubes (whether or not its actually DT brand).



Thoughts? This is driven by the words FREE/CHEAP/FAVOR, so its unlikely I will stray too far from some of what is listed. We just aren't sure which way we want to put it together lol.
