LQ4 Cam options
#23
#24
I will just throw my name into the hat with our Saturday Night Special Stage 2 TorqueMAX cam. It is 227/235 .614"/.621" 110+3 and has been a real hit lately with anyone that buys one and used one.

Did some research and I found out my converter is a D5 converter, which has a stall of about 2200-2400rpm behind a turbo v6. (not sure what it would stall @ on my lq4 ?) I would like to use this convertor if possible to save money. Sorry for changing my mind so much.
- what cam(s) would be good with this converter?
- again its for a street beater that may see a few track passes eventually

IMO, with your 2200-2400 stall I'd go small, like a Comp Cams #54-455-11(215/223 112lsa+5).

I would take a guess that if it stalls 2200-2400 behind a buick V6 with less torque that it should stall to at least 3000rpm behind a LQ4. That is just an educated guess though.

No, not yet but I am looking in to it some more.

If I were you I would like to see where the old stall flashes with the new larger motor. The new motor will be making more torque down low than your Buick was I would think, which will loosen it up.
That said a 3600 stall is the normal choice for most street/strip cars and with that stall, I really like our LS2 Stage 2 TorqueMAX cam. It is 231/235 .617"/.621" 111+2 and would work great with that size stall.
If you kept the stall you have now, I wouldn't go any bigger than our LS1 Stage 2 TorqueMAX cam which is 227/235 .614"/.621" 110+3.

I would worry about hurting the stall long term and in turn hurting the tranny. Used to be popular for the b-body guys to use S-10 converters to get a cheap 2200stall and given time and use stockish LT1s would lay over the fins.
I understand the converter was a turbo V6 unit and will likely be more durable than the S-10 one but your engine will be making a good bit of power too.

96caprice is most likely going to be correct in his assumption. You may actually end up damaging the converter.
I'd call PTC or FTI for a nice 3600 stall and pair that stall with my LS2 Stage 2 TorqueMAX cam. 231/235 .617"/.621" 111+2. It would be a perfect match for the stall and engine size. It will also drive very nicely with a stalled auto, 364 cubes and that camshaft.
I have a customer making a little over 400rwhp with that camshaft in a LS1/4L60E "cam-only".

Just a recap
-Lq4 .020 overbore
-ARP studs and bolts
-243 heads (stock head gasket)
-LS2 timing chain damper
-Tick LS2 Stage 2 TorqueMAX cam
-BTR SLR lifters
-BTR .660 Lift platinum springs
-long tube headers
-3600 stall
-200-4r trans
Any guesses on power?

The original plan was to run it as is, but when I opened it up it was disgustingy dirty and carboned up. I wanted peace of mind so I took the block to the machine shop and had them check it over. It had .005 wear so they reccomended the .020 bore. The crank was in good eough shape to be polished.

It does have lockup. I have already ordered the upper engine gasket set (inc. stock head gaskets). I figured I would get the heads milled if ptv clearances were large enough, would 040 gaskets be the smarter choice than milled heads?

A thin gasket improves quench and detonation resistance, plus a .010 thinner full bore thinner adds more compression than milling the chamber .010 because the chamber is not the full size of the bore.
