Best choice for engine project?
#3 definitely clears out a lot of garage shelf space! Could probably spruce the appearance up a bit with a set of red Holley tall valve covers, red WARR 102 TB, and a few other tweaks.
#3 is unique a collection of spare parts. Would look pretty ordinary but each part has a backstory. Used Nascar racing spec LS2 block from truck series, my old cam from another project, used & reworked by Bret of Land Speed Cylinder Heads (formerly of Katech) GMPP/LPE LS6 heads w/new mid lift VJ optimized for 4 inch + bore, Black Friday special deal on Summit crank...etc

For option #3, personally I’d go a little smaller on the camshaft or have 4.10s with quality 3200-3600 stall converter. This cam would like high rpm shift points that 4L60-E may not agree with.
If you go with option #3, I might be interested in LPE LS6 intake.

Blackgloves, definitely do a build thread! It's always cool so to see what folks do and watch the progress.
I want to refresh or replace the 4L60E before doing anything motor wise. Going LS2 Stroker will push me towards a RPM Transmission Level 5 4L60E. It would take anything my NA LS2 Stroker could dish out. Getting the RPM Level V done would take most of 2023.
I'm pretty slow 🐌 with builds please see 1 in 1000 high mile 02-z28's new lease on life. Has taken 4 years to get the 02 Z28 to this point. Here's my 99 T/A build from 2017 that went a bit faster.
Cino, that's a fair point about the 239/244 cam, could be bit big and high on the rpm. Would have discuss with RPM Transmission and see they felt the Level 5 4L60E would be suitable. Agree, may have to consider a smaller cam when talking to engine builder etc.
Will definitely keep you in mind and in loop if the 90mm LS6 intake comes off car.
Can feel the project creeping 😭 ....wink

I find it hard to believe the Hot cammed LS3 is leading the poll, SERIOUSLY!! I'd get the std 430hp LS3, yank the OEM cam, call Futral or Cam Motion, and POOOF-Instant circles will be running around that Hot cammed LS3, plus it'll have better throttle response, more horsepower, more torque, and equal/better gas mileage. IDK.....To me, it's a no brainer. The LS3 is a 21st century engine, with last century designed camshaft. A LOT of power being left on the table by going with that "Hot" cam, and driveability with a better cam will be just as good. .525" lift??? C'mon, man.....

Excellent points by all about ye old not so hot, hot cam. Agreed, the old GM Hot Cam is suboptimal in anything. Hate idea of buying a new GM crate and saying screw the warranty though.
A) The EPS 226/230 113+3 cam in the GMPP Crate 430hp LS3 would would be better hp wise than a Hot Cam. I think the valve events would work OK in an LS3, some one please feel free to explain if I'm wrong about that. Doesn't have the massive split etc that's so popular etc.
B) Likewise an LS3/L99 short block, use GMPP LS6 heads, Mamo 102 intake & EPS 226/230 113 cam plus LPE box could also work. Probably be down 40 to 45 wtq from the LS2 404 but make similar peak hp.

With big cc GMPP LS6 cathedral heads, instead of buying rather expensive LS3 short block, you are better off with LS2 based 404. Big cc GMPP LS6 and smallish EPS camshaft may not be the optimal combo, but by all means NOT a mismatch of parts involved and still fun, potent engine considering using your existing components.
404 LS2 Stroker, GMPP LS6 heads (~245cc intake ports), EPS 226/230 113 cam, Mamo'd Fast 102
Have cam degreed to get ~47 on IVC even if that ends up being at -3 etc?

Use the ls2 block for the 402 and do yourself a huge favor and hit the Tony Mamo easy button. Let him tell you which of his heads to use and let him port a Fast 102 and also spec the cam. You'll have some money in it but it'll hit harder than that ls3 crate engine ever thought about. With a baby cam to boot.
