What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Dantheman1540]

yup thats the area i was referring to. very odd cylinder wear still. and at 25,000 miles too. id pass on that as a go fast short block.

I don't know that exact part numbers on what pistons but its a full **** rotating assembly and I believe one of their more budget friendly options. likely not as much R&D into preventing such wear. This is one of the reasons I haven't built a stroker yet. I'm really curious to know what the culprit is determined to be.

No its pretty old I'd say 4 or 5 years since the previous owner built the motor and I think he did it himself. Just glad my buddy caught the low oil pressure before it became no oil pressure and a windowed block or tore up the precious heads. Those PRC 247cc heads are not cheap!

Same exact specs. I didn't want to go for a retune. Plus the tech guy told me the stage 4 is maybe another 10 horses--forgot the tq tho. I'm good with this one--for now

...But we found its actually a
Towmax Stage 1 208/216 | .561"/.561" | LSA113+4.

So no point in putting it in my tahoe. However it would be a great cam for a 4.8 or 5.3 that wants towing torque if anyone is interested I'll probably post it up for sale.

Either mine is much bigger than I thought or that one is tiny for a 408! Mine is 212/218 | .550"/.550 | LSA114

Its an itsy bitsy cam and pretty much a waste of good cubic inches and badass heads. The next cam will likely be in the range of 23x/23x .630/.630 on a tighter LSA like a 111-112. Unless he disregards all my suggestions goes big dick swinging and gets something that he wont be able to tow with. I hope not because I always end up towing his crap around
