a blown tranny?

With the proper springs and ****Z.

**Schwuppes** · 01-25-2014

valve train shouldnt be a problem... 130lbs springs, modded retainers and valve stem seals, double row timing chain. And my transmission is fully built... has been putting up with over 400 ft/lbs at 2800 rpm since i got the a2a cooler last year

who gives a **** lol... these motors have been around for 50 years in their basic design... and they're pretty much bullet proof.
Just not balanced very well from factory i hear

the balance issue is a mater of 3rd and 4th order harmonics from the close coupled rocking inherent in a 90* bank angle v6 (the sbc v6 also suffered from this)
....this extra NVH is removed by a more inherently stable 60* bank angle v6 as are ALL of gm's current v6 offerings

Never said you could swap parts from a chevy to a 3.8. They have the 90° v6 design exactly like the chevy. Not like buick They had a wide designed intake.
The wide intake was actually a pontiac design.

And trolling I am not. I didn't say the diesel was designed by izuzu. Try reading for a change. The duramax diesel was designed by izuzu. Troll on.
His name was Rudolf diesel by the way.

Ok then ANY chevy design is actually a caddy/olds design as they camw out in 1949 and the 265 chevy was based off them, same engineer in fact. And i never claimed the duramax was designed by chevy, so mebbe YOU should try reading for a change

Thanks ice. Hmm Learned something new.
GM has owned it since 1962 and sold it to kaizer/jeep in 1967.

Ok you got me on the diesel comment, I misread your comment.
But, in 1908 david buick changed the name of his company to general motors and it has been since. So EVERY motor that has been in a buick since that time has been a GM engine. As with GMC, chevy, and all of its subsidiaries. They are all GM.
Sorry for the threadjack.

I've got mine setup to shift at 6250, actually shifts closer to 6500.

Stock bottom end I wouldn't run much more than that on a daily basis.

All else fails, get another motor and balance the entire rotating assembly and rev the **** out of it.

**Schwuppes** · 01-26-2014

i think I'll just tell him to shift at 6200rpm... limit at 6500. That sounds like a good compromise.... mine currently makes it peak power at 5200 rpm... so an extra 1000+ revs or so will do me nicely

**pontiac4lifesc** · 01-26-2014

they usually rev a little higher than the set point. i have mine set at 6200 and revs just a tad higher and other guys have said they have seen 100 to 150rmps more than the set point.
