Why LS swaps made everything better

[motorheadmike]

I don't see an issue reusing the bolts if they're not failed or fugged up. That's why I think it was a money grab by bolt manufacturers. Believe me, GM recommends buying NEW bolts every time.

For those wondering about whether to reuse TTY bolts, there was some pretty decent and comprehensive testing done on GM TTY bolts compared to new bolts and other brands and it was suggested to reuse TTY OEM bolts 3-5 times. Believe it or don't. But if you have doubts, replace the bolts. It's your money and peace of mind.

For Powerpoint and Excel files, here's the link.

For those who don't want to rifle through all that, here's the summary page below. Basically, he suggests ARP bolts are high quality, but not worth the ROI on a stock rebuild, but good for high HP applications. Chinesium...fuggedaboutit.

You beat me to it! I just spent 20 minutes trying to find that. LOL.

I spent a bunch of time cleaning the used bolts up, lubing the threads and underhead/shoulder before running them in. Seems to have worked out okay so far.

I have a set of ARP studs for the 4.8L... they cost more than the whole engine.

Seems a bit too easy:

And if money was no object:

I re-used the 4.8 TTY head bolts and put down 23 psi by mistake on the 2nd hit.

The right way, the wrong way............ the LS way

BTW 23 psi on the 4.8 made 675 whp with the ultra conservative tune 1st time in the dyno

You do know that I have reused TTY head bolts in my boosted 5.3, right?

And he puts it together with an impact gun.

I can't count the number of times I've reused TTY bolts, even on boosted stuff. Never had an issue.

Currently researching Rommel for school... I am dying here because this hits me on so many levels.

My sides hurt the first time I saw that.
