J/K.. I'm really glad yours went smooth for ya.. I hope mine goes together that good, even if it takes a few weeks longer...
Running TTY Bolts is a waste when you are building a motor. I know you think that the TTY will do the job, but in order to build your motor at a machine shop, you will need more than one set of each the heads and the mains. You will need a set for the mains for each time you put the caps on and off, which is about 2-3 times. Then you need about 1-2 sets for when you bore, then hone with TQ plate, ect. So when you are done, you have spent more than ARP stuff and are still not as strong. Hope this helps.

The GT67 will be done for on a 408, but I really want the torque. as the build is getting closer, I'll more than likely be going with a stock crank.
I doubt I'll need to much psi from the turbo, seams as I'll be so high on compression as it is..

Dusty,
I was thinking that I can save you some money on fuel to put toward that hotrod stroller!
We will be out there "Utard" at the end of this month, Brent and I can pick up your block for you if it's ready.

I don't think people have give the factory tty bolts a fair shot. Everytime some one cracks a piston and rebuilds they use studs.....
Seams how I don't plan on removing and reinstalling my heads I don't see any advantage to studs....

I have 850-900hp at the flywheel in my DD pick-up with stock GM bolts. I do not drive it with the high boost all the time, but it gets a fair amount of beating time and some trailer towing. After 60,000 miles we pulled the heads to try a different set. We did find some carbon tracking showing some head gasket leakage had happened, but I have rattled the engine a few times testing methanol kits which may have caused the leak. Overall the factory gasket/bolt combo has been very good at the lower power levels, like Hellbents10 I would say 900hp is a good limit for the fastener. The other consideration for guys pushing them hard and working on them alot is the threads as mentioned. I have damaged a few blocks on dyno mules just changing the heads to often, a stud would protect the block threads while typically having more engagement of the factory threads. One of the reasons we use 1/2 studs is to increase the thread contact on the higher torque fasteners.
