I have 10 k miles 600whp low boost on my build motor built by a local machinist that I trust.

Soon to be 700whp high boost .

I am not saying 9/10 die, I am just saying he wants reliability and a built motor does not always equal reliability when it comes to cars. Especially if all he wants is ~500whp for daily driving it seems like a waste and could cause more headaches. A good tune, install and boost controller would be an overall better investment where he can drive daily on a lower boost setting and then turn it up for fun runs. Plus in 5 years time he might be onto a new car, different path with the Z, or something else and the built motor was a waste.

I am always willing to accept constructive criticism and appreciate all that put forth info into this thread.

I was primarily looking for feedback on build components itself, however much of the feedback here is geared towards scrapping the idea of built short block and keeping the oem block.

It is always a risk tearing the motor down and rebuilding. As stated just because your putting forged components in, if install or tolerances are not on spec, disaster will come shortly later. Many are running more then my goal on oem internals; maybe I should just set aside funds for the block if it is needed down the road. Yes, it may or may not be needed, I may end up spending more money down the road on labor...decisions decisions...

Setting money aside just is case is a wise choice keep your eye out for a spare block. I got lucky and found a spare long block for really cheap right here on the forum, I grabbed it even though my stock one is built already.

i have a question. first off this thread has had lots of good questions and info so far so

my question is with a stage 2 kit and a stock block you guys are saying 550WHP is about the max "safe" power? i keep going back and forth on if i'm going FI or not based on my upgraded transmission price woes. my real goal is to get a stage 2 TT kit and run 10-12PSI hopefully hitting 500WHP minimum. i do DD my car in the warm months. right now it's put away for winter. i drive pretty normal to and from work but i do take it to the 1/4 mile strips once or twice a month for a couple runs. i wonder ifi can get away with that and keeping a stock block?

From various dyno graphs posted, the stage 2 pushing 10 psi + on stock compression exeeds 500whp easily.

i'm just hoping if i go that route with TT i want 500WHP atleast but not trying to dump 3k more into the block when i'll be dropping 6k on the GTM upgraded transmission since i have a 7AT

I'm stage 2 but I'm 6mt. 500whp will not be a problem. Read my earlier post about driving habits and u could use that as a guideline somewhat. These motors r pretty strong already. I take good care of my car, that being said I use the stage 2 the way it was meant to be used! I have 1 map only and it's set at 12lbs. Well I got 2 maps but I'll never turn down boost! I'm always itching to turn it up!

That's what I'm going to do. Hopefully I can get lucky enough to find another motor.

i was on my account looking at wrecked and totaled 370's with intact motor and transmissions to see if it would be cheaper to go that route for spares lol

Not a bad idea. Yank the drivetrain and try to part out whatever is left. You would have to get the car for dirt cheap though.

prices arent too bad for some of them. my favorite one was a convertible that was completely burnt from the rear end to the dash. engine was perfect lol

I understand where your coming from that's the reason I said your post was a little bit misleading. What your saying here is very true good install and a tune can go a long way.

It comes down to if he is going to be driving him self crazy worrying if its going to blow up or not then build it.
