290 hp??????????? thats low

I'm guessing concessions were made in selecting components to make this motor a direct 350 replacement to work with the stock TBI.

=( =( =(

I'm ok with it. Still a lot better than what is currently in the truck and a great foundation to make more power later.

So they've had three days already...What's the prognosis?

The new motor was being bolted in this morning. I'm hoping they get it fired up by tonight.

Unfortunately, one of the exhaust manifold studs broke. They didn't have time to get it apart and replaced before closing up shop tonight. They are projecting having it finished Tuesday now.

The motor is running!!! Except the ECM didn't like the new EPROM from Blueprint (Code 51), so it is running on the stock 350 EPROM. Waiting to hear back from Blueprint on getting a new EPROM burned and sent out ASAP.

How big of a pita was the install?

 

[Chewy1576]

Had a shop do it so I can't say for sure. Other than the broken stud and chasing down replacements for other worn out parts they haven't said anything about difficulties.
