I'm trying to decide if I should have my matching numbers engine rebuilt (its at 86k) or just save it and drop a new crate engine in. The new crate would throw on another what? 150+ horsepower from the stock engine however I'm not quite sure what would be more cost effective? I would have the engine rebuilt by a corvette specialist or have the new crate installed by a shop, what price ranges am I looking at roughly and how do they compare?
I deffinetly will. Just not sure whats more cost effective at this point. I don't need massive power but you know, some extra HP wont hurt if it ends up costing less then rebuilding the original
I wonder how many people acutally pull the crate motor out after a few years and drop the original back in? Stashing the original motor in the corner of the shop is a great concept, but I get the feeling people are saving them for the next owner.
I think the next guy should get his own motor, so I vote for rebuilding the original.
Thats true, although you never really know. I just purchased the car so I'm in it for the long haul, she wont be sold, if ever, for a loooong long time. How much does it usually cost to have your engine rebuilt? I do realize there is cost of parts and labor for that but am I looking at considerably less costly than buying a brand new crate or around the same?

IMHO, stay away from ebay. Lots of people got scammed w/some of those engine builders. One guy waited 6 months for delivery and never got his engine. Builder went out of business and he lost his $$.
Buy from GM, Scoggins, Jegs, Pace etc....you know what you're getting.
You didn't say what year vette you have or even which engine, but if itit's a 68 -72 I wouldn't rebuild the original. You'll read on the forum here about guys sending their #'s matching engine in for a rebuild only to find that their original numbers were gone after the rebuild.

I rebuild my original engine a 72 base 350 (~270hp crank)
I will keep the old parts to the next owner.
Made full rebuild +40 put new heads intake carburetor cam & flat pistons and get ~400HP, ~400TQ, parts cost ~$2300.
The main thing I know what I put in the engine.

I'm a big fan of rebuilding it myself. The knowledge you'll gain is rediculous. The only problem I think is you are 100% accountable. You can pick up a GM Crate motor, get a warranty and forget about any possible mistakes.
Is it an L-48 or L-82, you've said both.
I'm sure you could easily build 300HP for $2K yourself.
oops. Still learning all this stuff. Its the weaker engine the 175(i believe it is) hp one. I'm not sure I could put myself up to the task of building an engine just yet as I'm still learning all about this stuff, its been a general interest to me but I'm just now geting "into" it. Although it owuld be one hell of a fun project.
well my friend, that is what the forum is for. There is no better way to learn than doing it yourself. Of course you'll have to shop out some stuff, but I really think its worth building up your own.
Go grab Vizard's "How to rebuild your smallblock chevy" and follow it to a T.
I'm also sure there are plenty of guys close to you who know what they are doing and are more than willing to help.
