Engine Rebuild time
Just got my tax refund in, and its time to do an engine rebuild on the old 72 L48. I've been waiting years to do this, and now I've saved up enough to do it. It goes in next week, and I can't wait to finally have a corvette with 300 rwhp! As soon as I get ahold of a digital camera, I'll start posting pictures.

thanks goes out to forum members (specifically lars) for helping me to decide a few weeks earlier on what engine I would build. there's no people like vette people.

Since the car is numbers matching, I've decided to use the original block and heads in the rebuild. The block is a 014 block, that will be bored .030 over, i'm going with brushed rods, and .100 domed hypereutic pistons (Speed pro) with floating pins. The heads are 993, which will flow well enough for the street but they will have 2.02 intake, 1.6 exhaust valves installed. I'm going with a Comp cam with a 280 advertised duration. I'm using the stock intake and carb for now, along with exhaust manifolds, until I can save up a little more money for those upgrades. I figure with a 4 speed, this ought to be a lot more fun to drive then a bone stock L48.
Pictures to be posted as soon as I get my buddies camera.

Corvette Fever did an article on adding 150hp to a L-48 and keeping it correct for NCRS judging. If you are interested I can E-mail it to you. The jest of it was flat-top pistons, Crane Cams H272 cam, a lot of internal head work, and carb rejeting.
When they were finished it went on a dyno: 326hp 375ft/lbs torque

redwingvette--
yeah, if you could send me that article, that'd be great. ted.weiland@gmail.com
mvftw--the guy at the machine shop mentioned that the numbers would be changed after it was machined. When you talk about the pad, are you talking about on the front of the block (CKW letters in my case-coupe 4 speed) or the block numbers on the back (3970014)? I'm kind of a newbie at this, and so i would like the clarification before I send this beast in. Would you happen to know where they indicate that the block has been bored over?
Also, has anybody run into a 014 block that was a 4 bolt main, specifically in corvettes? I've read about it happening here and there on the internet, but I don't trust all those sources (for good reason).

A good machinist can stop the machine before it hits the pad. If the pad gets machined you lost value in your car! I would go this route because a rebuilt engine doesn't mean it's going to run good (only as good as the builder). I would buy this and keep your engine in a crate.
