l48 engine needed
i have a 1979 corvette l48 and i dont think that the engine is truely a l48 also i cant find the rpo #s so i need to know if i can purchase a l48 or l82 crate engine and where to find the rpo codes to verify the rest of the car. Also there is a gap in my front spoilers on the sides between the lower lip and where it is screwed on i need to know how to fix this if i can. thank you

Re: l48 engine needed (battsup)
The way I knew mine was a real L-48, is that it had zero power and generally felt like crap...
Nevertheless, I had (and still have) real L-82 badges on my hood. And these flat out scare the crap out of every squirrel I encounter.
You cannot buy a crate L-48 or L-82. If you think your engine is not original, and you desire this, you can try to find a block or complete assembly from a donor Corvette. Most likely, you'll have to rebuild it, with original parts (intake, low compression pistons, etc.) to truly achieve that L-48 feeling. You know, the one I bragged about (to no one) and eventually cost me thousands to exorcise from my engine compartment.
My advice, is to enjoy your car. If you're afraid it's not a numbers matching ride, I would not sweat it. Few will notice or care. However, if this inconsistency of build numbers drives you nuts, knock yourself out. There are more than enough resources out there to help you with this pursuit.
Good Luck! :cheers:

Re: l48 engine needed (battsup)
For the engine: Check your VIN. The fifth digit will be an 8 (for the L48) or a 4 (for the L82). Then look on a flat section of the block (facing up) at the front passenger side of the block. You should have numbers there that match the last 5 numbers (the number your car was out of 53,807 for that year) of your VIN.
The RPO codes can be tough. The sheet that list the options for your car may have been put, behind the dash, under the seat, glued to the top of the gas tank (common & sometimes difficult to get to and get off), or somewhere else. That sheet is the only way you can really tell what options your car came with.
If you looking to find out how original your car is, there are a lot of factors to consider. I suggest you do a search on "matching numbers" and maybe even visit the NCRS Web site. Both will give you clues as to ways to find out a lot about your car.
Sorry, I can't help with the spoiler, mine's quite diferent. Someone else should be able to. If you're going to be working on your car yourself, I would definitely recommend the Assembly Instruction Manual (AIM) for your year. It's loaded with very detailed drawings on your entire car.
Good Luck & Welcome :seeya

PyjamaSam-
How did you get your peak HP below your peak tq? that's impossible!
If you make 192 hp @ 3400 rpm, you should have 125 rwhp @ 3400 rpm as well.

PS I never knew the L-48 could be so bad... my LM-1 "feels" the same powerwise as the L-48, and probably makes 175 rwhp at least... (I think it made something like that on one of my G-tech runs.)
