Well he says his motor is .040 over, so its not just bolt ones. While the added 7 ci doesnt make much difference, in some cases the little overbore can help unshroud vavles and see decent gains.

Sweet post! I don't really think those mods (Aluminum heads, rebuild) become that big of a factor with that cam, and intake setup. He probably just blew up the original, ya know? 
Good for him. It's all about combo- and he's running faster than a lot of guys with more hardware.

Well, basically it's still a stock Vette L98, granted it was bored +.040" maybe blown up at one time. The heads were basically just cleaned up, as they should've came from the factory, one reason late models like LS1's make more power...(cleaner factory design.)BUT:
*stock cam
*stock computer
*stock Vette heads
*stock style TPI
*Caty. convertors
Like he said, basically a Vette spec L98, TPI with all of the bolt-on tricks he could think of..
I gotta say, "Hats off!"...
I probably could've went faster with my set up, but I could'nt get the traction I needed, still spun like 30-40ft even on my best effort ET...

Nice times but like others have said, its not a true bolt on car.
Bolt ons are anything that doesn't touch oil.
Fastest "bolt on" L98 I know of is Mad Mic's 'Vette. I believe he running 13.0-13.1 now. Mainly does it with a big stall converter because his mph isn't that high.
Fastest bolt on LT1 I know of is 12.2. That car is now running 12.0 with 1.6 rockers added.
Fastest bolt on LS1 I know of is 11.5. Another car with a huge stall.
Anytime you run in the 12's is a plus

91 GTA Ramair2, you must be buying some real "Beaters", I tore my motor down a 180,000miles to freshen it, it spec'ed out Great!
And if normal maintanance is kept up, they hold up rather well!..The only thing I've done is replace door bushings b/c of the long heavy doors...
I've beat on this Iroc for Years!(4years)on the street and weekend trackin'...it's been like a Timex..."takes a licking, and keeps on ticking"..
(this is what I do, you may or may not but..)
You MUST run synthetic oil, which I change every 7500 miles, but the filter once a month and add what's lost...I've revved the begesses out of it without a sound of resistence..
DON'T run it while low on tranny fluid, even a quart..
Fix any and ALL leaky gaskets..
Flush the radiator system with Vinegar every year..
Use an oil squirter and use motor oil on all of your hinges, locks and latches, NO GREASE!..
Keep it waxed to fight rust..and fading
Any unusual noises must be dealt with ASAP, while it's still a small problem..
(Nice cars BTW!..watch the Duration on an EFI cam..)

MAF delete?! Running 16's confirms this is a bad idea lol!
I ran 14.9 @ 92 with 3.73's, a shift kit, and a flowmaster on a 120,000 car. Oh did I mention the valves float?
Other than that the valve covers had never been cracked so it was a pretty lightly modded car.
