And what am I supposed to be thinking of before I speak? I dont see anywhere where I put false or misinformed info. Maybe you should try and not be such a smartass

Re: 305 vs 4.6.. who would win?
85-305 calm down man i didnt see him being a smart *** being anyworse than trying being a know it all, when this whole thread is about giving you advice. Now we need to establish one thing, it was earlier noted that someone refered to the L98 in the f bods the same as the one in the vette, They are NOT the same, one has alluminum heads and higher comp(vett) the other f bod l98 is an iron head "version" of the vette motor. L98s in the thirdgens werent putting 245hp at the rear wheels. Mostf bod l98s barely put out 220hp flywheel stock. as opposed to lt1s 285 (underrated) stock fwhp, again i see no one keeping an open mind

L98 reached at peak in with a g92 car at 235hp in 91/92 models correct??? SO how is that ne where near LT1s underrated 275hp? Your also rigfht when you said you can get a nicely equipped thirdgen for about 3500/4grand, But if you mean in the eyes of something like an TPI iroc or TA its going to be beat. I am not bashing thirdgens but keep an open mind, dont be afraid of change 
It's called scale, try it sometime...Later L98s 91-92 were rated at 245HP (Pontiacs 5 less), and commonly dyno around 210rwhp. Early LT1's typically dyno 15-20 more, with a good deal less torque, even though the curve may be flatter. This is almost completely offset by the weight difference BTW. There's a local dealer here selling 91 L98 Z28, with 80,000 miles, asking price on the window is $4500. Car is completely stock, a true L98 car, and is as clean as they come.
85_305 - The only 4 bolt main L98's were found in Vettes. And you'll need a bit more than a throttle body to run 13s stock (on average). And those numbers on Thirdgens site are manufacturer rated, which means its crank HP. No manufacturer ever has quoted wheel HP, and probably never will. Claiming WHP numbers is a recent trend as chassis dynos have become more popular, giving birth to these kind of myths.
Stock examples are very hard to come by, but I've witnessed a stock L98 91 Formula turn a 14.2 back to back to back. LT1's that night ranged from 12's modded to mid 14s, driven well.

Re: 305 vs 4.6.. who would win?
Best I've ever seen an L98 3rd Gen run was 14.2 @ ~98 mph. This was back in 1990 at Great Lakes Dragaway in Wisconsin (LOL - 15 years ago!). The guy sweared up and down it was stock, and from my brief look over, it certainly appeared to be. He was icing the intake, but that doesn't make it modified.
LT1s will easily produce more HP than an L98. 200-210 is probably a good average RWHP range for an L98 (A4, of course), while 230-240 is a good average for a non-SS/WS6 A4 LT1 (M6's will dyno somewhat higher).
Low-rpm torque simply doesn't matter when it comes to acceleration, though it can make a car "feel better" on the street.

PS....as posted earlier, the title on my 2004 Cobra says it weighs 3114 lbs.
That's not real likely - though I certainly wish it was accurate.
