1. Where do I think they got that number from? Who knows, their a$$ maybe?

2. Why don't you contact the "DOT" and ask them what your car weighs exactly? Or better yet, contact GM.

3. I weighed my stock LG4 as a baseline, much like running down the 1/4 stock also. I wanted to know what mods accomplished what first of all, and secondly I made decisions on what specs (converter, cam, carb tuning, gearing etc etc) I needed based upon weight. I tried to put together a combo that works together, and weight is an important tool.

I don't want to hear anymore of that nonsense about shipping weight or manufacturer's measurements. Truckers often underrate their shipping payload to carry more to bring up earnings per shipment. They do this in the auto shipping industry as well. Many years ago when I first started working at a Lincoln/Mercury dealer, one of my job duties was to inspect cars as they were pulled off the trucks. Nearly every driver asked for routes around the weight station on I95, as they were overloaded - hench false shipping weights. And about manufacturer's measurements. GM rated the F-body LS1 at 305 crank HP. Actual measurements show that to be false. Same goes with the TTA, GN, Sy/Tys etc. Ford claimed 320HP for the 99 Cobra... BS! Look in a 2000 Ford Lightning owners manual sometime. They claim its only good for 14.6@95mph. That is also untrue. I can go on and on, but I'll save you the embarassment. Don't believe everything you read, no matter what its printed on. Especially anything government related.

BTW - I checked my title to see how much my cars weighs. Its shown at 3100 GVW. I know that's not true because I have weighed my car. But according to you that must be correct, so my car must also be lighter than your 4th gen right?

It's obvious by now that you have no intention of weighing your cars, and that you'd rather read a piece of paper. One day you'll wake up... And I'm done with you

 

Actually.. it looks like the LS1 just plain flat-out passed him at the end, but either way that 305 did really good :thumbsup:

 

A cammed/geared 305 may run close to a 4.6 if its stock. The 78 was a heavy car though. I think, depending on the size of the cam and a few other variables would be needed to make a determination.
A stock 305VS4.6 wouldnt even be a race. The 4.6 would win fairly easy.
Some of the later 305 cars made it into the 15's..WOOHOO!

 

^So what about a cammed 305 in a '85? Amongst intake and exhaust?

 

305's were breaking into the 14s totally stock as early as 1983

 

^Thanx for defending the cause Robb
Which engine cars were the 14's? And were they proffesionaly driven?

 

Hmmm.....I don't know....1983 L69 Z28 running high 14s? I sure don't remember that being the case - not saying it isn't possible or didn't happen, but I'd like to see some evidence.

 

And plenty of stock '96-98 GTs had a hard time getting into the 14s. That 305 has a chance.

 

actually you guys are both wrong. the L98 is 2 bolt main. i think even the L98 vette was 2 bolt. the lt1 vette and lt4 anything got 4 bolt mains.

they are rated at 245/345 stock at the flywheel. period. gm has NEVER rated their engines at the wheels. but some make advertised FLYWHEEL numbers at the rear wheels.

my car made 227rwhp and 357rwtq with a catback, custom sh*tty cai and a rebuitl tranny. mods were: bassani catback with open cutout, pvc CAI, rebuilt tranny with POS shift kit, vette stall, vette servo. truth be told i doubt i have any of those tranny mods because its in general a POS.

 

Hm.. that is weird because my friend w/ an 87 IROC said that his L98 had a 4bolt main Well, he said he THINKS it did, but he said he isn't positive. Camracer.. what year/model/engined f-body you have?

 

i think a 95 or a 96? 96 was first year of 4.6?

 

Car and Driver 6/83. I have the issue around here somewhere. If I locate it I'll post a picture. Just imagine a stock 305 Camaro running high 14s stock, and smoking a 5.0 in the process

 

Please do post it and make a believer out of me.

And 3rd Gen's of that era did occasionally beat the same year 5.0s, but it was the exception vice the rule.

Bob

PS....I have a MM&FF that has a stock 305 3rd Gen running 14.4, but it wasn't an 83.

 

They started that body style in 94 (I just looked it up, lol).

Bob Cosby, what year, engined, and trannied thirdgen did you find w/ a 14.4?

 

I'd guess a 90-92 1LE LB9 (305 TPI) 5-spd. Car Craft managed a 14.3 with a 91 L98.
