lt1 vs ls1

[Injuneer]

that thing is super sweet..... big bucks, but sweet !

It's only $45,000












..... plus YOUR LS2 GTO.

One thing I will say for the LT1 - parts are MUCH cheaper as most of the parts are interchangable to a SBC. An example - pushrods - I paid $149 for a set of hardened pushrods for my LS1 - per a member of my club he paid $33 for a set for his LT1

Blower vs. Turbo

Blower vs Turbo, Well that started something. Personally I think, and the fact that they won't allow them in pro mod racing the Turbos with computer controlled fuel injection are your more powerful setup. Mike Moran ran 239mph in a Turbo Pro Mod exibition, blowing the Pro Mod mph record away, and they,(NHRA), would not allow him to compete. There is a Twin Turbo kit available for the LT1 that promises 800hp at the low boost setting, and 1200hp at the high boost setting. I purposely did not put forged pistons in my motor for fear that I would get stupid, and do something like that. The Stock drivetrain would give up the ghost in a heartbeat with that kind of power. Even if you beefed that up the chassis would twist like a pretzel. My former drag car, a professionly built chassis by Don Ness in 1990, would only take about 1400hp before it would twist, and not take any more power. The result of the twist was a car that would always turn to the right, no matter what you did to the 4 Link or pre loads. Friends of mine who raced heads up experienced the same problem. So even a full chassis car will experience twist if not set up to handle extreme power, imagine a stock body, even with a roll cage.

It depends on one thing, IMO... Do you like the look of the LT1 birds and raro's, or do you like the look of the LS1 cars? That's what it's all about. If you like the LT1's, get that, and the 3000 you saved buying the LT1, do some head work, mild cam swap, exhaust, suspension, etc, and you'll be beating 80% of what's on the road. Easy 12 second car.

If you like the other car, buy that and you'll have an easy 13, sometimes high 12 second car. Put a few hundred into the suspension and sticky tires and I don't think 12's are far outta reach.

I'd have to take exception to that statement. Ron Duke's unit body 4th Gen CONVERTIBLE is now running in the 7's with nothing more than a full cage and SFC's. A lightened coupe unit body has run 8.08 with a turbo, and claims its still got another 7# of boost available. The convertible below is a typical example, and while it only ran 8.60 with 1,325HP, it had been substantially lightened (down from 3,900# to 3,525#) from the stock configuration. It has no chassis reinforcing of any kind, other than a 12-point cage (that does not continue forward to the shock towers) and a set of low $$$ MAC subframe connectors.

Thanks, Fred... I wanted to mention that. Ronnie Duke, Harlan, and Mike Brown are all going to be in the 7s this summer... competing to see who has the fastest LS1. Their trap speeds are now going to surpass 180

I was there when the trap speed record fell - 178.3 MPH (mid 130s at the 1/8)- Let me tell you that it was obvious they have a LOT more in it. He could not stay into the throttle the whole way - you could hear him getting in and out of the throttle! See Jay you should have come down!!

Full frame

I have not seen the chassis on these cars, but I have seen the chassis on a late 90s Camaro that was running in the 7s' in heads up 10.5 races. The rules in this class stated that the firewall, body, and most of the front suspension had to be stock. Tubular A arms were OK. This car was heavily reinforced with a full cage, and purpose built for the class. The owner stated it had cost him 80K to build the chassis to run this class. I am only stating what he said his costs were. I can only relate to my own experience with Chassis cars & those of others who had the exact same experence I had. I would love to see what is being done to these cars to get them to run these times. I find it hard to beleive that is just a simple bolt in cage. My Beretta would run 4.90's (1/8th mile, about 7.70 1/4) all day, and go straight as an arrow. Step up to more power, say try to run 4.50's, (about 7.10 in the 1/4), and it was a wild and crazy ride. I sold the car rather than beef up the chassis to handle extra power, it is not a cheap hobby, and I was competing with players with much bigger budgets than I had. Previous to the Beretta I ran a back half Nova that had a full cage in it and it was a handful at 5.70 in the 1/8th. If any of these cars get to Fla. I would like to see them. I will not beleive a stock chassis can handle that kind of power.

So all of these guys are lying to you? I realize you may have some drag racing experience but clearly you do not know much about F-bodies. The guys here that you are doubting are not the kind of guys who throw around facts to impress. Brush up on your F-body facts before posting your doubts again....please!!

I thought you claimed to have an LS1 F-body.

Dead wrong. Do some reading (enlightening) over on ls1tech.com and cz28.com. These f-body chassis' are incredibly stronger than most believe.

Call us liars if you want.... I was a crew member and wrenched on the 30th SS shown above. There are numerous pictures of the car, including shots of the suspension and chassis on my website.... little if anything is hidden. The car has a welded in 12-point cage (who said it was a bolt-in - apparently you like to make up things to support your claims ) . The 30th raced at Bowling Green, Atco, Maple Grove, and Bristol, to name a few. It raced in the PRO/Edelbrock Xtreme Street class - go read the rules..... STREET class. Stock suspension, no back-halves, no tube frames.

Believe what you want, but for the others with an open mind, and capable of dealing with simple facts, your 4th Gen chassis will not trun into a pretzel if you subject it to 1,200HP .

Hold up, you own a 4th Gen and you haven't even looked under the car, yet you're using a 3rd Gen to base your opinion on the 4th Gen?? Dude, come off it.

Getting back to the original question, it all depends on what your budget is "dropit". I picked up my 93 a couple years ago for $5k and she's been good to me, just a little belligerent. LS1s are coming down in price, but still more than the LT1. Plus you can take the price difference and use that for mod money on the LT1. Both respond well to mods and both will please you. Hope this helps man. Good luck on your decision

Ronnie Duke's car went 7s back in February on a Florida drag strip.

I know, I have the video of that run on my computer, it's pretty awesome.

However... do you really think the Ohio boys have what it takes to beat out the Michigan guys - Harlan and Duke????

hahahahha... I'll look for a Michigan/Ohio battle anywhere I can get it.
