I here all these differing opinions about whether or not the lt1 in the camaro is different from the lt1 in the corvette. I know some of the basics but what make a corvette lt1 better than the camaro lt1? And what are the differences? And can these differences be "modified on the lt1 to bring it up the the corvette standard?

 

the only real differences that i can think of off the top of my head are the corvette LT1 block having 4 bolt mains and the camaro LT1 block having 2 bolt mains, and the corvette having a more free flowing exhaust (intake too?)

 

is 4 bolt better than 2????

 

4 bolt mains will handle more HP and will better handle the stresses of running 400+HP .

 

engines have slight differences nothing really major

vette is a better performance platform than the F-body, better suspension, IRS and more aerodynamic. Not to mention the nicer interior

But for the price the fbody is a better bang for the buck.

 

Is the 4 bolt the only thing different with the engines or is there something else. And what exactly does a "bolt" accomplish in the engine

 

The "bolt #" is how many bolts hold the main blocks which keeps the crankshaft attached to your block. If you look at a stripped block from underneath you will see the bolts. If it has 2 bolts, it's a 2 bolt block, if it has 4, a 4 bolt main. More bolts=more strength. Intake exhaust and 4 bolt mains are the only difference of LT1 vettes that I know of.

 

There might be a slight difference in cams-nothing major.

The bolts refer to the number of bolts holding the caps on the main bearing journals for the crankshaft. 4 bolts would make it stronger and able to handle more horsepower. It does not give it any more horsepower than a 2 bolt main engine. There are plenty of high horsepower LT1's with 2 bolt mains.

 

thanks I always wanted to know that. It seems to be that the corvette lt1 are alway rated higher hp than the lt1. Is that based on the engine or the intake and exhaust?

 

ahem not all vettes are rated higher. the base SS and WS6 cars had 305hp from the factory. thats five more than a vette. not that it matters since we weigh more.

part of it is that the engine does simply make more power, but also the vette in base trim will always be rated higher than the same thing in an f body. look at the power ratings on the LS1 vettes and f bodies. weve dynoed numerous vettes at the shop and none of them have had anything worth bragging about over an ls1 fbody. thats stock though.

C4s have really good exhausts. you can run a true dual system on there which helps out a good bit. their intakes are not good IMO. maybe somehow better than a plain fbody but, the intake system on my formula is way better than that of a vette. there not many options availible to getting more air into a C4. its pretty closed up under that hood.

the differnces are minor. you can easily bring an F body up to the power levels of an LT1 vette.

and for what its worth. no matter how much you might hate working on an LT1 fbody, working on an LT C4 is so much worse. so they can have there 20 extra horses or whatever they have, but itll take twice as long to work on a C4. its not fun. Trey

 

Just wondering, how bad does a LT1 vette , and a 3rd Gen Camaro spank a 4th Gen LT1 Z28 in handling ...

 

What about the LT1 F-Body's versus the LT1 Vettes, how much ahead are the LT1 vettes than the F-Bodys?

 

Hardcore, I wouldn't think that a 3rd gen Camaro would beat a 4th gen LT1 in handling. The LT1 vette is lighter and probably has a little bit better suspension than ours. Not 100% on that, but i'm pretty sure that would be why.

Im not sure what exactly makes the corvettes harder to work on than the F-bodies but the motor is more easily accessible, all spark plugs changable much easier, engine pulls from the top with plenty of room to spare hell the radiator doesn't even have to be removed. The f-bodie's engine is buried under the firewall where a corvette is right out in the open? I havn't seen anything that makes the corvette harder to work on?? Maybe im missing something.

There are ram air kits made for the vettes that pull air in a pretty direct path through lincense plate hole in the bumper.....although for those of us that live in a state the requires front plates that can only be used at the track.

Oh and btw a LT1 vette these days is not a whole lot higher than an LT1 f-body (though yes higher). Its all a matter of personal preference really.

 

lol ok thanks , I thought a Vette would outhandle a Camaro Z28 or SS by a little bit , but nothing to really go in the back room and beat it over ... Then a little bit ago i was in a thread about is a 305 a good highschool car , and some guy was saying that 3rd gens outhandle 4ths ... Got me thinking , And it jsut didnt seem right ... So i figured I'd ask ...
