ok was talkin to a guy wit a 94 camaro this is what he says he has done exhaust, headers, throttle body, intake. LT4 intake manifold, comp cam.. stage 2 jet chip, short throw shifter....I have an 01 Z28 wit a hooker catback SLP flopac and SLP MAF...whats the outcome?

I'd have to say that he has a better chance of beating you if he hooks up. Have a friend with 94 z28 with a cam and full exhaust running 12.7@112 or so.

Correction: He has DR's and his best trap speed is close to 110, so it will be a driver's race.

I am gonna have to say the LT1...

Why would someone put an LT4 intake on an LT1 Engine. I thought that it was not a direct bolt on to LT1 heads. What kind of cam

I thought it was a direct bolt on, maybe Im wrong.
IMO though it looks to be a drivers race.

IMO though it looks to be a drivers race, the lt1 will probably pull out first but depending on the length of the race it should even out and then some.

Well it depends on the type of cam. LT1's with cams can mph anywhere from 108-116 on stock heads give or take. If you can find out what type of cam this is, it would be easier to tell the outcome of this race. Because if he has any type of cam that is worth while, i would say that you will be seeing LT1 tailights.

Most likely the LS1.

From what I know...or think I know,....the LT4 intake won't go on unless he has the heads to.

If this is an LT4 car, trust me, it'll beat the bolt-on LS1.

Your gonna be around the same power if it's an LT1 with cam only.

Just do it...regardless of what it is.

BLKWS.6

I say the LT1 will take you out of the hole and if the cam is worth its salt he will keep his lead.

I know my bone stock LT1 even with an A4 and 2.73's would take a similarly equipped LS1 out of the hole rather decisively. (bastards always got me by 50 mph though, which is one reason i sold the thing and went 5.0 )

Because of a non ls1 driver. That low down power out of the hole is nothing but a myth. Look at some ls1 dynos and compare them. Than compare the 60' marks.

As for the race in general. Everyone who has posted about the lt4 intake not bolting up to the stock heads is correct. So if he does have different heads and a cam, the lt1 will win. If its just a painted version (lt1 intake painted red to look like the lt4 intake), the ls1 is going to win.

Yes I've said this to them in the past. I think they've only ever raced ONE LS1 and possibly only once or so. Driver is the most lkely cause I think.

And yes LS1's make trmendus grunt down low stock. In fact 90% of the torque is made by a mear 1500rpm. And by 2500rpm (where the LT1 PEAKS) the LS1 is producing significantly more lb ft.

lt1maro

Why dont we find out what cam is in the car first before we just start handing the win over to the LS1 guys. Geez!

BLKWS.6

Maybe you are right about the driver part, yes, it was only 1 race, Hrmmm...I will look at a few dynos. At any rate, the LS1's I have ridden in feel more peaky than my LT1 (maybe b/c they have the same down low and more up top adding to the sensation, i dunno) At any rate, We had a ported head/cammed/full exhaust LT1 95' Firehawk at the dealership I worked at and if this guy's car runs anything like the firehawk we had did he is going to pummel and pillage you. With no special powershifting or anything we could keep that car spinning the 275 meats up to 85 mph where we let off. DEFINTELY more juice than a exhaust/LS1.

300bhp/ton

Yeah with the right mods an LT1 should just fly.

I think you are right about the sensation thing. An LT1 has a big whollop down low, like being slugged in the face. Where as the LS1 keeps up the pace to almost the red line, like some one running into you and just pushing.

More power but porbably less sensation.

Anyhow it also means props to you, as you where evidently out driving them

This is an dyno graph for the LS1 and LS2. Remember this is ENGINE bhp SAE Net and not rwhp. But see how much lowend grunt the LS1 has.

NOTE: the scale on the left (lb ft) is a little odd and makes it look like a steep in cline in torque. But it isn't it's just how this graph displays it.

According to the chart the LS1 is making over 340lb ft by 2500rpm, compared to the PEAK of 325lb ft for the LT1 at 2500rpm.

BLKWS.6

the LS2 is bigger though,...im not that impressed by the gains it has over the LS1, but i suppose it is still better, oh yes, mad props to the CAI only LT1 with 2.73's pulling hte LS1 with exhaust/tuner to 50 THX I think he took of WEAK (yes, he knew we were running em)

If he has the Lt4 INTAKE he needs the heads to go with them. It wont bolt up other wise. so find out for sure And he has a Cam & Car is Tuned correclty he will WALK you i would SAY
