Supposedly the lt1 has lt4 heads and cam or something, but full bolt ons, weight reduction, 4.10's, tire, driver mod.


5.0 has full exhaust, boss intake manifold, jlt cai, bama tune.

This lt1 walked my ls1 camaro (that did 12.7 @ 110 mph), so me and the 5.0 owner are still trying to figure it out.

The LT1's with a decent head and cam combo with full bolt-ons are no joke they can put down some decent h/p to the rear wheels. Impressed with the LT1, hanging with a full bolt-on 5.0 Mustang. The lt1's don't get enough respect with the mighty LS1 around.

I was impressed by the LT1. I saw the thread and I was like oh no this 5.0 is gona rip the doors off this lt1.

Strong running lt1. Bama tune ftl though

Good running LT1. I thought I was going to be bad..... Don't forget , that can be over the 400 rwhp range with H+C.

big hammer

lol what gears does the lt1 have? 5:13's?


good running car though.

To much gear in the lt. Runs good just to much gear. A buddy had a lt that went 12.1 @ 114 with a very mild rebuilt with used pistons/ring lt. Car was not really even tuned right and only had shorty headers. He did have 3.90 gears though which don't seem like much difference but it is.

LOL....you beat me to it. You replied while I was typing.

he should throw another inch of tire under it and run it again. would be interesting.

Hey bama is the **** lol. I see you got a drive shaft how you liking it.

HioSSilver

Not at all.....that would just add rotating and slow it more. Great for traction but **** for accelerating.

SCalla1384

Me? I like my shaftmasters ds. No issues.

Bama sucks. They don't disable clutch protection, torque managment. I guarantee with the boss intake he's dropping power after 65-6700rpm because they don't adjust the vct.

Dont forget making less power with more aggressive tuning.

But on another note. Great running LT car. Agree it either needs another 1000 rpm of power band or drop some gear.

LOL! Can't be… Car runs good and we never saw it's tail lights. So that's quite impossible.

Plus, the body looks pretty straight, … another tell tale sign.

Taller tire will effectively lower his gearing. It would help him since he seems to have way too much gear. That doesn't seem like 4.10s unless he is still using stock shift points/short shifting - 4.10s wont run out of gear that fast unless he is making WAY more hp then a bolt-on LT1 should.

Still not a bad running car if its beating 12.7 cars with bolt-ons. FWIW my 93 did 12.8s with "most" boltons (still on stock salad shooters, no EWP, through an exhaust). Probably had 12.5s in it but I jumped into more mods before I optimized it. I feel that high 12s should be average for a good running bolt-on LT1 car. Some will be a lot quicker(record for a bolt-on street car is currently 11.4), but some a lot slower (I've seen bolt-on LT1s run what my 93 did bone stock, 13.9).

They are basically high compression SBCs, so it's king of silly that they get so much hate but I kind of like it. Makes it easier to hustle when people see its "just an NA LT1" .

::edit:: BTW, prepare for the shitstorm from the slow 12 second LS owners - "He was spraying", "It's really a stroker", "I heard it weighs 2800#s", etc

Hios point is that more tire is going to cause more drag. Typically with racing, you want to run the smallest tire that will get you to hook and then gear it accordingly.

For example: Which do you think is faster assuming both cars hook. (Also... the steeper the gears, the more friction. The more friction, the more power is robbed.)

Same motor/trans in both cars.

4.10/28" tires
3.73/26" tires

(im ball parking without doing the math... assume mph per gear is identical)

Which is faster accelerating?

To me... its a no brainer which one you should run. Less tire...less drag... less gear...less friction. More tire....more drag....more gear...more friction

Ideally he will either raise his shift points, put less gear in it, or both.

The assumption was to just a quick rematch with a taller tire though ("Throw another inch of tire under it"), which I agree with. It's a "bandaid", but a 1" taller tire will help nonetheless without having to open anything up. It wont hurt him like insinuated.

If he had the proper gearing then of course run the smaller tire.

Ova was this you? JK! Strong running LT, I would have loved to see some dig runs though.

You're pretty close on the gear figures. 4.10's with a 27" tire is about equal to 3.90's with a 26.
Problem is I try to avoid thinking in "bandaid" terms. LT guy maybe could turn it harder. But from what I've learned about lt's is they should not be turned very hard on the stock bottom. Tolerances are to close according to my bud that built one.
