ooo...that was rough. lt1 cars don't get enough time these days to really be perfected to run like ls1 cars. there is just no r&d in the lt1, because they're seen as outdated. ls1's have better heads for the cams ground for them....but i still say that my lt1 gets more heads turned by ls1 guys then anyone.
i thought about the ls1 swap..but im confident in my lt1..if i ever get it running right.

 

The LT1 was factory specs with a Hotcam. It ran good for what it was. The LS2 I am building is a Stroker with Heads that outflow 95% of the aftermarket, and it's goin to be high compression with a nasty Cam in it. Do some research on that setup, it's getting into the low 11's, high 10's very easily on all motor.
Find an LT1 without spray, just Heads/Cam doin that for under $6500, cause that is my estimated cost.

 

That's all your shooting for all motor? Low 11's / high 10's?

I'm well under $6500 at the engine with my itty bitty 355 w/ LE2 heads.

$1500 into the shortblock (forged minus the crank) + ~$3000 in heads/cam/valvetrain.

Already did low 11's.. shooting for high 10's this winter No spray, all motor... oh, and a mail order tune

 

Don't really care about your setup and your post is completely irrelevent. Thank you for whoring out your setup even more, because everyone in this thread cares.

 

ya but the merv is doing a cam that is used in stock cubic inch motors...and similar to the 306....so in his big 402 its like running a 305 in a 383, if he did a upper 240 duration cam, and if he did a 4400 stall and 3.73 he shouldent have a problem getting mid 10's on motor full weight! WITH STOCK HEADS! (which flow over 330 out of the box, the le2 are 1500? these were only 800)

 

Money spent is money spent, that's not the point of the answer.

He asked a question. "Show me an LT1 that has done it for less than $6500"...

I answered it.. I've done it, for significantly less. Big whoop, my cam's duration is in the mid 230's.. it ain't no monster and it's 100% drivable.

 

o0o didnt read that...i almost did a 383 le3 and was considering a solid roller, but lloyd and i talked a while, and withoug a single plain i dont think i could have reached my goals, and then i got a ls1 for free so i said screw it, might as well, and its incredible how stock ls1 will hold 250+n20 and cam only running 10 and making 400+ rwhp, anyways i had a cam only daily driver lt1 running 11's on motor with a off the shelf cam and mail order tune
cc306 fuddle 3200 and 3.73, pcm4less tune = 11.90 all day
125 shot=10.8 all day
driving it = 25 mph freeway about 18 or so city keeping your fooot outa it, was a great setup

 

y not just build a sbc with a dist. and use the pcm for fuel.
sbc heads are flowing more than similar lt1 heads, and so many manifold options. like the super victors and jr.'s. i guess thats what i would look into if
i was building a single digit "lt1"
i just see alot let hassle with using an sbc
0.02$

 

Read thread please.. irrelevent posts are getting annoying.

 

yea...javier has a nice setup..im on like le1 equivalent heads and i have like an le2.5 cam. also at around 3200 raceweight, (no heat, a/c, carpet, etc) with the big stall and full suspension. id love to go 11.3x on that.
the guy with the joe o cam went bottom 11's..and it was drivable as well..get a custom cam like the 847 with more low end..problem solved.

 

Appreciate the help from all of you. Anyone have any tips they'd like to contribute that they wish they would have known when they started racing?

 

Maybe some of us are throwing out ideas and what we are doin based on the research that we have done..


That post answered part of your question from before, it had alot of relevence to what we were discussing.
You build your ****, and I'll built my ****, and we'll see what it does..

 

best advice...find a cam/tranny/rear/tire combo that has worked. many of us have redone our setups over and over. do it right..but do it once.

 

It's all in the parts combo, no matter what you have. Even then you got to get it to the ground..

 

I copied javier97Z28's old cam only "503" set up in my daily driver, stock full weight w ac and two bad o2 sensors (slow 60ft from the bog 1.8) ran a 12.4 but now its runnin good so im lookin for low 12s high 11s.

 

yep...get a cam done with the right rpm range. get gears for that range, and a stall for that range. get a good suspension and get an awesome tune..and have fun.

 

back in the day i had a cam-only lt1. i used the cc503. super street friendly made decent power. 11.70's on motor and 10.70's on a lil 150 shot.

 

I post that I'm building a cam only LT1, and you throw in a post trying to ***** out your LS2 setup. What does "I'm building an ls2 with heads and cam" have anything to do with me wanting to build a cam only LT1?

If I built a big stroker with high flowing heads and a big cam, I'd be shooting for faster than what you are. I'm glad you're excited about what you're about to build, but no need to post it in every thread made in the LT1 section.

 

I leave it to the quote to tell why I made the suggestion of a LSX based Stroker...I read Cam only, no mention of any type of Engine...my build is Cam only..

I mention my plans around here because I am sure that there are several people interested in this sawp, and I have got a working way to get a LSX into a LT1 Car..

It's all good, do what you got to do..

 

Hey guys with the cc503 what rpm are you shift? Anything over 6k makes me nervous on stock bottom end.
