Alright. im deabting getting a 98 ls1 for my 67 camaro. and before i put it in i want it to sound and run amazing.

im putting in a 224\230 cam. but i have no idea what else. i wanna be making about 330 horsepower at the wheels. so about 380 under the hood.

what engine combo should i do? and i dont wanna spend to much money. and im tryin to hold off on the heads. i also want this to be able to support a 100 shot of nitrous.

How much Gas Mileage will i be getting with a good 380 - 400 horsepower combo. im running 360 horsepower right now outa my 350. but i only get 7 mpg.

What transmission are you thinking about going with?

With that cam, I think you'd have to really try to not pass 350 rwhp..even with the stock exhaust manifolds. With some long tube headers, an LS6 intake manifold, and a ported TB, that should be good for close to 400 rwhp with an M6. But you're probably going to run an A4 something, so 380 rwhp+ with that setup and stock heads.

Gas mileage obviously depends on what tranny you run and on the weight of your car..but I doubt you'll see anything close to 7 mpg unless you keep the RPMs at 4000 everywhere you go.

You could have close to 350 rwhp with the stock cam and heads...just LT headers and the basic intake/exhaust get you pretty close.

The 100 shot of nitrous should not be a problem.

This might cost alittle more, but would be money well spent...

G5x-2 cam
Long tube headers (SLP OR FLP i would go with)
And then your choice of exhuast....

that should be around 380RWHP.....

If i were to do some things over I would have done that
(mainly the cam)

330 rwhp can be easily reached with headers and a few bolt ons..

and your getting a cam right.....that will defintly put you over 330 rwhp

i have a th-350 tranny. its the same tranny i have now. and i got 3.73's and a eaton posi.

so if i get a nice cam, lid, long tube headers and i got good exhuast right now. 2 1\2 inch. h-pipe with flowmaster 2 chambers.

itll put me into 330 rwhp. and then if i throw on a 100 shot of nitrous on top of that i would be perfectly fine?

How are you adapting your TH350 to the LS1? You should be able to hit 330RW without headers, LT1s can do over 300 with a mild cam and stock manifolds, they just run alot of exaust duration.

I'm putting down exactly 325 at the wheels, and I'm doing it through stock manifolds. Get an LS6 intake and some basic bolt on mods and you will be close. Throw on some LTs, and you will be there.

This is not a 67 Camaro...it will be very hard to run an H-pipe...as for the tranny, BMR sells a convertion kit...but I think the 4L60E is fine for JUST 330 rwhp. But IMO the cam would be last, get some air in that baby...then headers...then tuning..then cam. In my experience tuning is very important...even without a cam. Besides you'll need it anyway when you do a cam swap..

Good luck

Where? I cant find it anywere on BMR's site. If they sell it though another retailer, then let us in on who. I want to get rid of my 4L60E and throw a th-400 with a hurst dual gate shifter on. Nothing like ratchet action....

ChrisLS1Bird

no..it will put you WELL over 330 rwhp. I think you'll have around 380 rwhp with that setup.

If all you want is 330 rwhp, you don't have to do much work. Ahh yes..the wonderful LS1.

And I don't think a 100 shot of nitrous would be any problem. Many guys regularly spray 150 hp shots on stock blocks.

Uhhh.. what are u talking about buddy. its sittin in my garage right now. thats all already done to it. the h-pipe wasn't hard at all. took my muffler shop buddies about 20 minutes. and they only charged me 15$

What about an Lt1? what would i have to do to get that around 320-350 rwhp. Im not forsure going ls1. its either ls1 or lt1. just a matter of what i find.

and i heard that the tranny mounts right up.

Dr.Mudge

If you dont care about powerband, a 230 intake duration cam on a stock headed LT1 with headers etc will turn over 350 RW, but not by much. What gear are you going to run out back?

LT1 is alot cheaper, but the heads flow alot less stock, yada yada yada, whole different ball game. Cheaper to obtain, cheaper to program and so on.

shocker45

im runnin 3.73's and a eaton posi outback.

how much would it cost to get that much out of an lt1. and what would i have to do?

and where would my power band be shot with a 230 cam?

check out the sig and my mods.

Dr.Mudge

Low end will depend heavily on your programming ability with timing, the gears will help obviously.

Parts are basically the same as any other roller cam SBC, so do the math, cam, springs, roller rockers, new valve stem seals and etc etc along with your headers and programming gear.
