Well ive got a 85 camaro 345 hp at the crank on the dyno. Ive got 4.10's in the rear with a 5 speed. Susp. is stock and so if everything else.

What E.T's Should I be running with these numbers??


Thanks,

 

345 hp at the crank from an L03? That took some work...

If that motor is really making that power you should be capable of easy low 13s with a good launch.

 

ITs a 350 Crate Engine In one of my other cars.

 

I agree. If you hook up low 13's.

 

The lower side of mid 13's.

 

low-mid 13s at around 104 assuming the car has approx. 3500 lbs raceweight.

 

Just out of curiosity, what tranny are you running?

 

345 is close to 300whp. it takes about 240 to go mid lower side of 13's with good tires. more like 260ish to do low 13's on slicks and good driving. with 300whp, and 3500lbs, i can see u doing high 12's if you hook great on slicks. street tires is lower mid 13's

 

With TBI you must have some crazy friggen torque.

Enough to put a turbo diesel to shame ahaha.

 

Your et will be directly related to your traction. You have the power for very high 12s to mid 13s. I dont however see you going any lower than mid 13s if you maintain reqular street tires.

 

Im Running A Stock T-5.

And Yes I will Be Purchasing A Pair Of Drag Radials To Throw On My Stock Rims.

So High 12's to Low 13's is where ill be running Most Likely?

Also Ive got the Stock Heads And Exhaust Manifold On Their Now Is It Worth The Money To Upgrade To Better/Alum. Heads And Shorty Headers?


Thanks Again,

 

Why are you capitalizing each word?

 

Because I Like To. Is It A Crime... Anyway Back On Subject.

 

I would LOVE to hear what motor you have to get this kind of power with stock heads and stock manifolds. Someone mentioned L03, and if you think an L03 with stock heads and manifolds and bolt ons has 345 hp and will run 12s...

Your going to be very disappointed.

 

It's not a crime, it's just really stupid. Good luck with your car.

 

I think he mentioned this particular engine is a 350 crate fitted into another one of his cars.

Or, wait...

I Think He Mentioned This Particular Engine Is A 350 Crate Fitted Into Another One Of His Cars.

K, good.

 

Thank You... Its A 350 Crate Thats In My 85 Camaro. If You Read The First Post You Would Know This

 

Ahh I see that now, missed it before.

If its a 354hp crate motor, Im not sure if those numbers are rated with stock manifolds or not. Figure 290-300 rwhp through the 5-speed. Those numbers should be good for 12s with a decent 60' and a driver mod.

 

Once Again My Buddy Dynoed The Engine. Thats What Its Putting Out Its Not What I " THINK" Its Putting Out

 

Since I see you're probably gonna race it, i strongly reccomend getting that T5 rebuilt and beefed up because its not gonna hold up to a lot of torque. It might last for a month, but theres a reason GM never used them behind 350s.

 

Yea Im Going To Run It Till It Blows Then Swap In A Freshly Rebuilt T56 That I Have

 

That works then

 

a t5 behind a 345 FWHP motor with sticky tires isnt going to last long, if @ all.

 

he just said tho hes gonna run it until it blows, then swap in a rebuilt T56

 

I wish I had a t56. Hell, I wish I had a t5. Jesus...I wish I had a 350 motor.

 

so your sayin that motor dyno'd 345hp with stock style log manifolds??? DANG! with any type of header your lookin at gaining 30-40hp easy.

 

If you're lookin at headers, go long or go home

But seriously 345 fwhp with stock manifolds and you'll see a big gain with headers.

 

Some dyno numbers at the wheels would help too...

 

Stock FACTORY heads? How the hell did you accomplish these numbers then? Heads and headers are DEFINETELY worth the money on this engine.

The engine was obviously not ran on the dyno on those stock log manifolds (im assuming, bc i dont see any reason why it would be) So definetely get yourself some longtubes ...

 

No It WAS Run On The Dyno With The Stock Heads And Manifolds. So You Guys Think The Heads And Manifolds Will Help Out alot?

This Is What The Engine Has In It: What Will Be A Combo That Matches This The Best?

well if you have compcam pushrods, lifters, 3 angle valve job, milled & magna fluxed, and whatever else you have done to them, then they obviously wouldnt be stock factory heads like you said. It might be the factory shell, but everyone is thinking you're saying that they are stock.


edit for: left out a word.

Well obviously you didnt run different heads on the dyno then you plan to run in the car...

ls1's usually pick up around .5 seconds in the 1/4 with longtubes, and your in the same power range,or close enough.

 

So You Think The Heads Are Fine? Just Get Headers? Should I Go With Shorties Or Long Tubes? And Why?


Thanks,
