I have a 64 ChevyII Nova that is Tubbed, Narrowed fully 12 point cage car. It has Lexxan all around, fiberglass Front removable cap , trunk lid is glass and doors. The car weighed 2300 with a big block chevy.

I bought a 6.0 lq9 that is new and have 232/234 cam to put in it from cam motion with stock lq9 heads and 6.0 intake. every thing is on the engine( sensors, water pump, alt. , injectors etc) but I dont have a computer and harness.

I have Efi live to tune it but am thinking that instead of running EFI , that this may be a good car for a vic jr intake and carb.
Fuel milage is no concern as this car is for drag only and just wondering which will make the most power?

I will port the heads later but for now it will be cam only as I believe this car would run 10's with a stock lq9

I want the car to go low 10's and think cam only this car will do it as I am dropping a couple hunderd pounds off from the big block


which is it Carb or EfI?

EFI, period. Vic jr + 90mm tb or get a 4150 style tb.

will efi make more hp and tq or are you just partial to efi? I like it better as well but for a race car , will the efi be quicker?

its a drag only car carb it and put a regular distributer in it but if your going to try to keep any electronic on it go efi w the carbed intake

What is wrong with the MSD box that comes with the intake kit?

hell i like efi because easier to tune and reliable and i love the throttle response, plus the elbows look cool. to me i just dont like adjusting the carb every time you go out to play.

If I were looking to rejet or retune every time out then yes the efi would be easier. I am going to bracket race so finding a jet size that works most all year long will be not that hard. I may loose a few hp in certain weather but it should still be consistent.

I may have a computer and wire harness set up for it , if it is still there when I am ready to buy then that will be what I use. If not , then I am thinking carb.


I know cam profile for the f14 is not the best choice for a vic jr intake but down the road if it does not run low 10's or better I can get a cam for it.

true, your reasoning sounds good to me, whatever you do let us know the numbers abd how it runs. for the weight your running, it should be fun.

EFI will probably make slightly less power than a carb, but it will be quicker down the track, give you many more variables to control, and get you more looks in the pits.

SO far , it is going to have a 4.30 gear with 31x13 m/t slicks . Bte 5200 stall(8") and the f14 cam to start. Stock 6.0 heads that I may mill for a bump in compression but other then that a speed density tune with EFI live.
I figure if guy's on this sight can get a 2900 lb race weight with stock long blocks to run low 11's with stock cam then this thing should have no proble getting in the low 10's or high 9's with either setup . I am going to start out with a stock cam untill the car is up and running and then change cams after atleast 1 track outing

I do beleive with the stall I will be running that will be the best when I get the heads for it. To start I would run the 750 with the stock heads .

i respect your originality and since you will be using a close to stock efi motor then use the efi to keep the flow of the idea you are going......personally i would put in a 510 or 520 motor, all bore short stroke in a dart big block with Dart 360 or AFR 355 heads, 13-1CR and a big nasty solid roller Thats whats goin in my 72' Nova, the more simple the set-up the longer it will last!

if you have the money and know how, get EFI, you will make slightly more peak power since you can finely tune it better and easier than a carb and power under the curve can be finely tuned way better than any carb. A carb is a lot more simple to set up and cheaper, and can be as consistant but you gota stay on top of it, rather than let the computer do the adjusting for weather conditions. However if you decide to use forced induction, change cams, heads whatever, its soo much easier to tune the computer than to mess with the carb.

I have a little experience with the msd/carb set up. I bought a mustang coupe off of a guy in chi town. And when i got it, I had the hardest time getting it running. It turned out to be that I had to spin the **** out of the motor to get it running. I finally got it figured out and it ran great. I pulled the motor to put in my camaro and I'm building a 383 with afr 205 heads a T-rex cam and putting the vic jr intake back on it with the demon 750 carb.
I think it will be a nasty combo when up and running. Search under my sn and you will find my thread in the drag section. Lots of pics.

I think a lot of guys are scared of the carb set up because they don't fully understand them and how to tune one properly. I'll admit, I'm not very good with them, but my buddy is and I'm willing to learn. It will rev as quick as a efi motor will. We were playing with mine when we had it running and it spun up as quick and my efi motor does in the camaro.

And for a drag set up, I think it's a great way to go, back to the basics!!

+1 for tuning on a laptop. Much easier and way more accurate. Harder for initial install but IMO much better unless your required to run a carb for some special class. I like driving when it's hot,cold,humid,dry,etc...... Before the days of the ls motor and its computer and ease of tuning I would have told you different though.

I talked with Geoff at thunder today and pretty much told me that with to run the carb I will need a cam built for the short runner intake. If I can find a computer and harness for a good price for a cable throttle body, I will more then likely try that first.
