Tarantula intake

[Tx79chevy]

Maybe one of the old school guys can help me out on this. What do yall think about an edelbrock tarantula intake? I have a 350 that it would be going on.

All the newer stuff will kill that thing. If I remember correctly, they were high rpm and peaky. It depends on what you want. It might look cool but I would not want it on my truck or car, not even to race.

More than likely youre gonna feel the loss on the low end more than the gain up top. You could counteract it with a stall though.

I dont have any advice to offer on the intake, but im right down 31 from ya, over in chandler. If you ever need a hand or squarebody parts just contact me!

Just thought about it, Ive got a couple weiand intakes if the one you have wont work.

Previous mentions of the manifold are correct. You wll loose low end but mid range to high rpm will set you back in your seat. More of a real high performance manifold for racing only (circle track or 1/4 mile). Not what you would want for a daily driver. I have a similar one on my cuda but I quit driving it on the street 25+ years ago. It got about 6 mpg and the stall speed made the tranny run hot on the street. But when you nail it in that car it's "Whats my lane??? Ok I'll take both

Only if there's enough motor.....

Tx79chevy,

What are the specs for the motor that you're considering the 'tarantula' intake?

[Tx79chevy]

Its a 350 bored 40 over, 292 cam 480 lift

What compression? What are the head specs?

Are you considering the intake in question for your street truck? If so, there's no way a single plane intake will out perform a good dual plane intake on the street. Trucks are porky & need all the low end grunt they can achieve to get things moving (which is what a dual plane intake is made for).

This is the first engine I have ever had a hand in rebuilding, so I am just now learning about all of this. My father in law is helping me with everything. He said it should be 9.5 to 1 compression and I believe the heads are 441 heads, hope that sounds right. It has comp roller rockers, not sure what the exact specs are though. It is going in my street truck. Most other things I have read recommended the edelbrock rpm air gap intake.

I ran one back in the late 70s on a 283, big cam and 4-speed ran good. Thought I had a picture of the motor.

The RPM would be my suggestion as well if it's a street vehicle. A track vehicle would benefit from the single plane but even then there are better/updated choices vs the old school tarantula intakes.

my weiand high rise single plane runs great on the street!!

who needs low end torque on a v8??? they have planty enough all the time

if anything a torker single plane is still a great powermaking intake thats good on the street.

just dont get the torker II

[john_p]

in their day they were top of the line.. i am sure the new stuff has a lot better hp curve.. i added one to a sbc in a 57 chevy and dropped .2 seconds on my et.. that was over a stock intake..

[Tx79chevy]

Also, would a 750 carb be too big for my engine? If so, would a 650 be better?

[rayfinseats]

You gas milage is going to suck. If it's a 2wd with deep gears it will be loud but probably not fast. If it's an automatic it's going to be a real DOG unless you run a high stall torque converter. I hope you have at least 3:73 gears. Good luck and keep me posted. 750 too big unless drag racing, go with 650.

Your RPM range will be in the 3000-6000 range. My truck usually runs around 2000-2500.

[Tx79chevy]

I am getting a high stall torque converter and putting 3.73 gears in it. Yes it is an automatic.

750 is too much for a sbc imo. 500 or 650 would be better.

[SCOTI]

a 750 is one of the most versatile carbs made. Set-up right, it will do fine on a 350 sbc. Fatten it up & do the right tweaks, it will be fine on a large 400+ ci sbc. If the rest of the combo supports it, the 750 will work.

Only tuning will tell you if the 650 or 750 is 'better' vs the other as every combination is different.

Agreed. The bigger the venturi the lower the vacuum signal. The lower the vacuum signal the harder the carb is to tune at low speeds and partial throttle. Going with a smaller carb might make slightly less top end power (but only on a fairly stout build. Mild, streetable builds won't suffer much if at all) but will be more drivable at lower RPM and on/off throttle transitions.

[Tx79chevy]

Yeah I will only be driving this truck on the street. Might not ever even take it to the track and yes I know it won't get good gas mileage but I only live 3 miles from work so i'm not worried about that.
