Eddelbrock 350 Questions

[chadvicki]

I have the Eddelbrock 350 with 290hp. I am using the QuadraJet Carb. I have stock exhaust manifolds and two Flowmaster exhuasts.

The truck is a C-20. My gearingis 4.11 I believe or whatever stock was for 1972.

What are somethings I can do to make this truck a little faster? I have a Turbo 350 automatic trans. Maybe a rough estimate on cost for each item if someone else was doing it.

I'm just looking for some more ooomph out of it.


Thanks guys,

Chad

What intake are you running? Edlebrock make a few good intakes that can be purchased second hand between $70-150, add the cost of gaskets and if you do the work yourself it's under 200 easy. Whatever your project is member of this board can talk you through it, save your money on labor and buy more parts.

How do I tell which one that I have? Is there a number somwhere on it?

If you already have a Edlebrock intake on there it should be a 21XX, Like a 2101. Look on the back side upper manifold deck between the carb & Dizzy for rasied numbers. Your tire size and gear ratio play a big part in you top end speed. Do you still have the glove box sheet? It may tell you on there what rear end you have. Other considerations are: age/condition of the wheel bearings and brakes that drag.

When I am on the freeway I am at 3,0000 rpm's going 65mph.

So if I change the intake and carb and put headers on is that going to make any difference in the around town acceleration?

probably won't be that much of a differance. You'll notice a little - but nothing crazy. You really can't just "throw" some parts on a motor and expect it to go faster (ask me how I know been there and done that)

you really need the right combination to "go fast"

the 290 horse should be plenty - stock manifolds flow pretty good as they are the Ram-Horn type. I would stick with them as headers require more "maintenance"

quadrajets are good carbs - maybe it just needs to be tuned

like I said you fighting against the weight of the truck

Nitrous!

Get a C-10 ShortBed!

You want to go faster on the highway? in town? what is slow about it now? can't keep up with traffic?

In all seriousness a C-20 wasn't really designed to go fast.
It is heavy and getting it motivated will take some effort.

the 4:11 gears will get you around town good, and help you off the line with that big heavy truck, but on the highway they will limit you in the "speed" department.
