2. Do a cam swap, summit sells a 422/444 lift cam that would work well. It is $70.00 for the cam and lifters.
3. Make sure that your headers are 1 5/8" tubing. Too big is not good on a 305.
4. A good distributor or a rebuild of the stock one with a 50,000 volt coil.(Accel Supercoil is a good choice, their Brute Thunder is a little more voltage, but it fits under the cap like a stock one)
5. A nice flexfan would help too.

Now with the Cam and Lifters, How hard is it to install?
I have a Cam in their now, that came with the truck, but it is a High End Cam. Power is horrible down low.
I like to do all the work myself and Im 18, I know alot about Trucks, especially GM. I built my first ATV when I was 12.

You can swap the cam as mention prior for an RV type cam, which takes advantage of your hp at lower rpms.
You can swap your rear end with a lower (higher number) gear and get a pleasant jump from down low.

Higher gears would never have to come out because you would love the nice jump off the line they give.They will burn a lot more gas the higher you go.

I wouldn't go over 3.42's if you plan to drive it on the street.

A little girl on a Bicycle can take me out off the line.
I heard that a 3:73 would be good, But I shouldnt be reving to High since I Manual Shift anyway, I have a Custom Built 350 Tranny that allows me to shift while still having an Auto.
When I bought my Truck, Almost everthing was in Stage one of Building to race, I have a Modified Tranny and Shift kit, A huge 12 bolt rear.
Only thing is the engine, The guy I bought it from had a 383 stroker engine he was planning on putting in it, But decided to sell and put it in a Nova.
I was looking on eBAY for an engine, and I came across a couple of Rebuilt 400 SBC's for under 2 G's.
I may do that one day, Its just what to do now?.
I Deffinitly need to open my rear to put Posi in, So while I am in there, I will Get Ring and Pinion as well, Its just deciding what gears to get for what I want.
I basically want this truck to Go fast, and Quick off the line.
I am a Major Import Hater, so any chance I get to beat them I take, and so far the only thing I can hold up against is the Basic Civics.
I dont race all the time, But when I get on it to speed up, Power is bad.
I just want to fill the gap, Yah know?

I have 3.73's in one of my trucks and it'll do 70 @ about 3K RPM but I hardly drive on the highway so they are perfect for my truck.

But still, unless you have an overdrive /or really large wheels like 18", going 60mph on the interstate will cause you to tach quite high....many rpms = lots of gas.
It wont be as bad as 4.10, but you get the idea. YOu have some options.

Use a calculator like this one to get an idea. If you have a 3 speed automatic your drive range ratio is 1:1

And don't forget to re calibrate your speedo when ratios are changed.

Nope, not many of those on pickup trucks. I see a lot on sedans and foreign jobbies. I am not saying there are none. Most pickup trucks around here are used for practical purposes, and not for show---I'd like to see a 4x4 with those low profile tires on the outer banks of N.C. on the beach, or out in the fields hunting--that would be a sight.
I have seen those things on newer SUV's and such--they look horrible--perhaps I am old-fashioned.

I dont know what gears Im running now but they suck.
I am gonna be traveling about 30 mins to work once I get to my new house, So I will be crusin at like 65 or so.
So you think I shouldnt get 3:73's with that drive, I already get crappy MPG cause of my carb runnin rich.

I built a mild flat top 305 with Edelbrock Performer cam ( same exact cam as the Summit cam mentioned earlier, Performer intake 570 CFM Holley carb, small tube headers. pulled strong to over 5500 RPMs. ran mid 14s in 1/4.....far from fast by any means, but it was fun.
I also built a little healther 305 for my 86 ElCamino, 10:1 L-98 aluminum Vette heads, performer intake, 570 Holley. 13.30s with 3.08 gears : )
Post by: Foxracing500r on November 01, 2006, 08:58:00 am
So after that I will look into Edelbrocks Cam and Lifter combo for the Performer RPM intake.
I noticed too, After being up here at around 1600 ft. My truck runs like a champ, The Low end tourqe is good and its faster,
So I may hold off on gears for a while, and get the Front Fiberglass Fenders and Hood, and Modify that cam.
I thank you all alot for your help, as you have answered my question in so many helpfull suggestions.
