I am pulling the 305 out of my 84 z28. I am going to be putting in a 350 with a 4 barrel, I don't want to deal with cmputers. I am looking at an edelbrock package of a cam, heads, and intake. Would you suggest this? I am looking to get around 350 horse out of my engine. What else will I need to achieve these number?

 

exhaust

 

yeah, i am going to put a full dual 2.5-3 inch exhaust on it with probably a couple flowmasters?

Also, what type of body mods should I do to support the torque and what tranny should i look at, it's got an auto and I would be willing to a conversion if i could get a decent priced 5 speed.

 

First, welcome aboard TGO.

The Edelbrock package is a little overpriced and pretty underpowered. The cam is the main culprit, the heads and intake okay, depending upon which package you're talking about.

350 gross flywheel horsepower is pretty easy to obtain with 3rd gen 350 heads. Or, even 305 heads such as your '84 had, if ported and 1.94" intake valves are installed. Mine hasn't be on a dyno, but dragstrip data indicates it's putting out at least 350 HP, and I'm not trying that hard. Gets 20+ mpg to boot.

3rd gen 5-speeds aren't very good. Stick with the automatic, or research the T56 6-speed.

 

Thanks. One of my goals is to also be able to compete in a drag race with my dad against his 2005 mustang saleen S281. It's got a top of the line road suspension and tires so i will need all the extra power I can get. His puts down about 320 and 340 lbs of torque. I think well built 350 with arounf 350+ hp and 375-380 lbs of torque should be plenty along with a nice rear end and tranny. I am looking at putting in 3.73's in the back and 10 inch tires(if they fit) in the back and 8 inch tires in the front. What other frame/suspension mods will be needed to accomodate this power?

 

Subframe connectors. Poly suspension bushings are a good idea, but may not be necessary.

After that, you're looking at boxed or tubular suspension links, such as the lower control arms, torque arm, track bar, etc. Relocating brackets for the LCAs are also a popular suspension change.

 

That sounds like alot of work and I don't know what half that stuff is. I am 19 and have had the car for a year, and needless to say I am tired of getting smoked by neon's with 5 speed. It's sad.

 

The subframe connectors are the big one. Do you have access to a welder, or know someone who can weld for you? The best ones are welded in, but you can get bolt-in as well. My preference is the ones offered by Spohn, but others will be better than nothing. Check the sponsor buttons for Spohn, click on the Parts Catalog link, then 1982-1992 GM F-body, and Chassis, they're currently $195. May sound expensive, but you're talking about a lot more than that for the engine work.

My standard formula is to expect to spend at least as much handling the power as you do making the power.

 

Ok, yeah my dad has a wire feed welder he just bought as well as an old one using the rods. He worked in maintenance for wuite a while, so yeah, he is decent.

Anybody have ideas for a power package from idle so that i can use it as a daily driver as well as having the ability to show up those tuners.

 

Well, let me take another shot at it for you.

Your heads, machined to accept 1.94" intake valves. Ported (Google Standard Abrasives, check out their do-it-yourself porting guide). Either pin the rocker studs or have them replaced with screw-in studs. New valve springs like Comp 981's. Have them put together by a competent shop that can check/repair/replace the guides, install positive-type stem seals, and get the valve seats and spring height right.

Cam - Comp XE274 & lifters. P/N CCA-CL12-246-3 from summitracing.com. $175.99.

Intake - Edelbrock RPM.

Carb - 650 mechanical secondary Holley or Demon. You'll also need a vacuum/mechanical advance distributor.

Exhaust - you already said you're doing it, you didn't mention headers, I hope you assumed you need them.

Transmission - fresh rebuild with Transgo shift kit, Corvette servo, upgrade pressure relief valve, 3000 stall converter.

That combo will produce at least 350 HP, will have decent street manners, and will out-run most of what is on the road.

 

thats funny. i used to have a 2002 es neon with a 5 spd (stock daily driver). i still had the 305 in my bird with ign upgrades and headers/duel exaust. the neon would go 10 flat in the eighth and the bird would be 10.4. pretty sad.

i would go 750cfm on the holley carb. people argue about mathematicaly not needing it but i have personal experiance that the 750 is faster than the 650 on a 350 engine(with the same mods as he speaks of). even so you will have room for further mods with the bigger carb anyway.

 

yeah, stpid ****ing 2000 pound cars. lol. Hopefully when I'm done, even those srt-4's will be beatable, or at least keep up with. heh.
