Q: I have a third-gen Chevy Camaro RS.
I’d like to build a 350 for it that puts 400 horses on the ground, and I’d like for it to be an “all-motor” Camaro, without nitrous.
My plan includes some high-compression pistons and a big cam. I was also thinking about putting 305 heads on the 350 to increase the compression ratio. I’ve been told that the 305 heads flow better than the 350 heads.
What do you think?
I was also considering Hooker long-tube headers and a 3-inch Flowmaster exhaust, and I’ll probably need to change my transmission, too. Can you point me in the right direction toward 400 hp?
A: You can get 400 hp out of a small block 350 and keep it streetable.
First, stay away from the 305 heads. They actually don’t flow very well, and since they’re cast iron, you can only go up to 9.5:1 compression.
We’d recommend a set of Trick Flow 23-degree 195 heads and a piston that will run on pump gas and withstand 10:1 compression, like these Keith Black hypereutectic pistons. Combine this with an Edelbrock Air Gap intake manifold, a Holley 650 cfm carb, and a cam with around 235 degrees of duration at .050 inches and .500 inches of lift (like this COMP Cams camshaft), and you should be at 400 hp.
I used the hot hot hot cam build I love it
Jeff Smith hows the Stein build coming along?
That build is really close to what I have in my 89 camaro. Except for the fact its a 388. ( .60 over bore)
You meant .060 right .60 is over 1/2 inch?
The Holley 650 cfm twin feed would be a good choice if you plan on sticking with a carburetor. It’s a 4150, choke horn # 4777. Mechanical secondaries, double pumper, and mechanical choke. I ran one of these units on a SB Ford .030 over, a set of AFR 165cc heads an Air Gap intake and a .512 280 duration cam. The thing screamed. Sounds like you’ll have plenty of air flow, and enough cam to Use that carb. If your. Still running the stock rear end, you may want to consider upgrading. Have fun.
Is there anything I can do with a six cylinder 2014 camaro it’s got 305 horsepower something like that ! Something bolt on ? Maybe a chip ? How much horsepower do u git from headers ?
Hey Steve–absolutely. There are plenty of bolt-on upgrades out there for your 2014 Camaro 3.6L. Start with the basics: Intake and Exhaust. You can also tweak some engine parameters with a good tuner/programmer.
And don’t forget about upgrades to the suspension, brakes, and other areas too. The Camaro has tons of aftermarket support, so you’ve got a pretty good canvas to start with, Good Luck!
But be mindful of local codes, in certain areas changing/modifying engine (and related) components can violate local regulations.
Or with the new Edelbrock AVS2 carby you could go with a bigger cam and heads to get even more power. Its got Annular flow primary boosters in it. Sorry OAC. Staff.
I have a 1984 Chevy c20 p.u with a 1988 350 target crate engine,four bolt mains.quadra jet that is spot on perfect.. what can I do to up my power?
I got a 81 k10 with a 350. I got a K&N top/sides air filter, Edelbrock avs2 650cfm carb with 1″ four hole spacer, edelbrock performer rpm dual plane aluminum intake, idle to 5500rpm slight lope comp cam, corvette crate engine heads, hooker long tube headers to two single chamber race mufflers (true dual exhaust), 15 gallon fuel chamber in bed, 4-9psi electric fuel pump, k&n in line fuel filter, fuel pressure regulator set to the edelbrock psi specs. Th350 transmission with a stage 2 b&m shift kit and a huge cobra trans cooler. Lightened pulleys. Dual electric fans. Previous owner put in billet crankshaft and upgraded forged pistons. Itll spin 38×12.50×15 mud tires and chirp second on regular road and throw mud 100ft high. Its a rust bucket but a monster lol
Hello, fellow gear heads. I just wanted to say that it’s nice to see others such as myself doing some decent builds and having fun with it.
I have a question and was hoping someone would and could point me in the right direction…Here it is…
I have a 1997 Ford Expedition, 4.6 liter with a 4R100 automatic transmission. I’m looking for a place I can either buy or have an adapter plate made to mate a Gen 1 SBC TO THE 4R100 tranny.
Any ideas? About 10 years ago I purchased and mounted a SBC 383into a 1979 Porsche 911 Targa. It was sweet to say the least. But, the company went out of business. So, now I’m stuck. Any help would be great. Thanks and be safe!!
I’m going through the inter-webs, reading forums and attending YTTC “YouTube Technical College” (hehehe)..Trying to get a better understanding of motor options with my ’72 C10 truck. It has a stock 350 SBC and I want to either SQUEEZE as much HP out of it as I can or consider saving for a crate motor (which seems pricey). I’m not looking to do any racing, but I want a little fun when getting on the throttle (thinking 350-400hp range if possible). But because I’m on a budget and trying to do things myself with what I have, it makes some sense for me to upgrade my 350. I’ll admit I’m no master mechanic, but I’m no newbie around the shop either (Intermediate level I would say.) What are some good sites/links to walk through a step by step novice style with basic upgrades/bolt-on parts, Cams, heads, etc. (do I have to get the block machined, or is machining part of the cam/head process I’m not too sure on this?) I’ll be doing the work in a home garage. I’ve never installed any heads or cams but I’m willing to learn and have fun with it. Sorry for being the annoying new guy here… haha. Any and all info is appreciated, Thanks!!
