Thread: any suggestions???

Tweet

i'm building a sbc 350 and have a couple of questions. i want at least 400 horses out of this project, so first off are the heads, i have an option for (casting number: 10110810) Gen 1. 65cc chamber heads, or (casting number 14102187) 1.84"/1.5" valve. which would be the best to use?? next is intake, i have a edelbrock performer 2101, but i dont think it will bolt up, even if it would, would it be a good choice to use it?? and final is cam, i have an xe 286h comp cam. which setup would be best for this build, with spending the least amount of money?? and suggestions, be my guest!! thanks, crazy

Look around here or online for SBC build formulas, they are out there. You will need at leat 1.94" intake heads that are pocket ported. You will need a compression ratio 10:1 minimum. You will need a fairly aggressive street performance cam, preferably hydraulic roller. You will also need a very good intake, single plane Victor Junior for example with a 650 cfm carb. Headers and low restriction mufflers.

Kitz has the correct answer for you. Check out these 108 combinations. They are all built for the street with pump gas friendly static compression ratios. Build for the highest torque at the lowest rpm for a good street motor. Click in the orange area at the bottom of the page for the next group of combinations......

The 10110810 is probably a swirl port truck head and is not the head you want to start with if you intend to make any power over 4,500 rpm's. Same with the 14102187, 305 heads.

If budget is a problem, search the boneyards for a '96-'98 truck with Vortec 350 motor. These will have the L31 Vortec heads that will make pretty good power. Use a Performer Vortec manifold with them. They use rail type rocker arms, so get the rockers with the heads. Look for a sawtooth design on the end of the head and the casting number 12558062 under the valve cover.

Tech, your web link is always a good reference...I need to bookmark it so I can find it.

One major mistake that a builder will make is to assume "it's just as good" because they have the part already in hand OR can get it on the cheap. THIS IS NOT TRUE. Ever. Never. If the engine config in Tech's web link says "using a Crane XX cam" then a "ElCrapo YY" cam is NOT going to to the same horsepower.

It is frustrating to see people waste money when they are on a budget because they buy junk. Junk always is easier to find and probably cheaper to buy. But, especially if you are on a budget, you should be buying quality....if the el cheapo oil pump fails, you saved $30 but lost $hundreds when the engine fails.

The best engine advice I ever got was "figure out what parts you need and then shop for the best price on those parts rather than shop for price and use the cheap parts you found"

Thanks for the link Richard!
