summit cams?

[360demonRT]

so... your suggestion is to run a small cam with a HUGE inake and carb? on heads that woulnt flow past 57-5800 stock? the cam matches the heads... but damn lol, the carb and intake belong on a high winder for sure! i already have valve springs, and woulnt have to machine the heads. thanks for the advice, but i'm gonna stay with a dual plane intake and a slightly tamer carb, and probably the summit cam aswell.

thanks for the info kris. hope i'll have enough compression and gear to make up for your 50 cubes

cam

this is my 383 with that runs [email protected] and a 60 ft @1.64 all that with a comp 268...

i don't know what your goals are? but this is mine

put yours together and come to gulfport on any wedseday night and let lets see 😀 ...jesse

 

[360demonRT]

yea... on a 383 you may need a huge intake and carb... i'd almost wager that with a 3500 stall and a <6k shift point the slightly smaller carb and dual plane would out do the big single and demon carb on a 350 (what i am building). could be wrong, it's happened before. out of curiousity why are you running a little cam in the 383? looks like a cam swap would net easy 11's... and PLEASE dont tell me your going for the sleeper effect with that big assed hood scoop lol. and as far as coming down, if i could find a way to hide enough nitrous to eauthinize a small vilage of pygmies, and afford it to start off with i'd be there lol

cam

thats a great return 😀 no kidding about the set up you see...the .60-350 was running 12.90s on the motor and 12.22 on a 100 shot of n2o...

the reason for the small cam is the cylinder heads...may i suggest checking comp cams online with your combo..you might be suprised at the cam they recommend

i haven't used the n2o on the 383 yet... i need to add a dedicated fuel system for it..i've gathered all the parts..just ain't got around to installing it yet...

i researched my combo before i spent my money and was thinking you might be making a mistake... i don't mean to up set you..just bench racing 😀 ohh, i forgot to say my compression is 11.0.....jesse

i put my stuff together on a very tight budget and didn't want to spend on a set up that would'nt work so well...

my goal is to have a bad assed street car that runs in the 11.s on the motor and in the 10.s with the n2o and yeah there's no sleeper with that hood! i have been working on the hook up and to stop pulling the wheels and wasting hp...jesse

Jesse, your cam is the XE262H correct?

That or the XE268H would be a good match. Plus the Xe series cranks up cylinder pressure so it will "act" like a higher compression motor.

Better yet, VooDoo 60102 , great match to Vortec head design.

The VooDoo and XE series were designed by the same guy!

didnt upset me 🙂 car should be running saturday (stock rebuild 95 350) just to get it moving. then gonna be changing stuff around piece at a time till i get it where i want it. it'll be a while tho, gotta save for my wedding lol

IMO, a larger cam is not always better. It really depends on what your aiming for. I went with the summit's .442, .460 cam and it has done wonders for me with my 2.02 heads, edelbrock 600cfm carb, and performer intake. Right now it dips into the high to mid 13's and gets 15-18mpg. Great response off the line with my 373 yukon gears.

Now I know there's guys out there saying that mines a baby cam and the 350 can handle a much larger cam. But its not always about who's got the bigger stuff. A cam is simply one component of the overall picture. Sure I can run a 500+ lift cam in my 350, but is it really necessary and are the other components of your engine able to deal with that? The idea with my motor is a decent cam with larger than stock heads. This provides for better fuel distribution within the piston chamber and better combustion providing you with a motor that won't bog out or just go from gas station to gas station. Gives great gas mileage when normally 350's are known for horrible gas mileage and can beat most of the mustangs on the street.

gas mileasge :? whats that? lol. i have a neon to DD, so i dont care about gas mileage... i want a pretty much a full out drag car, just BARELY tame enough for the street. to clarify a little. i want it to go as fast as possible with parts i can afford, sacrificing what i have to (hell... i dont have heat/air/ac/wipers/ps.... or really any other creature comforts). right now the goal is some 12's. may change depending on what happens down the line

 

[patmckinneyracing]

Same here. My goal was finding the most amount of horsepower with decent gas mileage since I drive mine everyday. Nice to be able to drive it everywhere and not look at the gas tank every 5 miles. :lol:

I second the .442/.465 grind. You need to build the engine to make good torque in the low to midrange area. Even at the dragstrip the engine spends very little time in the 5000-6000 range. Build it for torque, this is what accelerates the car. If you want lope keep the duration short (215-220)and tighten up the lobe separtion to 106-108.

This is the one I went with and I'm very pleased. I used to buy from Chet years ago.
