some stock v8 third gens can get embarrassed quite quickly by even a newer grand am, i done up my 350 but still i hate racing those souped imports cause i have to really beat the engine up to get going off the line quickly, what can a guy do to raise the rpm limit of a V8, those new civic si's redline at about 8000rpm i think it is.

So what can a guy do to a thirdgen with a 350 to make it responsive as some of the high rpm motors, i think mine redlines at 6000rpm but i shift at 4-5500Rpm.

 

You need to spend some money on new heads, camshaft, and a shorter runner intake manifold. The long runners of the TPI intake really hold back the RPMs. If you check out the sticky thread at the top of the TPI forum "Our quest for a high flow TPI" you can see the RPMs that a bigger tube runner intake max out at (4800) compared to a siamesed SLP runner intake (5800). Small block Chevy engines typically have a 4000 rpm range where they are effective. You can build for 1000-5000 rpms, or 2000-6000 rpms, but anything more than 6000 rpms and you get really slow and soggy off idle without a 3000+ stall converter.

 

i have a carb and manual transmission chev 350 bored.30 over, crane cam, smaller chambered heads,edelbrock intake, holley carb, headers, igniton etc.... what can i do to this motor make it more effective in all rpm ranges and all gears

 

Well you can get a different cam, different heads, different intake, different carb, different headers and different ignition. That should change things a bit. If you don't understand what I'm trying to point out, we need more specific info of what you actually have. Just saying that you have a Crane cam doesn't mean anything, no magic part numbers fly up off the screen to tell us which Crane cam you're running.

 

bigger gear and you will get off the line quicker

these motors dont have to rev to 6k to smoke a civic

lcarbs to launch it

sfc to transfer the power to the rear end instead of twisting the body with the torque

you have to beat a 4 banger with torque off the line you have to get them or you might as well set the cruise and turn up the radio

 

Or you can do some research like everyone else is telling you and have your parts work with each other, and you'll see higher rpm's. But as with anything, you'll lose out on the other end, namely your torque.

 

I raced a civic si and smoked him thing is he wasnt as far back as i liked, and i know my 355 puts out cuz i raced a restored stingray and 80 z28, the z28 got embarrassed but the stingray held in there pretty close, my problem is my tranny holds me back my diff, and my want to keep the factory hood clearance is a .

So my motor combo isnt important for this question, but in general what makes a good combo able to launch well and able to start a race in any gear?

 

The new SI runs about 15.0-15.3 in the quarter. Thats about as fast as a stock LB9, T-5, 3.42 rear car. Some specs on your ride would help figure out what you could improve on.

 

Dude you really need to look into that Tru-Trac I was telling you about, you'd really be happy. Also get 3.42's or higher in the rear with that tru-trac? You'll be having a blast bro.

 

I bought my motor from an estate sale the guy who built it had a heart attack so nobody else knows exact specs just what was done to it. It is a chevy 4 bolt main 350 common casting from 69-79 used in trucks vettes etc.. the motor has a crane cam not sure of lift but is mild, edelbrock performer dual plane intake, flat-top pistons,hydraulic lifters, accel distributor, accel cap and rotor aswell with new wires and plugs. and accel hei supercoil. he said it had smaller chambered heads with larger valves I am assuming they are 305ci heads, now im not sure but they said dual timing chain on bearings or something like that???, it has an upgraded oil pump as well my gauge shows around 400 practically maxing it out, and I got flowtech shorty headers aswell tieing into a custom 3" y-pipe running out to behind where the cat used to be as i take my time to decide what i am going to do with the exhaust i like the stock exhaust the way you see the two mufflers at the back. As for the transmission it is the original T5 that has been rebuilt 8 years ago and I just had it rebuilt with new everything and i mean everything to do with standard is new even the bolts every bolt, shaft ,gear, mesh, spring ,adjusting rod ,crossbar ,studs ,fork, clutch kit, you name it. factory 10 bolt differential aswell.


Now i know where it can improve kinda the car already goes like a rap#d ape and it still has a lousy Q-jet on it thats choke is broken and no vaccuum lines are connected really, I ordered a new holley 625cfm dp elec choke and mech secondaries, so ill get that on wednesday. the car could use vortec heads or something of that nature and a wild cam, the intake is a big issue as i want to keep factrory ram air hood, i like the idea of having more air in the carb, but we will see, i know it should get a better tranny and diff but i think i am just going to get gears for my diff to make it posi, my quest to go fast is better spent on my other motor combo im piecing together a 454 with a 496 stroker kit from summit with lotsa goodies and a blower. for my 87 cutlass im a little more willing to hack up a bit. so i dont wanna put too much money in a 350 that i kinda hate dont care much for 350's but The Price Was Right lol.

 

tell me more about this tru-trac would it be just the same to get one of the gear kits and put it in?

 

get a 3.42 out of an ls1 car

lcarbs are lower control arm relocation brackets get them for good launches and a set of stickies

I like goodrich but to each thier own

BEFORE YOU DO ANY OF THIS GET SOME

SUBFRAME CONNECTORS

 

I wonder if it is possible to be able to absolutely pin it in first gear and to add something to plant all of that power, i know it is possible to plant power of course but im talking about full throttle take off using a little clutch would it be possible to harness that into a take off?

 

Your problem is your combination. You can dance around that with gears and stall converters all you want, but with your combination made of voodoo mystery parts, I seriously doubt your motor is making any real power. I'd be surprised if it put more than 250 to the wheels.



For those who think this is a little out of hte blue, read this thread:

https://www.thirdgen.org/forums/tech...st-do-you.html



It seems he's all about replacing the carburetor, when the real money makers are heads/cam/exhaust and he's got crap headers, a mystery cam, and I still dont think he knows what heads he has other than they cost him money. So his combination is a total mystery.

 

it is a mystery thats for sure but like i said it goes good now and money for a cam and heads etc,,,, would be better spent on a better motor, so if i can find a way to plant its power it already has ill be happy with it, my quest to go fast will be in my cutlass just cause its easier and cheaper to go with an auto tranny, any more horse in my trans am would require atleast 3500$ for the tranny and another 2200$ for the diff, and another 2000$ suspension so i figure ill just make what i have work i dont wanna end up with a 20K third gen.

 

Then I would do sfc's, gears, then LCARBs, maybe tubular lower control arms too.
