how many cold cranking amps required

for a 454 with a MILD cam. cam is basicly one step up from stock.

ill recheck all of my connections and plug wires, engine is getting gas and turning over but seems to be turning over slow.

reason i ask about cold cranking amps, this battery is charged and came out of my 2002 silverado 2500 hd 6.0L and was in the truck when i purchased it used. i was told that the battery that was in the truck (now in the camaro) did not have the required cca for the truck. with a bigger motor in the car, wondering if the battery doesnt have the juice required?

What's the CCA rating on the truck battery?

I'd think pretty much any full size battery would do. Unless your BB has significantly thicker oil or higher compression.

Sounds to me like you just need to charge the battery.

Should have 12.6 to 12.7 volts just sitting there.

The more the better, I NEVER go cheap on battery.
800-1000 if I need it or not.

Good luck.

Being in Ca. c.c.a. is kind of a moot statistic.What you need to consider is the pulse cranking amps(5 sec. rating) if it cranks slow.

At one time, when High compressions of 10:1 or higher was the norm, 1 CCA per CI was the formula.
350 CCA was plenty for a 350.
Battery technology has advanced and car electrical demands have kept pace.

Most batteries have 500 CCA or more which is more than p[lenty to spin the starter in San Diego.

You need to 200% make sure the battery is grounded metal to metal to the engine block, not an accessory like the ALT bracket but the block itself, with a pigtail that goes to the body, body and frame, engine and body/frame etc.

your silverado battery is more then likely a 78 series which means it has 800 CCA if you bought the good one. or it could be a 75 series battery, 78 series is a little wider then the 75. the 75 series battery has 750 CCA if you get a nice one.

This should be enough cranking amps for that motor and starter if not get your self a nice 75 or 78 series optima and a nice gear reduced starter, and i will promise you will never have an issue again!

Have you checked the voltage while cranking?
Are you sure your grounds are all correct, especially the path from engine block back to battery?
Do you know that the starter is a good unit?

I am running a 500 cca battery with huge 2 speed electric fan, AC, and EFI in one of my vehicles...yeah it's definitely too small on paper but it has not stranded me yet. Check yer grounds for sure, if you don't have a ground strap from the engine to the body you super duper need one.

starter is brand new and working fine other than slowly cranking.

neg of battery was going to the alternator bracket as i had always been informed was correct. will move to connect directly to the block.

will install neg to body also. i know the body was previously grounded as the gauges were grounded to the body and working fine

engine ground strap to firewall is solidyly connected.

battery terminals will be reconnected and made sure to be solid.

volts on older battery were 12.0 prior to cranking and 11.9 when i gave up. ill pull the new battery and install in the camaro

will prime oil again,
will line up timing mark at 0degrees on the timing mark on the compression stroke/tdc. rotor at #1 plug wire, and fire away.

am i missing anything here?

12.0 sitting idle is close to dead. Fully charged and holding should be 12.6-12.7.

I use an Optima Yellow Top Group 51R (Honda Civic size) battery to start my car. It's rated 500CCA, I have my doubts since I've killed it to <2.0V several times now. But, it rolls the engine (mild 350) no problem.

Bench test the starter just to be sure - new doesn't always mean works correctly.

DBL check for full voltage at starter solenoid (~12v). I'd jsut dbl check all points along ignition system to be certain that they are receiving proper voltage...shouldn't take too long to do that for peace of mind.


AT correct? Is tranny in Park/neutral? If neutral safety is bypassed could be in gear...just extra drag.


So you found a carb then? LMK if you still need one.

If you've cranked the engine at all, DON'T Try and "re-prime" it. All the oil you have pumped up to the passages will drain back to the pan when the Dist is removed and then whem being reinstalled. You don't have a lubrication problem now, but you can create one by doing that.

Reset the timing back to 0-10º BTDC is fine.

90% of the time its poor grounds. You may need to put an ohm meter on the ground terminal and block to check it. It should be zero.

all connections reconnected, new battery used with 12.2 volts to start. ground on the battery was connected to a header bolt on the motor (will this work? dont have any accessible holes that will fit the battery cable on the block. i have a few that will work but will have to grab a bigger end for the neg battery cable as they are 7/16. motor ground strap connected to firewall and back of block

engine was set dead on 0deg, rotor pointing toward number 1 cylinder AND number 1 wire. motor is getting fuel. used starter fluid this time and NO DICE!

THERE IS NO F'ING SPARK. put a bolt in the number one wire and placed it right next to the block, no spark jumping. the rotor does turn when the engine is bumped and the cap is off.

BRAND NEW CAP AND COIL, accel hei cap and coil. 12 volts to the battery terminal on the coil that is hot, tac terminal to the gauges. gauge registering 0 rpm before cranking and 0 while cranking.

no trans installed at this point flowjoe, simply engine and wiring to start

hhot71, i will check with the neighbor and see if he has an ohm meter. and thanks for the advice on the priming. saves me a lot of time

wondering if the header bolt may not work as it is insulated by a metal gasket to the block? should i remove paint where the ground strap on the motor contacts the firewall? i am using a strap with "claws" at the end to penetrate the paint.

sounds like we definitely have a ground issue for both of these things to not be working now. I would not ground to the header, ground somewhere down low on the front of the block and use a star washer under the cable. I was just going crazy w/ weak cranking problems on a new built the other day and it turns out (super embarrassing revelation) that I had initially grounded the cable to the big aluminum serpentine bracket using a black oxide bolt and....black oxide when I tested it w/ the ohm meter, does not pass current. Woops.
