Hello all I'm new but i would like to say hi, before i ask for a little info. hello.
my problem is with dss racing. i bought a long block on layaway in February of this year and finally paid it off. i just installed the motor and i have 2 huge problems with the motor. first is a ping that i cant get rid of after trying a few things, like a 255 fuel pump, and the fuel pressure is at 38 psi did not fix bad ping. next I'm gonna try a colder plug. the other is a huge vibration in the motor.
spec on the motor is a dss 331 long block pro block with forged internals and i beam rods with Afr 185 heads and 64 cc chambers.
added a comp cam 266 Xe with 544 lift and 555 respectfully 1.6 rockers.
added msd distributor. performer rpm 2 intake 30 lb injector 255 liter per hour fuel pump huge power pipe for accufab 75 mm race throttle body and 80 mm mass air from the new pro m, and a edelbrock water pump with 180 degree thermostat. i have a 28 oz balance, and 28 oz flywheel with a stage 3 clutch. new t5 world class trans . I'm trying to fix the pining, and balance of the motor. i had to have the rockers all readjusted today because dss did not do it or say i had to adjust them before i installed it. it cost me 200 dollars more. plus the bigger fuel pump cost another 200 but this did not solve the ping problem. compression is close to 10.4 to 1 thanks . also what about the balancer i am sending for a new balancer just in case i was sent the wrong part . please help with my dilemma thanks guys. any other suggestions to fix either problem. I forgot to say i have 10 degree of timing and 93 octane fuel.
Did you have the car tuned when the engine was installed? Also have you checked the timing advance to see if it needs to be pulled back some?

yes i tried higher octane . also I'm sure its a 28 oz balanced motor. thank you for the help. i will be trying colder plugs, and after that the stock distributor for the ping. a double dose of octane and a bump of the fuel pressure to 40 or 42 lb
almost certain i have the pinging under control, i did not go with a colder plug yet.
what was done is this, the timing was set to 28 degrees with the spout connector off.
under load the motor will go right to 28 degrees and the computer is locked out of the scenario. the spout connector resides in my glove box. the engine builder said this should lower cylinder temp and with a few more tweaks unknown to me at this point, we may even be able to use 89 octain fuel. pretty cool, but yet to be seen. please take a look if you have questions. the only adverse effect to taking the CPU out of the scenario is harder to start in hot temperatures because we are using a higher time curve than if the CPU was controlling it. in this case i have a high torque starter, and it cranks right over.
hey man, im glad you have it almost figured out! I actually have aa question for you. See, Im just about to pay off my 331 pro bullit from dss.... I have everything to go on it from my old set-up. A performer rpm II upper and lower...1.90/1.60 edelbrock performer alum heads, anderson n41 cam, 24lb inj., 75mm mass and tb/egr, afco alum rad with elect. fan, msd billit dist. digital 6 with coil, 1.6 scorpion rockers, new lifters/rods/and gear drive, Your article has me worried about the install...also a 190lph in tank...too small? should i get the 255? What other recommendations do ya have for me.. appreciate anything you got. The car is getting prepped for paint now, install to follow! I like your ride, mine is 86 hatch with all interior upgraded and aa bunch of goodies like yours. Hit me up with an email at......onefastang50@aol.com Thanks man
Something is wrong and you will void your warranty if anything breaks.

DSS? Who?
ANYONE that tells you to run a daily driver with the spout out is an idiot! That person is just not capable of tuning your car properly and running spout out is a bandaid.
DSS sells motors. They don't tell you to adjust the rockers....ANY competent installer will do that 100% of the time before first firing.
You have issues, but they are not with your new long block.
I may be wrong but aren't 331s suppose to be 50oz and the 347 is 28oz balance? That might be why you have vibration issues.
I just bought a DSS 331 and it came with a 28 oz crank......

Did anyone look at the date of the op? This has been dead for 2 1/2 years!
True but it got me worried because I just bought the same short block and my vibrates like crazy too....everything on the motor is brand new. My 331 is a 28 oz balance. My vibration is still there and driving me crazy.

Haha just when I think I want a 331 from DSS I run across a thread like this...So whats the deal with the vibrations?
Seems like after selling as many engines as DSS they would know what balancer to use! I liked the idea of the level 20.
Shouldn't the assembly get balanced with the balancer and flywheel that will be used. I didn't see that option on the DSS site but had planned on asking if they could do it.
Who sells good 302 based engines besides DSS?
Im about ready for a short or long block 331.

DSS quality is pretty much in the toilet now, sorry to say it! They did GREAT work years ago!
But I heard the new staff is CRAP!
I would not buy a motor from them!
