hey guys.. installing my H/C set was done yesterday, this is going to be my very first experience of H/C set ( driving or riding as a passenger)... i installed patriot cylinder heads 62cc i think so not sure. the main issue is that when i'm in the car n its on park everything is great and the sound is beautiful but when put it on Drive the whole car is shaking(a bit aggressive) including me(RPM goes down/rough idle). Since its my very first time, it felt a bit inconvenient. i know part of it is because of the cam, cam specs r (COMP cam 224/230 .581, .595 112)... cant remember exactly wat was the exhaust lift but 100% sure .59ish.. and for safety i got double chain SLP timing set but it requires a diff oil cover and pump, because i was in a hurry i left the stock timing set on n swaped the chain with vette's stock chain(mine was looser)...
My questions are:

-does the stock timing set have ANYTHING to do with the whole car shaking on D? if no then how much would it last? if yes then how serious is it?

-or is it caused only by the cam? i know its a big camp, my car is supposed to be daily use car, so is it a daily use camp? do u think its too much/too big?

other info:
car: 2006 chevy lumina s(car for the middle east only) 5.7 ls1, A4
other mods: flowmaster exhaust, weiand intake maniflod, k&n air intake, spark plugs, ignition wires, headers, eibach springs(lowered a little over an inch).... any other info or details needed let me know.... any kind of help is very appreciated... thanks in advance....

any ideas??!!

Your car shakes in D because it's a medium size cam without a tune to trim the spark and fuel. A good tune will eliminate most of your problems.

the car is tuned to fit the cam's specs...

Are you still running the factory stall?

Maybe the motor mounts aren't so great or the tune is still a bit off. My cam is way bigger and does'nt shake like your describing. Not still like stock but does'nt shake violently. Maybe it's just your perception of how rough is rough. Good luck!

Like someone else asked, what about the converter? Is it still factory? If so that's a problem. It isn't that big of a cam it should be fine with a good tune.

you need a tune and a converter my friend...I say get a mail order for that combo since it isnt ***** out...

When you put it in D the idle speed drops down obviously, which will make it lope more. I'd say since your use to the stock setup, this may seem a bit more agressive than you were expecting. If you have it dialed in with a dyno tune, and have all the correct components, then you should be fine.

yeah i'm still using the stock converter.... thanx guys now i have a bigger idea of wats goin on...

nalzaki

i've been doin little research on the forum with similar problems. n came to few conclusions n i need ur suggestions to go with which one:

- drill a whole in the TB... well mine is electronic TB would it still work?
- new converter
- retune... even though the tunin i got is supposed to fit with the head/cam specs
- manually adjust the idle??!! (electronic TB, would still work?)
- PCM learning, drive it for few miles n maybe it will adjust

one of these should work, what do u guys think???!!!

Asmodeus

I'd start with the convertor first. And another bump for you
