Hi
I just bought a 94 yukon and I want to go with some performance
upgrades. I have installed a chip from hypertech ( Works great ) Air
Raid intake Dynomax Free Flow muffler ( Ill be changing that out soon
to a better exhaust headers etc )
   I have a guy who can get me an edelbrock intake manifold with a
holley 670 cfm TBI carb. My question is what could I expect in regard
to HP or tourque gains by going with this set up. Would it be wise to
install that now..I dont plane on going with a new cam or heads as of
yet. headers would be my next choice. Id really  like to buy this set
up but Im not sure if it is applicable at this time. Im a an amature
when it comes to moding stuff but I do want to learn and any advice
would be appreciated.
    One last thing I was reading about 350s with smaller intake ports
on the heads that didnt do well withthese mods.Im wondering if my
heads are of the smaller variety this guy was tallking about. Again
any help is appreciated as I would like to by this thing if it will be
of benifit to me.

Thanks again

sincerely

Mike
