Thread: Up grade ideas

  1. #1

    Question Up grade ideas

    Hello there people,
    I want to do a lot of up grades to my 1986 Chevy suburban, but I don't know really what kind of intake, carb, air fliter, and any other really horsepower ungrades.
    ideas would be nice thanks you

    does youre ride have a 4bbl carb?does it behave nice,if so id leave it,h.e.i distributers are powerful,hate to say it cause it costs some coin,get a set of good heads,i think thats the best bang for the buck,intake and carb you will only notice at higher rpm,better to have the power off idle in my book,sorry im getting old

    i forgot to ask ,small block or big block?must be auto tranny?dual exhaust?

    Ya it's a 4bbl and the a bad ass... It's has less then 50 thousand mile on the new motor and heavy duty tranny... And ya its a auto but its a straight axle O has the back end welded for towing to.
    350 and straight exhaust

    What kind of heads?
    And do they make a cold air intake for my year?

    strait exhaust?duals or single?think of this,the same year vette put out a lot more h.p.,mostly heads,a bit better exhaust manifold,youre one downfall is comp.ratio,not the worst thing,does make a diff. thou,check junk yards for wrecked vette motor,you never know,or hit a couple of sites,p.a.w.,summit,edelbrock,and tons more,just remember,show dont make it go,its whats inside that makes the real diff.
