welcome to FBBO
not really know your exact combo
but by what you said you have & a few assumptions
wild *** guesses on my part
performance 101;
the fact you have power brakes &
a restrictive factory intake not made for higher end performance &
restrictive exhaust manifolds & highway gears &
probably a stock torque converter, stock rocker arms, springs & retainers etc.
{
none of which are really suited for too much camshaft probably stock carb, stock ignition,
stock style air cleaner, stock drivetrain, all of which are not suited for performance use}
can make an issue in proper selection
on a real performance camshaft selections
bumpity bump, bucket tee, bucket tee, sounding cam
they tend to not make much vacuum at idle
or low cruising RPM, your exhaust will hinder it too...
you could do some other things,
it's pretty involved to help or to solve it...
a little on the subject;
without milling the tops of the valve guides
{
not knowing what work you had done already}
about max of 0.500"-0.510" gross valve lift is safe,
also much more than that can have
"piston to valve clearance issues"
depending on camshaft timing
much more than that you can get interference issues
a little more info;
duration is where you get a lot of the
bucket tee, bucket tee, bucket tee, sound
with stock components like intake & exhaust manifolds
it will be a dog, not up-to it's potential,
but have a good thump sound
a 284*-292* degree (
advertised duration & not at 0.050")
& with appr.
a gross valve-lift of 0.484"-0.509" gross valve lift
the gross valve lift
is camshaft lift x rocker arm ratio = Gross valve lift
camshaft will have a good, sounding aggressive
bucket tee, bucket tee, bucket tee, lope to it...
A better free flowing exhaust & headers will help sound
a shitload too...
talk to a camshaft expert 1st
too lengthy to get into here
this is just the
welcome wagon forum
it's not intended for Q&A tech discussions,
it's more for intros & getting to know each other
sharing a couple photos of your car etc.
but that's a whole differ section of the forum
I'd suggest you post something in the
general discussion forum
or a different related appropriate forum section here...
good luck with your decision...
