343 intake manifold

----------

Does anybody know if the Intake manifold that Edelbrock sells will work on a
68 - 343.  Their site says it works with yrs 70 and up but I wonder what the
difference is in the 68 and 70 engines.

Here's the link to their site

<http://www.edelbrock.com/automotive_new/mc/manifolds/amc_perf.shtml>http://www.edelbrock.com/automotive_new/mc/manifolds/amc_perf.shtml

Also is there any other good manuf of intakes that would work....thanks
again for you help...

Edelbrock use the code phrase non-EGR to mean early manifold for 
66-69.EGR is for 70 and up AMC V-8s. The deck height changes about 
.045 of inch, not much, between the early and late manifold but the 
center two bolt holes are relocated about 1\2 inch. No a big deal. 
You basically have 2 choices the newer air-gap and the older 
Performer. The performer is stated to increase horsepower from idle 
to 5500 rpm , the Air-Gap 1500 to 6500. Non -EGR Performer part 
number is #2131, later EGR is # 3731; Air-Gap is non EGR is 7530, EGR 
is 7531, add another 1 for polished if you want to spend the money. 
I'd go with the newer Air-gap as it will give a little power on 5500 
to 6500 rpm range. LRDaum mramc@xxxxxxxxxxx
