GT40P's and manifolds

Blaster · 02-23-2001, 04:15 PM

I've run into a dillema. I want to put new heads and intake onto my 91GT but I'm not sure what will give me the best bang for the buck. The GT40P heads are very reasonably priced but i'm not sure if my unequal 1 5/8" MAC hedders will fit and if the heads are worth it compared to say the Edelbrock performers etc. Also I can get a good deal on the explorer type manifold but will it be as good as the Cobra intake I originally planned to purchase?? Help!!

The heads are ok, could give upwards of 35 hp w/ an intake.
You will have to buy p-specific headers because of the plug angle/clearance problems.
Although i've heard of people grinding the flanges.
Compared to the edelbrocks.....not even close
The explorer intake(upper) will require some kind of modification/re-route.
I forget what...not a biggie but my buddy used one.

I have been doing some research on these heads for my future purchase. They are not even close to the edelbrock heads,but they are half the price too. Also you will need (p)headers. The only problem I have found with this is there are only two companys the make them and they are both shorty's.The explorer manifold is good for the money. You will have to move the ACT sensor to the inlet tube(no big deal). I wish I would have know about it before I purchase my cobra. If you buy a combo(heads and intake)you can should be able to find a good deal.
