Yes, all tradional Pontiac V8 (287,317,326,347,350,370,389,400,421,428,455) heads will physically bolt to all blocks. The later 265/301 will bolt to older blocks also but the water passages between the head and block are different and there is no available intake manifold. 6X heads came on Pontiac 350-400 from 1975-1979. no 455s were factory equiped with 6X heads. There are two versions of the 6X, one stamped "4" and one stamped "8" the heads stamped 4 have smaller combustion chambers around 94 cc, the one stamped 8 are about 100-101cc. The 6X-8 head would give very low compression (about 7-1) the 6X-4 would be better but is still only about 7.6-1. High valve lifts can cause valve to cylinder wall interference on 350s since the bore is only 3.88".

OK, horse power is tork in a certain amount time, dont worry about tork, in other words, if you have horse power from 2000 rpm to about 6300 rpm, and your high horse power peak is 6000 rpm you want to match your rear gear ratio at 3.00 would be close to the peak for a top speed of 152 mph, everyone talks about tork now because its politically correct, also the rear gears like 4.11 means your drive shaft turns 4.11 times to the wheels 1 time in automatic 3rd so your top speed and mileage drops, so your car will be very quick but top speed drops but unless you have slicks there is no point in the 4.11 type ratio, because you cant floor it off the line anyway, you will just burn rubber because your too close to the higher point of the power band.

No way of answering without knowing overall condition, originality of parts, etc.

go to manheimgold.com and figure it out.

The American Antique car club and most insurance companies consider a car eligible for antique car insurance after 25 years of age. Using this standard, the 66 Pontiac GTO would have been considered an antique in 1991. Many states have their own regulations with regards to what is considered an antique, so be sure to check government standards in each state.

From the factory it was rated at 400 horsepower.

10w-30 in either synthetic or regular oil will work fine.

probably the same place as on the 66 chevelle as they are both A-bodies, the washer bottle is on the drivers side right next to the radiator and mounts in a holder that is bolted to the radiator support.

339 Convertible WS6 Trans Ams were made in 1998. All WS6's have ram air.

sure y not

In order to drain the radiator on a 2004 Pontiac GTO it is necessary to pull the lower radiator hose off. There is not a separate drain plug on this radiator.

Just call any insurance company and ask for a quote...they will give you the quote for free just because they want your business. All you have to do is give them your information....car info, your driving record info so far, etc. I bet it will be pretty high though because men usually have higher insurance rates, ESPECIALLY if they are under 25-27, and because that is a sports car...

Depends on the year

Iron Intake to Iron Heads - 40ft lbs

Aluminum Intake - 25ft lbs

Vehicle Identification Number.

Either a 5.0L 305 or 5.7L 350 V8

That all depends on the size of the rearend itself, the 3.46 gear has nothing to do with it.

I believe the tissue holder goes to the right of the console on the passenger side.

4.7 sec 0-60 mph
