Hey Guy, Thanks for your replies. Bill, you have an 81 and you know those heads were the cause of the stock 185 hp. I had never seen such restricted heads before. As far as the folks from Promaxx, I expected they would not replace the heads, I was not looking for that. I was however looking for...

Hey all, I have not posted alot on the forum but I read often. You guys are great! I need to vent though. I purchased a set of Patriot heads about 2-1/2 yrs ago, then the problems started. First, I could not fit the rocker arms under the stock valve covers as they interfered on the intake...

Thanks Andy,,,,Sensei is the member I spoke of in the first post. I have read about his accomplishments and after reading a story about some heads that was posted, he is a stand up guy!! I have read alot about the qjet but experience is worth more than all the books, that's for sure!!! Thanks...

Thanks!!! Thanks Steve, I am unfortunately an old time chebby guy as well!! I think the vortecs might be the best way to go for the low cost, I do realize I need the intake, I am just hoping for the high 200's on hp...but as I said, after looking at that head, I can see why the 81 is a...

It does sound logical that the movement at 9 and 6 could be at those points, especially if everything else was real tight. But still, you are saying this is still happening after an alignment! I would think the alignment guy would have caught that!!! When you test it again, pay very close...

I am just wondering what was moving in the front end when you where able to move the wheel 1/2" at 9 and 3, which is generally in the linkage, 12 and 6 is the ball joints. Just a thought, the alignment guy checks all the things mentioned in previous replys, but not the steering column, could it...

Hi All, I now have the engine out of the car and I am trying to research the best way to get a bit more performance from this motor. I would like to keep the A.I.R. system online as it does not seem to matter too much if it is removed. I am not trying to set the world on fire, just tryint to...

Tiger,,I agree, it is state to state, however, in PA my 81 only requires a visual inspection to get the sticker for the window if you have tha car registered like any other car. If you go classic or antique, you do not require an emission sticker on the windshield and thus no smog stuff. Check...

It helps if you remove the gill vent as well, you can reach right up and grab the fan motor from that acces point! It is a pain to get them out,,,sorry!!!

I started a new thread to keep all the great answers and opinions in one spot,,,Thanks much in advance!!! Here is the plan; 1: I live in Philly, change to classic and junk all the emissions components. 2: Pull the engine and have the lower end reworked. Now, the fun part,,,Camshaft?,,Intake...
