Cam Swap #2... asking for help this time...
Wow. 319 tq? Is it down a cylinder? I am glad they got it running better for you. I hope you can get it figured out.
What a huge waste of server space this thread has become. The original question has become the equivalent of someone asking "why is my water bill so high?" then telling you two days later they own a water park. Can I get the last 6 pages of my life back please?
No it was definitely caused by the hypothetical 110 LSA.

I would love to talk with the cam grinder, anybody have the card still? Anybody know where is stick came from. Did you know we have seen cams so far in left field it's not even funny. They aren't even the same hole to hole. Cam grinders aren't all the same. One more reason to get in there and figure out why it's so down on power.
Yes it sounds like a 110 LSA camshaft, from a guy that has been in this business for 20 years and racing 20 years before he opened a shop. Doug saw is first LS engine in 1994 at GM in Mich.
So is he able to tell the LSA by listening to the car run or can he actually determine the exact angle at which the exhaust valve opens? I'd like to send him three or four video clips and have him tell me the LSA of each cam in question. I don't know why you even bother asking for a cam card when Doug can apparently tell you the specs simply by using his years of LS experience. Just give the man an index card to write them on.
BTW I am not shop bashing, but to say a cam is on a 110LSA by listening to it is just a ridiculous statement.

This car runs kinda like my 1975 John Deere tractor before I rebuilt it. Cranking on it sounds like it is down on compression, burns oil like crazy. This car had the cam installed a tooth off and broke a piston. Plus many other problems. To bring a car in and make 460 to the wheels with a stalled auto, you better have your poop in a group. Because it's not that easy. Then handicap it without all the other parts to go with it, and you have problems.
Did the other shop hone the cylinder?
Did they lap the valves to make sure the seats were still good?
Is it some welded up head with a seat cocked in there? Did they heat treat the head after welding?
Are there more bent valves?
Cracked guide?
Is the cam installed right?
Pushrods right? Or are they hanging the valve open?
Valve springs close?
Is the cam worth a crap?
Is the 3 inch pretty much wide open exhaust helping?
is the stock un-ported t-body worth anything?
So many unknowns it's impossible to really know why it isn't some super fast internet hotrod. Hence the reason why we suggested a cam swap, because a smaller cam would still reach is goals. Then tear into the heads, double check all these other unknowns..
true... my tune was really only 250-400 tops. but it coulda been rolled into the total engine build so i dunno...
Guys, this is getting out of hand. Seriously, enough slandering. everyone has their shops and everyone has had their issues. i know each and every one of you people scolding at each other, which is why im not taking sides.

Im not trying to bad mouth them the thread starter asked what was wrong with his car. Seeing as mine didnt run well given my past experience with there tune I simply stated that was the problem with my car, when it wouldnt run right is the tune. No bashing was used I was just giving my experience then randy got all mad. If you want people to share good experiences with drm then give them a good experience. Im done talking about this now, o and on a side note my car also was 400 to tune threw them. And I can ask carl what was messed up with my tune that he fixed to get it to idle since it was asked.

This is one of a few problems that we saw so far. Guys really need to start making sure bolts are tight, we are up to about 20 left loose. Torque converter, water pump, cam bolts, and even the hood bolts.
Head flow isn't that impressive at all, actually it's on of the worst flowing heads we have had on our bench...... Thanks guys for the phone call back...........
Yes the LSA was closer to 110 then 114. It was a regrind stock cam and already starting to show signs of coming apart. It was a piece of crap in our eyes and started to wear the lifters in a strange way. No signs of heat treating before or after the regrind. XR288 was stamped on it.
She will be happy sooner then later!!!

So with that said we have no way of figuring out if it's there junk or not.
We need to talk with the customer about the direction of the operation. I would love to replace both with a proven combination that has been rock solid over the years. This package has been on 250+ cars that we have done over the years.

I seriously doubt TEA had anything to do with those heads. From the small amount that can be seen in the pic it appears an amateur went at them with a cartridge roll. You can see the dip where the casting line has been sanded off and the uneven sanding on the lower right corner of the port. I'd like to see some better pics of these bad boys when they come off. what casting number are they?
If they have been poorly ported I doubt TEA did it. It sounds like whoever sold the OP the car took him for a ride and not in a good way.
Scrap the junk he has now and put a proven combo on there. He will be very happy after that.

Hey Randy you better watch your mouth and what you say about TEA, I have done business with them and have NEVER had to leave message after message to get someone. TEA does some of the best work i have ever seen, If you knew TEA's work you would know what to look for on the heads they do, to know it was a true TEA head. With bashing like that no wonder they dont return your calls.
