Whats a man to do ??

Get a service manual with a wiring diagram and figure it out ???

Bill,
There is probably something else causing the problem. How are the plugs and wires ? Are you using GM rotors ?

I just changed all of the original parts on my 99 Tahoe last spring with 245K miles on it all. I have not heard of anyone having any problems as long as they use GM parts.

Lewy,
There is an AERA bulletin that basically says you can reuse the bolts as long as they are not stretched and there is no thread damage. If you PM me your e-mail address I will send it to you or you can have your machine shop print it out for you. It is AERA TB 2141

Intake or exhaust valve ? Which Manley valves ? If I was going to use Manley they would have to be the severe duty ones. If I had a choice I would use Ferrea I have seen them literally bent like pretzels but never broken.

That engine needs to go on a dyno to see what the problem is.

No bashing here. That is the only way to know what you have as a starting point.

Maybe it is something crazy in the heads but I sure cant tell.

It has to be. I have used those blocks for flat tappet builds and not had an issue.

What lifter are you using to check with ? That being said if the heads were used on a circle track engine and you have no idea what has been done to them you simply need to go with what you have. Circle track guys are known for doing some crazy stuff to heads and then making them "look" like nothing...

Yeah called and left message.
I have tried Darton as well as LA Sleeve 6-8 week wait for custom' sleeves

Dave,
Did he get back to you ? He has always been very good about calling pretty quickly. I need to call him in the morning and order a sleeve for an engine I am working on.

Is that the full name of the place ?? A search reveals 100's of options.
Do you have a contact number?

http://powerbore.com/ Thats who I have been using for sleeves for several years now.

Travis,
Call your machine shop and ask them how they want them. Some of the DIY chemicals can play havoc with hot tank and spray wash chemicals so you might be making a problem instead of helping them out. I would scrape as much off as you can and let them do the rest.

New pins are for spirolock and squared off on the end so they should be ok as long as they measure the same. That part does not matter because if you are press fitting them you are not using the pin locks anyway. Do yourself a favor and do not try to press the pins in unless you have a fixture that...

However the data on this pin says it is for spirolock applications only. Blue, I would call Manley to make sure but if I had to guess I would bet that is says that to make sure the pins were not used with the newer round wire type of locks which require a chamfered pin end. I have used a press fit ...

I have one customer that has me mill them all to 9" deck hgt and as far as I know he does not have any issues with intakes. I would think that .087 is definitely going to cause a problem. If you dont already have pistons I would think it would be a lot easier to just get the piston you need. Most of...

Steve, I have seen one before that a customer brought in. He had used a 9 keyway crank sprocket and you could see the indentation of all of the cutouts all the way around the crank and that was exactly where it broke. Same deal as someone else mentioned, not enough chamfer on the sprocket to allow i...

And you will also lose a lot of compression because of the larger chambers on the 350 heads compared to the 305 heads.
