Just my opinion, but least expensive route is to rebuild what you have, or exchange it for a rebuilt LT, so you don't incur additional expense with other modifications and changes.
From what I've read, (and I've only had my 94 Trans Am convertible since August) (I'm 69, and I'll R&R a motor, but won't dig into it,) if it's an OEM vented unit, it's good, but you don't want your water pump to leak on it. MSD and parts store brands are crap, I'm told. There's a company in Alabama called Petris that makes good ones and is highly recommended. If you join LS1LT1.com, there's all kinds of posts on it.Sounds like I'm going to stick with the LT1 lol. Thank you for info, that is exactly what I was looking for! I have no desire to put that kind of work into the car. I will either fix this LT or buy a long block.
I do have one last question though. I am seeing posts everywhere about the optispark going bad and which brands are known to fail. Has that issue been worked out or is there a brand I should stay away from if it comes to replacing it?
You can remove the line from one side of the fuel filter and that will tell you real quick if it's the pump. Right in front and inboard of the left rear tire.Thank you all for the great information. Its nice to be a part of a group that is active.
Just updating you as to what I found today. I removed the valve covers and found one of the valves flopping around. The pushrod was just sitting there. I loosened up the valve and put the pushrod back in the roller seat, tightened it back down and turned the engine over. Everything turned over fine and without noise. The ol girl still didn't start so I checked for fuel pressure at the manifold and had zero.
Tomorrow I am going to troubleshoot the no fuel pressure issue and will give an update.
