After many band aids on the stroked GT-6 engine that's in my '74 TR-6, the oil pressure has finally gone to low to put it off any longer. I picked up a '74.5 block two years ago. It's at the machine shop, and looks pretty good. The questions:
Cam bearings? - I will be using a more agressive cam, and was planning on cam bearings. The machine shop says the existing cam bores are in excellent condintion and can be used as is. The head was rebuilt last year with 9.5:1 compression ratio. Are the cam bearings worth about $400 in labor and parts?
Headers or stock exhaust? - Moss has a 6 into 2 header for about $420 plus coating plus welder for installation. I've heard this can gain up to 10 hp. It can also be done later. Is it worth it?
Cam? - I'm considering the TSI TSI275-6 or the GP2 cam. Anyone had any experience with either cam?
Timing chain? - Anyone know of a source for a heavy duty chain? The gears were in good condition.
Pistons? - Are AE worth the extra money (over County)? I'll be going .020 over.
I've got to pull the existing engine to provide the flywheel and clutch for balancing, so it will be a couple of weeks before I do anything. I'm sure more questions will be coming. Thanks for your help.
