I have owned the car since 1993.

I am mocking up my "new" combo on the engine stand, and have discovered an issue with lifter body clearance with adjacent lobes on the camshaft. I am using the Comp 210 hydraulic roller with PBM (Morel) lifters. On a lobe or two, I have slight contact with the adjacent lifter body. The...

Guys, I am going back together with an engine here, and I was wondering about the main bearing choice. With a stock crank, would a race bearing like the 107m's be a better choice than a stock replacement FM bearing? I'd appreciate your input. Thanks, Counterman.

Guys, I am taking the plunge and going roller post flat tappet cam failure. I just ordered the 210/215 Comp roller from FT. I have ported Champion irons with T&D 1.55 rockers. I am running .030 over Speed Pro forged slugs in this motor. Has anyone had piston to valve clearance issues with...

Guys, I am going to pull my engine soon, again. I am going to convert to a roller cam and check my bearings for damage post flat tappet cam failure. I am trying to avoid pulling the trans and draining the fluid, etc. if I can. Last time, I pulled the pair together and sent the trans to Mike...

Guys, which vendors are supplying the Morel lifters in their hydraulic roller cam kits now? I am interested in getting a kit with the new lifters, and would appreciate your feedback. Thanks, Counterman.

What size valves are used in the Champion Iron heads? I seem to recall that they have Manley valves, but cannot find the sizing. Thanks, Counterman.

I have been chasing a miss in my recently rebuilt motor. It appears to be getting more pronounced, and it has started popping at 4k or so. Idle quality is going away also. I verified 150psi in all holes today, so no bent valves. I pulled the valve covers and cranked her up. Exhaust pushrod...

Hey, guys, I am in the process of putting my car back on the road after being parked for several years. This is a fresh rebuild with billet caps and flat tappet cam. I broke in the cam per instructions, and things look ok. All of my pushrods are spinning nicely, so I think I am in the clear...

The flexible rubber baffles behind the grille that direct air through the radiator instead of around it are looking rough and dry rotted on my car. What are you guys using for these? I reckon that something from Lowe's or a hardware store could be purchased and trimmed to replace the old...

Guys, I am planning on getting a set of drag radials for my GN once I get my transmission back into this thing. I am running 235/60 Goodyear Eagle street tires right now, but they are useless under boost. I see that plenty of you are running the 275/60 on these cars, but they are a tight fit...

Folks, I just yanked my pos 200 from my GN this morning. It is suffering from a poor local rebuild, and it has not been right since I put it in. As if to prove to myself what I knew was a bad idea, I bought a load of parts and had my local "performance" guy do the build. Yep! That WAS a bad...

Guys, I pulled the pan on my trans today searching for a thrown governor spring. I found a spring in the pan, but the governor spring is still in place. It is a light spring about 2 inches long that compresses down to about 1/2 half inch. It is maybe 1/4 inch in diameter. I have found no...

While redoing the head gaskets in my 87, I noticed that the intake has a hairline crack running from one of the ports towards the center of the manifold. It is a ported stocker from Champion, and has maybe 50 miles on it. The crack is nowhere near a bolt hole location, and I am wondering if...

My bastard transmission caused an unexpected downshift into 2nd at wot in 3rd, causing a boost spike and over rev to the limiter. The car popped, then started right back up. Afterwards, I noticed an elevated water temp. The car would not run over 180 before the incident, but it wil run 215 or...

I just had a local shop rebuild the BRF 200 4r in my 87, and I cannot seem to get this thing to work right. I am aggravated because I tossed in lots of goodies from CK and PTS, amongst others, and it is behaving poorly. It is an original 56k mile unit that was flairing on the shifts pre...

Guys, I have just purchased a new Tial 38mm external gate and new 3 inch down pipe from Cotton's to take the place of some old ATR stuff that I had. It came with two loose springs, one already installed, and a pack of washers to shim the springs as needed. I also have an RJC manual boost...

I just reinstalled my freshly rebuilt 200 od in my GN, and, of course, I am having trouble. I had it done by a local tech who has a good reputation, and does hp stuff, too. In any case, I have good reverse and first gears--no problem. Shifting from park or neutral to either drive or reverse...

I noticed on T&D's website that their roller rockers don't appear to be compatible with the stock GN valve covers. I have a set of the RJC spacers, but have to ask if that will be enough. So, what covers are you using with the T&D's ? I still have the stock heat shield and a/c box, so I have...

After discovering that my genuine Tiawanese Pioneer timing cover was cracked, allowing for a substantial oil leak, I replaced the bad cover with my oem GM piece. No more leaks, but the motor doesn't want to rev. It stumbles when I give it throttle even in Park. Oil pressure is super. I...
