Lost the camshaft woodruff (?) key for my ATR RP309G camshaft when the engine was torn down. Does anyone know the part number and where I could get one? I think the term is woodruff, but not sure.

My machinist sent out my ATR RP309G camshaft for re-grinding/cleanup. Two lobes were pitted a bit due to some foreign material circulating around. While my Turbo Trans Am engine is apart, I would like to purchase new timing gears. Because this is an old stick, commonly available gearsets with...

Bought a modified '87 GN 2 years ago with plans to do more upgrades over time. It ran fine for about a year, then a problem came up out of nowhere. Iin Feb '19, I was doing an easy 45 mph cruise after fueling up at a gas station. After 2 miles, the engine started missing very badly. A/F went...

Does anyone know the gasket thicknesses of a Fel Pro 70032 or Mahle B45577 oil pump cover gasket? I can't find any specs for these. I need to buy a gasket that is 0.006" thick to match the one that I need to remove. If you have another source, manufacturer or part number to suggest for a...

I have a used 109 block, stock cast connecting rods, forged pistons and a factory cast crankshaft for sale as a parts package. I recently disassembled this short block which was in a running car 6 months ago. All parts were still in good shape. Only the front cam bearing showed some wear...

Bought a DW400 pump. As advertised, I can confirm that it does not have a check valve like other fuel pumps. This results in extended cranking during startup. Looked on Jegs and found the following: a. Russell (Jegs part number 799-650603) has -06 AN fittings, $29.95 b. Dorman (Jegs part...

I have a 3" downpipe on my 87 GN and would like to split it into dual 2-1/2" pipes at the cat flange to make the rest of the exhaust sytem easier to fit - especially over the axle. Using 3" pipe past the split is unnecessary and creates body and suspension clearance problems. Does anybody make...

Sorry if this has been posted before, but I couldn't find it. Apparently Holley has bought Accel. The Accel web site pages where I used to be able to download CALMAP software now redirect me to Holley - and the Holley page does not have the software or even acknowledge GEN 7+ as a product. I...

I am changing to a set of low impedance injectors from Accel, part number 74616. Does anyone know the injector delay time/rise time for these? One of the Greg Banish books says that typical rise time for low impedance injectors is 0.2 ms to 0.4 ms. But I'd like to know the real number for...

I am experiencing frequent false knock (even at idle) on my Casper's gauge, so plan to replace the knock sensor with a new one. How tight should the knock sensor be in the block? Is there a special procedure? Best, Bob

I currently have 55 lb injectors in my engine and an Accel GEN7 ECM. Last year (with a cat converter) by tuning A/F and spark, I was able to pass emissions at 15 and 25 mph on a rolling dyno. It was pretty tough, but I did it. I was thinking that when I have to do this again some day...

Aeromotive now sells 11140, 11141 and 11142 fuel pumps with 30% more flow than a Walbro 255 lph that can be mounted in-tank. The 11140 has both the inlet and outlet centered. The 11141 has an offset inlet and a centered outlet. The 11142 has both an offset inlet and outlet that are...

My car leaves the line very gently – no snap - like there is no accelerator pump. My logs show lean conditions when I open the throttle blade to leave the line. I fooled around with the TAU vs. MAP ECT screen. Changing some of those values helped a little. I also tried messing with the TPS...

I have pretty lousy idle quality and a frequent stalling problem when coming to a stop after cruising for a while – unless I double foot the brake and throttle. I’m only pulling about 16” of vacuum at idle (engine warmed up of course). I have my idle A/F set at 14.55 to 1.0 (closed loop...

Here I am playing around again with aftermarket parts that don't seem to work together. I have a BHJ balancer and a brand new Chinese crankshaft. When I put the balancer on and torqued the retaining bolt, the teeth on the sensor wheel are in too deep and are physically contacting the...

When looking for some replacement rocker arms, I checked NAPA and Summit. Both list Sealed Power part number ZR947. That can't be it as the pictures show a shaft mounted rocker arm - probably for a Buick I'd guess. 1. Does anyone know the correct Sealed Power part number to order for our...

When I took the exhaust off of my TTA, I found that the exhaust manifolds were (poorly) sealed with orange RTV only. No gasket. I am building a new engine for this car and am having trouble locating exhaust gaskets. It's interesting that the TTA Service Manual Supplement does not even...

Bought a pair of valve covers for a Turbo Trans Am engine that I'm going to store. I was able to use paypal and the covers were shipped promptly. It also helped that before buying turbotre posted pictures of the items, so that there were no surprises. I am satisfied with this transaction.

I had this thread in Buick engine tech, but solid answers were not forthcoming. I want to store a turbo 3.8 engine in the corner of the garage and would like to buy a suitable engine cradle/frame with wheels. All I see at places like Summit Racing and Jegs are cradles made for V8 engines...

This could be an easy one. I want to store a turbo 3.8 engine in the corner of the garage and would like to buy a suitable engine cradle/frame with wheels. All I see at places like Summit Racing and Jegs are cradles made for V8 engines (like Chevy and Ford). I am unfamiliar with the...
