Re: cam timing off?

Aha! My thinking didn't account for the reduction of lash when the engine was warm! My observations were done with the standard gaps on a cold engine. The car ran quite well before all this, it had good power and torque with very little smoke. Nothing lead me to believe a mis-timed cam but I've been...

Re: cam timing off?

I know I'm talking to myself but here's some more info: I checked cylinders #6 and #7 and surprisingly they too showed the same late inlet opening as #1 and #12, about 18 degrees BTDC instead of the 27 degree BTDC per spec. When I say "late" I mean later than spec, not later than TDC. I also double ...

cam timing off?

Ok, you can see from my subject line I'm questioning my cam timing. Here's the set up; valves clearance checked and adjusted on #1 cylinder, naturaly at the proper TDC, verified by the rotor position. Both valves were pretty good at .006 and .008 but I readjusted them anyway after inspecting the adj...

TDC confirmation

I'm preparing to inspect the valve train, adjust the valves and check cam timing. My engine has probably never been apart, do I need to confirm that PM 1/6 on the flywheel is truly indicating TDC? If I do need to confirm true TDC by actual piston travel is it possible to get a good indicator reading...

Re: Warped carb base

I appreciate all the responses. Of course my first instinct it to repair things myself, I guess it is for nearly everyone here, but I can see that it could be costly to practice trial and error on somewhat rare Carbs, 40 DFI /2. and after talking to Mike at Pierce I decided to have him do them....co...

Re: Warped carb base

We all know the warped carb base syndrome is very common on carburetors that use fiber or phenolic spacer on the manifold (not just Ferrari) This warping occurs when the spacer compresses unevenly because it is a soft material. Ok, now what? will people continue to warp carbs forever? or is there so...

Re: Warped carb base

Ok, I talked to Mike at Pierce about my carbs, albeit expensive ones. Surprisingly enough the car was running quite well before I decided to inspect the carbs, but I'm glad I did before they got worse or caused me headaches down the road. Ok now the bad news, the lead time is 10 weeks! but this will...

Re: Warped carb base

My carbs are currently at Pierce Manifolds and have warped bottoms as well. I am no expert at this, but after touring the shop and seeing what they do, I knew I was out of my league and let them do the work. Mike Pierce tells me he gets a lot of carbs where people tried to bend the tabs back straig...

Re: Warped carb base

Hi Collin, thanks for the reply, what harm are you thinking of? Breaking a flange off? Are the castings that brittle? I'm thinking to straighten out about half of the warp and finish mill the remainder. I dreamed up a fixture that would consist of two thick pieces of steel, say 1.5 inches thick, mac...

Re: Stamping a Label

I'm sorry I can't suggest a source to get it done but steel stamp sets are not usually expensive, the trick will be to find the right font, it looks like you need a star too, which is not so easy to find. I just looked at my serial number tag and it appears a stamp holder was used...very straight an...

Warped carb base

I decided to remove my Carbs for some restorative work, right away I checked the bases and they are warped, I've only checked the first one and it will take a .024 feeler gauge when a straight edge is applied. I know I can put it on mill and spank it but it seems like a lot to take off. Has anyone e...

Re: speedometer drive

C. All removed as in picture. Internal gear spinning appropriately with no marred or missing teeth. As I put it back together I was able to insert a small flat screwdriver into the piece protruding from the overdrive unit that the angle drive screws into. I then spun the driveshaft with my left han...

keys and locks

Does anyone know if there is a go-to guy for 330 keys and locks? I am missing the key to the glove box and the trunk release, I'd also like to get a proper key for the ignition. I know I can probably hunt up the blanks and find a local locksmith but I don't want to spend the time unless I have to. T...

Re: Correct Spark Plug Boots for a 330 GTC

Ok Steve, your description does sound like the old Bosch connectors for Porsche, they are somewhat long to reach into the recess. I'll also be changing my wires and connectors soon. Not many folks know what is original on these Ferraris, unlike the old Porsches where the experts are legion and highl...

Re: Correct Spark Plug Boots for a 330 GTC

Steve, do you happen to have a photo of the terminal connectors GT sent you? I'm very familiar with the Bosch/Porsche item but wanted to see what GT thought was correct. Ironically when I decided to get out of the early Porsches and into Ferrari I liquidated at least 50 of those brown Porsche connec...
