750 Veloce Header Installation-Need Advice

1722 Views 12 Replies 4 Participants Last post by  richs
Well, I got the engine/trans unit in the car (1959 750 Veloce Spider) and it seems the exhaust header has no way to get it into the engine bay to mount it without taking out some of the brake system. Any suggestions? Thanks, Rich

Yes, The headers need to be laid in place BEFORE the engine goes in.

Solution is to remove said engine or cylinder head or pedal box ( I think that is one solution but can't swear by it).
Wish there was a manual that actually was helpful to assemble the bits. Getting the engine in was a bear. Most difficult was the engine last engine mount. I actually pulled the engine mount studs from the engine, maneuvered the mount in place (not easy) and then put the studs back in. So that's not coming back out again, hopefully ever. Your suggestion of pedal box removal seems the least amount of rework. I'll try that first. Thanks for the suggestion. -Rich

Alfa came up with a fix for the motor mounts. Instead of two studs going in the frame keyholes the rubber mount has just a threaded hole to receive a bolt.. It helps when changing out mounts too. I think that is how they came up with it.

I know some early cars were difficult to get the centerline straight on the installation, but it should have been okay on your car. A little bit of axel grease on the face of the mounts should let the whole thing "glide into the bottom of the keyhole....After a 400 lb gorilla stands on the engine.

Interesting. Often wonder how they can build these cars in any consistent volume given the quirkiness of the assembly. Years ago I saw a Lambo engine being installed at the factory. Some choice words in Italian and the crow bars came out. A few moments latter a large boom, and the engine was in.
Let's hope I don't need to rent a gorilla... Or another 240 pounds to add to my 160. Still going to go for teh pedal box first. -Rich
I have installed the headers with the engine in the car. Install them from the bottom . I think {?} 1&4 first . just lay them in - don't bolt them - then 2&3 . Two people is better , one on top holding them as you fiddle them into place. As stated the best way is to lay them in as the engine is being installed.

Too late to install with the engine. I spent 20 minutes trying all methods to fiddle with it. Looks like the brake 4 way union is the only part in the way. It's on teh agenda for Saturday. The pedal box may not need to come out. Will advise once I get it in... Thanks for the suggestions. -Rich

Ron has it right according to the shop manual. Kudos. Thank you

I never had a lift.

Book says "Working from the bottom slip off the narrow (2+3) tubes first, the the wide one (1+4)" Install in the reverse order.
It is possible to get the manifolds on whilst the engine is in place. It is a fiddle but I always remove the studs from the block which hold the engine mounts and Helicoil the holes. Then you can shuffle the engine from side to side and get the manifolds in place easily and, to be frank, it makes fitting the mounts with cap bolts easy too.

I removed 2 brake lines form the brake union block and wiggled the headers in. These are new repro's, so when finally in, the flange on the inner header seems angled a bit. I might have to bend the flange area about 10 degrees to mate with the muffler section. Seems not much anything actually fits on these cars. Welding torches are the new hammers... Thanks,Rich
A friend of mine who has been around the horn (77years old), usually spends a few days on installing an exhaust system. He is a sticker for perfection and must take any stress out of the whole system before he is happy. Heating some pipe cherry red gets it done for him.
He is correct. I have a torch!
