Bradan 550 major service

Dan, Michael- Should be nearly a brand new Maranello when finished. Excellent workmanship.

 

Curious about welding the drive gear fences.

 

Spot welded?

 

Looks like I have no choice but to send my car to you guys..its a long way but who else is going to get into this level of detail!

 

Are there any camshafts available for these engines with higher lift and/or duration, or would one have to go with a custom grind? Up to what lift can you go with stock valve springs and piston-valve clearances? Thinking of power-adder possibilities, but it seems like very few people mod these engines, other than what Prodrive did with the 550 race cars.

Awesome thread, thanks for posting!

 

Put Fabio's 6-1 headers on her if you want some quick hp.

 

No doubt about that, Taz. Probably the single best bang for the buck performance mod one can do for these cars. Still, I'm curious what other engine mods are possible, such as cams and cam timing, and/or custom programmed ECU, to realize even more power potential from these magnificent engines.

 

How much of a bump do you think the car see from having high flow cats put on?

 

Notice DIY'ERs! Camshaft cogs off and camshafts off heads during service.

 

FBB- As you know, you have to do that on a 550 to change the cam seals and Dan even does it on 575s (and 550s) so he can clean the hydraulic lifters. On 575s, you can change the cam seals without removing the cams.
