Hello,
porsche 911 camshafts BM 620 9. and here it is probably the shop BM ? ok long time ago !
And heads have marking IMS, the shop ? and the date I think 12/90,, this is how we do !
Is this something somebody knows what shop made this? built on a 3,2 Carrera case 3,4 L stoke 74,4 cylinder 98 mm, it was running well but was built in 1990 by somebody in Boston as what I think? MFI pump set up by Gus in LA
Twin plug compression 10,5 and that was good on all cylinders, but the car had been standing for a long time.
So it is a bit off-race and street engine fun to drive, but as you can see it was time to rebuild as the camshaft lock is good in my eyes but just these numbers on them!
As you can see on heads and other stuff, it was time for a refresh! stamps 12/90 and the shop maybe
Thanks
