Here is my '77 308 GTB. 4 cam, two valve 4-2 bbl Webbers, aluminum wet sump 3 litre with roughly 240 hp, with an 8 pound flywheel.
The car is about 43 inches tall and the door lock is at kneecap height, weighs in at about 3200 lb, so it is not a rocket, but it does handle.
The spring rate has been doubled, poly bushings, 22mm f/r bars, cornerweighted, BBS 360 wheels and Dunlop direzzionales, (225/40-18 and 255/35-18)
I spent a lot of time getting the brakes balanced. F-50 front Brembos on 355x32 full floating discs with 360 rear calipers, (including parking brakes) on the back 330x28 floating discs. Bullet proof brakes on the track.
Upgrading the ignition from twin 4 cyl distributors with two sets of points to a single distrib with mag pick up and msd 6al & blaster coil, has removed one of the reasons Ferrari's have for fussy expensive maintenance. Using two 4 tube manometers was a big help getting the webbers synced.
Great car, Once had a gal ask me if it was a new mustang :-)
