[PSJ]

Engine - 1979 Lotus TwinCam 1598cc Big bore, tall block (crossflow) built by vegantune (120-130bhp).

Have had the head of and not sure what cams are in it!? Can anyone help.

They have these numbers Below stamped on them.

MC25011 - 26 E 351 - D

Thanks, Piers.

MC20511 is the casting number used by whoever cast these cams originally for Lotus
26 E351 is the lotus cam part number
D should represent the D type cam which was the sprint cam specification which is
272 degrees seat to seat duratrion and 0.360 gross cam lift above base circle

Does it have 2 grooves on the sprocket mounting flange which was the standard lotus marking for this cam?

Thankyou rgh0

Erm I'm unsure as I never took the sprocket off. Iv sent the head and cams away to get sorted so I will get confirmation later this week.
