Sorry didn't explain properly, he's first put an engine no down as s46 or somethin, and shows a pic of it stamped near the dipstick tube, which is where I thought the numbers were stamped. The other no he had he found on the front somewhere.

S46D is 4.6ltr based as fitted to morgan, (same as my 4.6 is stamped)

i think the 5.0 uses the same stroke as 4.6 but has a 95mm bore.
instead of the 94mm bore.

heads look 4.6

compression 9:35 ??? morgan ?sounds 4.6 and crossbolted again 4.6
looks to me a 4.6
in 1996 morgans had option as 4.6 9:35 1 compression??
it shows a 4.6 engine number as per the numbers on one of the pics

S46D0000A Morgan +8 9.35:1cr efi
37A50P0000 TVR Griffith/Chimaera 500 10:1cr efi

When you swap a crank/rods/pistons into a block the original stampings don't change magically

Same when you pop some other heads on, the CR can change... If its just a TVR that had a bad block, then they could have used any 94mm block (5.0 is just stroked) - in fact some may have done it just for the x-bolting? TVR power have also been known to rebuild other peoples motors to 5.0 spec - so it might just be a bottom end, but since it came out of a TVR its is more likely to have the proper heads as well.
