Serial no for Chim engine

[GREYHEADGIT]

Does anyone know where the engine no's are located on a '95 Chim engine block, as I have a 450 badge on the back and on the plenium cover, but the V5 says 4.0. Dont want to be caught out by insurance company not paying up if, god forbid I get a prang.

It's stamped into the block top face, just behind the dipstick.

The engine size is also encoded in your VIN plate, a search on here will yield the key to deciphering it. IIRC some 450,s were coded as 430's re engine size.

The proper Tvr engine number will be stamped underneath the pas pump housing in the cylinder block face.

If its a 4 litre it should read something like 37A40Pxxxx if its a 4.5 it should read 37A45Pxxxx

Hi Jamie, my block has the 37A40Pxxxx bit stamped over the top of the original engine number and compression ratio next to the dipstick. Has something fishy gone in the past or is it more likely to be a "typical TVR"

Hi Iain,

They *should* be stamped in both places, and more often than not they are, but sometimes the number can be missing from the face by the dipstick hole...this could be for a few reasons inc if the block has been skimmed in the past. You can pretty much say that the number by the pas pump housing is always gonna be there though.

That's what I'm saying mine doesn't have the PAS stamping, only the "over-stamping". I must have one of the slow engines then, I knew it couldn't of just been my driving.

Same, mine doesnt have the PAS stamping...but then mine doesnt have PAS (mans car, not a girlie one!!! )

[GREYHEADGIT]

CAN'T SEEM TO FIND ANY NO'S AND MINE DOES NOT HAVE THE PAS. SO WOULD IT HAVE IT STAMPED IN THE AREA THAT THE PUMP SHOULD BE. BEEN LOOKING FOR A WHILE WITH MY TORCH AND NO JOY. WIFE THOUGHT WE HAD BURGLARS AND CAME AT ME WITH ROLLING PIN. GOOD JOB SHE RECOGNISED MY FEET!!!!!!!!!!!!

From what Jamie is saying there should be a number somewhere around here


however as noted its sometimes not there.

As Jamie said they should all have the numbers stamped on here, every engine that was built in Coventry had the engine numbers stamped on here by the engine builder who built the engine, hence the mess that was made of some of the numbers that were stamped on them, as it was oftern the case for stamps to be hit incorrectly and flying across the build room.

It should be under the PAS housing on the block , even if you do not have PAS you still have the housing with the pulley and it should be under that on the block just under the cylinder head.

I dont have the PS block but have just checked - sure enough uner the left bank on the face of the block there is a stamped number...and the main engine number is overstamped on the original...

Having looked again in the area mentioned, can only see no on the head which says RR4323, does anyone know if this no relates to anything to do with the type of head fitted onto a 450 engine??????????
