Hello everyone,

i have a question about the engine numbers of the early TVR's with Ford V8 engines.

How are the engine numbers of the Griffith 200 / 400 and the Tuscan V8 to be interpreted? Attached is the engine number of the Griffith, which is currently for sale at BAT, as well as the engine number of my Tuscan V8.

Griffith 200 / 1965: 1368-613 KC
Tuscan V8 / 1968: 1490-28 KC

Does anyone know how to interpret the individual numbers? What does the KC mean, which can be seen on both badges? Does the numbers bevor and behind the hyphen have anything to do with the order of the engines used? Has this anything to do with the performance differences? The Griffith was probably available with 200 and 271 hp, my Tuscan is said to have 306 hp.

I am grateful for every idea,
Michael

My father's Griffith had a 289 cu in (4.7l) Hipo engine.
His Tuscan V8 had a 302 cu in (4.9l) engine.

The engine number bares no relation to any ford sequences for engine numbers and will be stampings invented at TVR.
Early Griffs will have 289. Tuscans will have late 289, 302 0r even 289 built using 302 blocks as was the case at ford through 67, 68, 69.

there may be factory build info linking a TVR stamped engine number to either standard or Hi Po. the easiset way though is to look at your cylinder head under the valve cover to deem whether it is a Hipo engine or not.

Michael, to what end?
Are you considering changing the performance characteristics of the engine?

There are decent web based resources describing where to find casting numbers on SBFs, and how to decode them. HiPo blocks are identifiable via those numbers.

Probably C5AE-A, if it's a "high power" (HiPo) version produced between '65 and '68.

Unless somebody swapped in a standard short block, under the HiPo heads. Or rebuilt the engine using non-HiPo components. Or unless they're rebuilt standard heads, on a HiPo block. Or . . .

Could check the heads the way Neil suggested, and then verify block casting numbers and also get a dial indicator over an intake and an exhaust spring retainer, and get some cam info. That could yield additional useful information.

On the other hand, the only way to really know what you have is probably to open it up.

Best,
B

Unfortunately, my request was not understood correctly. It's not about knowing which engine I have, but only about the meaning of the engine numbers assigned by TVR. Were these "rolled" by TVR at the time or is there a system or further information behind it? In any case, the TVR numbers have nothing to do with the original Ford engine numbers (are much longer).

Of course, I will leave the engine as it is. It is a HiPo motor with appropriately marked heads (289 & 2 dots), the block has the marking C5AE-6015E has the thick balancer and the crankshaft is marked accordingly. In this respect, the engine is an original HiPo.

Only the attachments differ from the 'normal' HiPo with 271 HP: Holley 715 cfm, Cobra High Rise Intake, Long Tube Headers etc) this version corresponds to the Shelby 350 GT Mustangs with 306 HP.

In later brochures, this service was also stated for the Tuscan V8.

Everything should stay that way, I won't change anything, only the engine gets an overhaul, as it has stood for 40 years.

So I am only interested in what the individual numbers and digits of the engine numbers created by TVR mean. Maybe someone knows that .....

Thank you very much!

There used to be a TVR archivist. Oliver, possibly? Not sure. Have you tried reaching out to him?

Have you asked Mike Mooney https://griffithmotorcars.com/ ?

I assume that he might have further knowledge of any Griffith engine number system.

PS: I have ever though the engine numbers were given by the engine suppliers, is'nt that the case?
