Firing order

Saw the yellow MGB GT V8 at Spa last weekend again. A very fast car and a very good driver. 3.9 with 4 Dellortos DRLA 48.

The winner of the SPA 6h was a GT40 with Wright/Gans/Wolfe best lap time 2:47

The winner of the British Sports and Saloon car comp. was Russel McCarthy with his MGB GT best lap tim 2:47!!!!

BTW he has a special crank/cam combination and has a firing order 14527638. Normaly it is for Buick/Rover 184356572 as long as I can think. He says less vibrations and better gas flow.
On the dyno 390 BHP!! Hart to belive but if you see the car racing you promptly agree.

Never heart about that firing order. Just know that you can choose 2 different firing orders on Ford depending on the cam but with the same crank.

Okay so now the experts.

That's a flat-plane crankshaft firing order I think which will give better exhaust tuning and higher max engine speed, but with more vibration.
