Engine choice dilemma

Hello Plentywahalla!

 

there's always the light and powerful Renault crossflow engines with more grunt than the Renault wedge head (and it would still appear somewhere near original?)

The Red Top is a superb engine and easily cable of 180 bhp just with weber 45's and a decent exhaust, it was an extremely popular engine in club racing for that reason, even run with a simple ignition system. Very robust and reliable, also if I remember correctly I think there was a Lotus plug cover fitted when they were used in Vauxhall Lotus (Reynard) single seater chassis
