Excellent series Culminator.
Very wise to go back to a more standard V8. I have converted 3 race engines back to road but none were as wild as HotMog.
My first was an Elva engine which was a nightmare as it had 10 mm plugs which would last about 30 miles. Good for a race but not far down the road.
The Cosworth crossflow had a big valve head so torque was a real problem.
The Vulcan crossflow engine had high compression, high revs and high sump pressure so smoke signals through the exhaust.
All overcome but much trial and error and engine in and out.
