L-72 Dyno Test

[Keith Tedford]

I was surprised that the engine made advertised horsepower with the stock exhaust manifolds. These pieces were a bottle neck. The value of fine tuning was also quite obvious. It would be interesting to see a run on the engine with headers. You aren't going to be driving on 112 octane gas all the time so how would the engine run on 92? As for the 2" spacer, it is not going to fit under a stock '69 Chevelle hood. The breather almost touches now.
