Was having a talk with buddy and he was taking a look at my bucket.
i have a bucket with a nova front clip and and the engine is set back behind the x member approx 24 inches from stock location.
He has a camaro with a bbchevy with the engine in stock location.
my opinion is that the engine set behind the front axle greatly moves the weight towards the rear as there is no counterbalancing of the engine over the front axles.
is there a way to calculate other than front rear scales how much engine setback adds weighh to the rear and removes it from the front. i would guess anything would be a guess as it depends on the egine and car.
