Well, let’s think about it a second. The head issue really isn’t as bad as some of you think. Why?
Small block strokers w/4.00 arms are turning good numbers with ported stock heads and 2.02/1.60 valves. The 361 comes with what head? Valve sizes? And ports out how well?
The problem with this logic is valve placement, a BB has the valves too close to the bore even when using the bigger bore blocks. Look at a BB head chamber through the bottom of a cylinder bore, the valves are offset to one side of the bore then spaced even more to the front and back, a BB head like a 906 or 515 is going to flow less on a 4.125 bore than a magnum 308 or X head will on a 4 inch bore.
I always find it funny when people say an engine is a "TQ engine", what they mean is it wont make any HP. A 361 with a 3.75 crank is going to be one of those "TQ engines".
