Big Block vs Poly

I am a big fan of both engines.A budget stroker 400 will give you 451 cubes. A stroker poly 318 gives you 390.Both short blocks will cost about the same to build,,BUT you are at a + 61 cubes with the stroked 400.11 years ago we did the 451 stroker with Edelbrock heads and a mild 490 lift hyd cam.Drove the car on the street(65 Belvedere tremic 5 speed 4.10 gears) put 30,000 miles on it in 2 years,put a 727 in it and went drag racing,3800+ lbs ran 11.90's in street trim. That engine was transplanted into a 73 'Cuda in 2007 and is living happy ever since.
Now the poly 318 would require much more money to build with the intake costing over $600 alone. You may be able to find something used.Poly head work may surpass the price of aluminum BB heads. Doubt if the early B TTI headers will fit in a A body,,,But it sure would be different when raising the hood.I have a friend doing a no expense spared Poly now to put in his 64 Dodge "B" wagon.Why ? He has had just about every Ma Mopar engine combo in different cars and Poly is the last on his list to do.So bang for the buck the 400 stroker wins for me. Just thinking out loud....
