Could someone tell me what the factory compression height is for a 73 350? I see that Summit has two different pistons from two manufactures and one shows 1.800 and one shows 1.880. That's a big difference. I wonder if one of them is actually for a V6. Thanks
350 Deck height is 10.18. Stock Comp height for the pistons at zero deck is 1.875 V-6 is 9.53 Optimal CD (comp dist) for a 350 piston, with stock rod length, and a .010 clean up cut on the deck, would be 1.865.. according to the books.. your mileage may vary.. I always recommend actually measuring a 350 once the decks are cleaned up and squared. I have seen numbers that don't jive with the books on the 350's.. The 1.800 cd is a short cd for the V-6 JW
