Bruce;
I'm familar with the three plugs on the front of the engine you'll are talking about,I have a question..... Do you recommend removing these and tapping the block and using screw-in plugs or are the " factory style freeze plugs" good enough for a performance engine?????? I have heard both ways from different builders,just wanted another opinion.....
I just went in the shop and looked over a 1972 351-W block,it has two freeze plug looking plugs on the side of the cam (front face plate) and one screw-in plug deeper in the block in the front were the
oil drains back near the cam and distributor gear,and one rather large "freeze plug looking" plug in the rear of the block and right next to it it also had a smaller screw-in plug.....
I know you could not tap and thread the large one on the rear of the block,but how about the small ones in the front..... Is it worth the time and trouble or not really necessary??????
