350 with edelbrocks?
I have a 350 inch pontiac motor and 72 cc edelbrocks. The edelbrocks have a 2.11 intake and 1.77 exhaust valve. Can these heads be used on this motor? I heard the heads could be used if they had 1.66 exhaust valves. What do y'all think?
Also, I have had a built 406 for over 7 years. All those years it's been hammered, like 6500 rpms and it went 11.9. Anyhow, about 3 years ago the block froze and cracked, yes, the good old water insted of antifreeze. I didn't know where it was cracked until about 5 months ago when I removed the valley cover and saw it. It was a front to rear crack 2 inches from the deck between the center lifters on the drivers side. The car ran just fine until I discovered WHERE the crack was, it just ran out of coolant. Well it startes munching cam, 4 to be exact and the last cam I tried to use mobile 1 symthetic. Thats when the car got really bad. It started knocking and I pulled it apart. There were flakes of copper in the oil pan. But all that to say, when I removed the hardened oil pump pushrod I noticed that even though it was covered in oil, it wasn't slippery. My fingers actually stuck to it! The same with the timing chain. When I held the set up by the cam gear and rotated the gears like I was turning a steering wheel, the bottom gear sort of stuck to the chain. Like it was magnetic, it didn't let the chain go freely, the chain stuck for a second then let go! So weird! So i don't know if the antifreeze + mobile 1 = liquid sandpaper or what? So the new-to-me engine is getting rotella T. I don't know what other motor oil is worth more than 2 craps. What do y'all think?
