check the transmission oil cooler in the radiator, rare but not impossible to leak ATF into the coolant. an intake leaking coolant usually puts the antifreeze IN the oil and less oil in the antifreeze.
That is an interesting thought. Thanks for the tip. I saw the issue from the radiator as we added water in a previous video and it would continuously push water out of the radiator. To me that says that combustion is making its way into the cooling system hence the blown head gasket. But maybe there were multiple issues like the oil cooler leaking into the radiator. Either way all the issues will be resolved when the engine goes into another vehicle. Thanks for commenting!
Ive always ended up with a bunch of 4 bolts for whatever reason. The only 2 Bolt out of 6 small Block 350s I own is the Budget Build. But yes the 2 vs 4 bolt will be argued till the end of time. I personally don’t care, long as it runs and makes cool noises it’s alright by me.
Id run either without worrying about it, but I've also blown up both versions so i disagree with people who try to convince me that you can't hurt a 4 bolt main, and i think i prefer the one piece rear main seal motors 2 or 4 bolt main they are balanced better but as i said I'd run any of them, although i won't power any 3/4 ton 2 or 4x4 with any 305's because I've destroyed 3 really good runners trying to pull around 3/4 ton trucks because i needed a motor and those were the deals available, and pretty much destroyed the bottom end on 3 h.o 305's with 601 and 416 casting heads i felt bad about that

Not sure if you let the air out of the tires or not but that helps to lower the vehicle. Gives a couple inches of clearance which can make the difference. Great video ✊🏽
@@dadatschool that’s true, I misspoke there but doesn’t it also depend on the density of the oil as well? Just because I had another engine that mixed coolant and oil and when I drained the pan the milk shake came first then the coolant which I why I said what I said here.
@@BoneyardRevivals No, density/viscosity won't make any difference, however, if an engine is run such that the oil pump picks up water and oil, it will combine them to turn them to milkshake color. My reply had to do with an engine that has sat for a time where the oil and water separate out or if there is not enough water for the pump to pick it up off the bottom of the pan. 👍
993 heads are great flowing heads. Both the original 993 heads and the Hecho en Mexico heads are good flowing smog heads. Goodwrench and Targetmaster used the mexican versions. This is normal to find on a crate engine
You gotta clean the heck out of all those coolant passages. It looks to me like somebody at some point mixed old school green and orange coolant together. I had a 98 I LOVED. Had a shop service the truck and even though I caught him before he put too much green coolant in, that truck had issues from that moment on. I flushed it over and over but I had to put a water pump on it every 10 to 15 thousand miles. It filled the system with a silty floury sludge. I got to where i could put a water pump and thermostat on in about an hour. Might not be your issue but that motor is from the "dexcool" era. Could be why the head gasket blew.
@@natelofties8533 When we pressure washed the block I pulled the drain plugs and sprayed through as many of the cooling passages as possible. And I understand to well about the dexcool era. I got a 98 Buick Regal and had a bunch of issues with that. What a nightmare. Definitely a face palm moment for GM.

ya mine came from factory already machine to take a roller set up , im not willing to spend a extra 2 grand to do what a great flat tappet can do also , the lifter pockets are a 1/4 inch deeper but doesnt effect push rod travel . crazy thing fellas in 1976 it cost 200 bucks for a rebuild master kit all new parts and a hard earned 65 bucks for machine work
Well, I can't hear the valve tick. Does it have a bit of an exhaust leak? (joking) The 350 workhorse, improved greatly by fuel injection, electronic ig, and the 4 speed.
I hope you're going to pull the rod and main caps to at least take a look? maybe check it with plastigauge - not a bad idea and would only take an hour or less and could save you hundreds plus time..

86 to 95 are tbi heads the 993 heads are also to that engine , someone has swapped intake for a carb ..if you plan on building that engine at the very least mag the block
@aintskairtolskol9520 I don’t think this engine was ever touched. There was zero evidence of anyone being inside of it since it was assembled in Mexico in 86.
