Hey all I just bought my first truck it’s a 87 ford bronco full size. She’s got a straight six and a 4 spd manual. When replacing my head gasket I discovered a hairline crack about 5 inches long on my block. I need to get a new engine and I am having a lot of trouble with finding some any suggestions on which one I should go for preferably would stick with the L6

Not alot of Broncos have the 300 I6, its almost a cool cult classic kinda of deal to see one that does. If I were you, I would put in a new 300 I6. I know the v8 Broncos like the upper RPMs and go down the highway better but I would spend the money.

My Idea would be to start with a craigslist engine, find a trusted machine shop and work with them 1 on 1, roller rockers, EFI friendly roller cam, high flow (regular pressure) oil pump. but still keep the compression stock so the factory EEC can run the engine with out issue.

Just an idea of what I would do if I had the opportunity.

it prob was frozen, the blocks are pretty rugged otherwise... you could totally get a junkyard engine if you have them in your area at the local jy.. the blocks are most always salvageable, if not in generally running order. people junk those rigs because the fuel pump died here in seattle. lot's of em. i'd prob drop the oil pan before pulling it and see if it's carboned/gunked up. but finding a 4.9 block ain't hard. they made shitloads of em. they sometimes end up in the jy because of the phenolic (plastic/fibre) timing gear. if you drop an oil pan and you see bits of gear, find another one. if you find a good one, replace that phenoolic gear with a alum/steel combo. it will last way longer than any of the v8's will.

I love those 300 I6 engines, especially with a manual trans. I had one in a 81 E-150 van that was in my family for 37 years, never had a problem with it. They are available in the junk yards near me regularly, I think they were in trucks until 1993ish. I don’t know when they went from carb to EFI, but if yours is carb I’d try to find one with EFI if yours is carbed.

Not sure where your at. But look for a F150 with the I6. That should be the same engine. Plus lots more of the F150's had them then Bronco's. Wish I could have found one with a I6. Know most don't like them, but man they just keep going and going.

Spend the extra money and get a genuine Ford remanufactured I6 and have the dealership install it. Also, you get a 3 year warranty and unlimited miles.
