sometimes i get something come my way lol anyways i stopped by a local auto wreckers yard today looking for a sending unit(no luck there) but when i was walking out i seen a good looking FE...its edlebrocked out with C8xx-x cylinder heads i think there was an H at the end.. guy said he had it for 6 months now he kept it as coladeral and guy never showed up with the money so hes selling it for 600. i think he said it came out 68 f100, he said its a 390 never the less.. im going to go by there tomorrow and measure the stroke.. i have my fingers crossed for a 410 i know somewhere on here someone has the stroke in metric ill keep you posted.. im really thinking about buying this block and getting out that ol 360..
is this true...the higher the compression ratio shortens the blocks life expectancy and rebuild?
is that why 360 last so long?

 

The 360 lasts so long because it has no guts and can't rev high enough to cause any damage, with a stock 2bbl

The 390 lasts just as long if you take care of it, making sure the rocker shafts don't wear out and lose oil pressure as a result.

 

duly noted

 

Sounds like C8AE-H heads which are just nice standard heads unless they've been worked over a bit. What has been "Edelbrocked out" on the engine? I would try to haggle a bit if it's just a nice core engine with a performer intake on it.

 

I agree... Can't hurt.

 

block #'s usually dont mean too much except narrow it down to the years a 428 was made making it a "hopefully" its a 428. At least in my case a guy said he had a 428 c6ME block which turned out to be a 390 2U crank after taking off oil pan. Stroke can tell you if its a 428 crank but only if its a 4.13 bore is it a 428 otherwise its a 410 as I'm sure you know

 

welp she turned out to be a 390 i measured TDC to BDC and it came out short,
its still a nice block but not for that price ill see if i can haggle a bit

 

750cfm carb, performer intake, valve cover

 

Fordmanshane, I need to measure my stroke in my old ford to see if it's a 360 or 390, I was told it was rebuilt a 390, but we know how that goes. I know the stroke of a 360 is 3.50 and a 390 is 3.78, I have read to take a spark plug out and use a wooden dowel and bump the starter and measure from top to bottom of the dowel after it has been marked. Can you help me or walk me threw the best way to do this???? Thanks

 

welp what i did was i had an old osh ruler i had laying around, cut it down to side about 3/16...small enough to fit. took out the #1 spark plug then my buddy cranked her over a few times with the ol thumb trick. stick your thumb OVER the #1 cylinder spark plug hole. crank the engine until you feel pressure on your thumb. That's the compression stroke. TDC is at the top of this stroke. mark it and have your buddy rotate the crank carefully and once you have reached BDC mark it.
