Re: so i went and looked at this today

cleaned up the engine bay harness today of extra unwanted wires / parts .

stream lined it to coolant/oil psi sensors . tach/12volt to hei . carb 12volt kickup power.

got few question tho on the carb parts . 1988 7000 366 gas 5 speed .

pic 1 = is this the 12volt high idle or what is the correct name ? ? ?

pic 2 = vac port item pushes to the linkage but dosnt touch anything . what does it do ?

pic 3 = seems to restrict vac to secondary diaphragm . 12volt opens flow . can I bypass it or just leave it alone ?

pic 4 = looks like a tiny vent filter unit thingy . . whats its name and function ?

pic 5 = the whole carb for refrence.

Re: so i went and looked at this today

Not sure, most likely a secondary lockout while the choke is on during warmup.

Re: so i went and looked at this today

Send your original motor to the machine shop for re-bore and have the heads reworked. You will then have a new motor that is dependable.

Re: so i went and looked at this today

I don't think its even going to take that . . .

pulled a valve cover and you can basicly eat off the inside of it . my buddy bore scoped the plug holes and all but 1 super clean . 1 has tinyest bit of powdered surface rust in 1 spot.

Friday its hanging on a engine stand and tearin the heads off . were going to find out the rest of the story as paul Harvey would say .

Re: so i went and looked at this today

Amazon has a set of 8 pistons .030 or .060 oversize for $265.00. If you have a good block you can overhaul these fairly reasonable. Even if your bores are good, a new set of pistons will go a long way given you have new ring lands and you don't have to clean up the old pistons.

Re: so i went and looked at this today

I just had a 427 rebuilt -the engine kit was about $1050.00 included pistons,,rings,bearings,timing set,oil pump,cam and lifters and gaskets.Machine work-bore .030,polish crankshaft,plane heads,valve job,and assembly was about $1075.00 . So about $2200.00 total this should give you some comparison for what a total rebuild will be.

Re: so i went and looked at this today

well the truth has reviled its self on the original motor .

COOKED TO A CRISP AND BEYOND

heads have pushed out guides chipped valves 1 has huge 3/4" long crack going from valve seat up to intake surface .

all the pistions all have aluminum melted off them and severe frozen rusted on rings.

1 head even started to pop / lift up when undoing the head bolts in reverse sequence of pattern .

she is beyond the put a stick in it with a white flag . she gave up the fight well before this guy owned it that's for sure.

Re: so i went and looked at this today

Can you bore the block and use the heads off the used motor? The seller might give you a real deal on the used motor rather than pay freight back to his location.

Re: so i went and looked at this today

the used engine - the amount of rust in the cylinder and on the wall we can see with a bore scope its going to 98% change be a junk head and at least rebuild the head .

the local machine shop said I drop off all the parts and he does up a motor turn key broke in on his stand and tested with warrenty over 3k bucks. and its starting the race season rush so who knows when he could do it .

I am digging deep in to this pig and getting closer to time to cut my losses ( small amount ) and sell the dump box off it and make my own toy or flatbed hauler out of it .

I also could do a cummins 8.1 diesel / allison auto combo but that's going to cost me 4-5k range for a good take out . then fab up mounts and few other items. way more than what I wana do on a chance someone would buy it . . .

if I made a toy out of it it would be a 4x4 swap and some sort of late model motor swap in / or 6vxx series diesel engine.

I just don't know right now. . . . . I don't wana make it 100% and then loose my arss on sale . . . . if I have to break even now is the time for the part out and make a toy .

Re: so i went and looked at this today

about 98% of all these reman engines say NOT for water cooled air compressor application . . . .

I have this application engine . and the ones that do require a specific block / heads casting no's or no credit on core . and the used -junk engine I am not sure whats going to happen to it yet. and I prob cant even use it as a core just my luck .

Re: so i went and looked at this today

I'm sure if you shop around you can fine a machine shop that would bore your block .030 or .060 oversize for $400.00 to 600.00. Simple engines to rebuild, doubt that rust would have ruined cast iron head if they have not been overheated. I would pull heads on used engine and take a look. I didn't realize air compressor engines were different. Overhaul kits are cheap, 500 to 700 dollars. Transplanting anything else into it will be much more work and cost.
