I ordered a 400hp ford 390 from MOTOR WORKS in Spokane Washington. I paid $2200.00 they say it was dynode but when I received it the distributor would not fit in the manifold? Manifold was not centered. I did a compression test 90 was high 75 was low intake vacuum was 10 they say it is bored 80 over with a elgin E965P cam It runs like shit any help would be appreciated
send it back.........................
First of all, it's a Ford. It's to be expected . . .
Sorry . . . couldn't resist . . .
If compression is 75 - 90 psi, something is badly hosed. Bitch loudly and/or send it back.
and if they give ya any crap, I'd report them to the BBB also...joe
If the company doesn't want to do anything, or if you can't irrefutably prove fraud, not much you can do except a civil suit. This would be very costly, probably more than you spent on the motor. Best thing to do is find a reputable local company and have them check out the motor and see if the machining is done properly. Other than that, live and learn is pretty good advice. I will only use a machinist that I know and trust.
Go to Evergreen machine shop. I had a engine reworked by they a few years ago. They do great work and fast also. They may be able to look at the engine for you to see if something is wrong with it.
i know this is kinda off the subject. I have a truck that has a 390. After screwing around with having my heads done , It has kinda high compression. Is a range of 187 to 195 ish psi acceptable variance. The truck has an RV cam, and is bored .030, with a weiand intake and a 625 carter afb comp, and electronic ignition. Oh also it has Headers and roughly 2.5 inch dual exhaust. Roughly speaking, what kinda horsepower does this thing have? I have a dana 70 rear end with 3.73 gears and really rapping the engine out i can do about 105 mph, my tach sorta functions it seems the engine gets up around 5500 rpm. Really just curious of what kinda HP this thing may have.
PS i would think any reputable machine shop would do something to fix those problems. i forgot to mention, if the milled the crap outta the heads, you may have intake manifold problems if they didn't mill the intake manifold at the same time. Hmm i wonder if one head were milled more then the other, if it would create alignment issues on that intake, for the distributor. It could definately create sealing problems on the intake i would think. This big block ford book i have shows proportional milling when the heads are milled down, the intake is milled too.
