FE Technical Forum / Re: HEAD BOLTS RESTRICTING OIL TO HEADS
« on: October 27, 2014, 04:22:39 PM »
Heads are edelbrock performer RPM. The restriction is only when the head bolt is in. I pumped oil with the drill and oil flowed freely out of the head bolt hole and the oiling hole in the chamfer for the rocker stand. The PRW rocker stand is drilled larger than the stud that holds it the issue is down at the junction of the head and block with the oil trying to get around the head bolt to the short galley that leads to the rocker stand. As soon as you start to thread the head bolt in is when the oil to the rocker stand starts to become compromised and only gets worse the tighter the bolt. Initially when I spun the pump there was no oil at all coming out of the rocker stand orifice, only after the head bolt was removed did the oil flow freely from both holes and like I said as soon as the head bolt was back in only a thread or two the flow started to slow. It still oozed out of the head bolt hole with the bolt loose but the tighter the bolt the worse the flow out of the rocker stand orifice. Barry_r has it right the head bolt will have to be skinnied up a few thou.

Thanks a bunch guys for the input. The oil pressure with the drill was up to just about 80 lbs. By the time I stopped the drill and looked at the gauge on the dash it was about 75 and falling. When I mentioned that the adjusters on the rockers weren't centered it was left to right front to back just all over. To me it just looks like $#@^y construction on PRW's part. As far as pre-oiling I was told to just pull the coil wire crank till you see some pressure and let her rip.

Hey all, I'm having trouble with my 447 fe stroker. Lost a pushrod after only about five hours of run time. I think it was a combination of wrong pushrod length and not enough oil getting to rockers. Rockers were PRW Pq. Twelve of the sixteen got chewed on by the cups. The lash adjusters are not even centered in the rockers themselves. You can see it with the naked eye. I'm switching to T&D street set up and ball ball pushrods. The oil issue seems to be only on the passenger side. After removing the rocker assembly on both sides and the distributor I put a drill to the oil pump. Good flow on the drivers side none on the passenger side. I removed the head bolt that corresponds to the oil passage for the rocker stand and lo and behold good flow from both the head bolt hole and rocker stand stud hole, tightened the head bolt back to just 60 ft/lbs and the flow dropped off significantly, less than the drivers side. I am going to talk this over with my engine builder to see what the problem may be. Gasket interference? Hunk of $#@! in the oil passage? Oh yeah, one more question, am I in for a blown head gasket down the road since I took out and put back in one head bolt?

I think that the turning the engine over without the coil wire primes the oil system with out removing the dizzy. At least that is what Mr. Parham suggested. My main concern was the amount of time that it will sit. the drizzle idea was just that a little oil is better than none up in the rocker rollers, valve stems etc. I'm just a bit paranoid of something going bad, just the way I am.

FE Technical Forum / Stroker first start up

Hey all, thanks to the crappy winter we've been having here in the north east delivery of my Unique Cobra will be delayed way longer than anticipated. When I finally do get the car there will be a month or two of work to get it on the road. Here is my question; since the engine was built and the cam run in back in late November and probably only has an hour or two on it, when I get the car I was thinking about draining about three or four quarts of oil and over the time it takes to finish the car I want to drizzle oil, about a quart a week or so back into the engine via the roller rocker tips and down the outside of the push rods so the oil can soak the lifters and bores from oil running down the push rods. When I'm ready to fire it up It'll be the standard crank the engine with the coil wire off till there is pressure then put the wire back on and pray. By the way it is a Southern automotive 447 stroker. The engine will probably be sitting till late april or early may. Any suggestions would be appreciated. I will also be in touch with Bill Parham but I would like as many opinions as I can get, RPM's first drive, etc. Ive been told by some not to take it too easy on it when I get it on the road because you should have strong cylinder pressures to seat the rings correctly but not beat the you know what out of it either.

FE Technical Forum / oil filtration
« on: December 25, 2013, 09:09:06 PM »
Hello to all, first post so bear with me. I will be taking delivery of my brandy new Unique Cobra in about two or three weeks from now. The engine is a 447 stroker, solid lifter, 10.2:1 750DP from Southern Automotive. I will be installing an Accusump 2 quart for basically pre oiling only. Bill Parham suggests a motorcraft FL1HP filter. I have been eyeballing the canton CM spin on filter, lots more moola but better filtration. However it does not have bypass or flow back capabilities. So anyone reading this and has an opinion let'er rip.
