it is an external pickup.

i was trying to think of anything we could have done to it but it has only sat on the engine stand. we wrapped up the carbs so nothing would fall in.
we even took off the blower before we turned it over, it wouldnt fit into the car with the blower on .so we have to set it in then put the blower back on. i would have thought if we did drop anything into the carb the blower would have caught it and it would not have made it into the motor.
i cant see how anything got into it here. we taped all the holes shut and they still are.
when we dropped it off the shop was full of blower motors,so it looked like he was used to it. they were all chevy motors with a couple fords though.

i will let you all know how it turns out.its going back today .

Hard to believe the engine builders wern;t turning the engine over all the time checking deck heights vavle to piston clearence, ect. i would think a 500ci blower engine would have atleast a single external pick up. I would have the whole engine looked over before giving anyone any $$$


I can't believe that they wouldn't degree the cam in a 500" build. That would garantee rotation of the engine.

Did you check and make sure they took the piston stop out if they did degree the cam

we were just looking into the spark plug hole with a light shining in through the valve when it opens i can see half the piston and there was nothing i could see. i thought something may have fell into the exhaust valve and onto the piston. we even turned the motor on its side so if there was anything there on it it should slide over to the side i could see.
the guy that built it says it spun when it left so if he takes it apart and there was nothing he did we would have to pay him. i dont blame him for that but if it was something we dropped in and he pulled the heads to get it the gaskets are $130 for the heads plus labor so i just wanted to be sure there wasnt something dropped in it.

If you have him do it be there when he disassembles it because if you aren't the next phone call will be looking for money because it wasn't his fault .

There's a reason I put my own stuff together...After some of the stuff I've seen I wish I could do all the machine work but thats just not realistic...

Make sure the flex plate bolts to crank are not to long.

Don't ask me how I know....

Ihave to assume you didn't turn the motor over on the stand,and I can't believe the guy who builds race engines would give you the motor that way! You mentioned bellhousing,if you put the flywheel on maybe the bolts are hitting the block, if not I would pull the pan down and see what's going on!

In my last post I said I can't believe an engine builder would give you the motor that wouldn't turn over. Their are engine builders who rip people off and I know few on long island who since moved out of state because nobody would deal with them anymore. That's why I said take the pan down and see for yourself and then take it back so he can't BS you! Good luck.

there are no flywheel bolts in it yet , that was my first thought too but its not bolted on yet.
we called and he said bring it over tomorrow morning and he will pull it apart while we are there.
i didnt want to take anything off myself because he may say we messed with it.

A few weeks ago my son completed his stroker motor which while building he routinely turned a complete 360. Everything was fine until he tested the oil pressure using a drill. Something was not quite right with the oil pressure but even more disturbing was afterwards the motor would lock up at about 180 degrees each way. Turns out an oil galley plug blew out and fell on the crank timing sprocket. The plug would lock on the timing chain on each side. Next time he is going to tap the holes and use threaded plugs. Since he was worried about valve interference he was relieved to discover the plug caused his problem. Good Luck!

Call him up, tell him what happened.
When he's done "explaining", tell him he has 24 hours to come over and pick it up, take it back to his shop, R&R it with new oil, gaskets, etc. and deliver it back again.

Unless, of course he wants to pay you $75. an hour to do his work for him?

If he refuses I'd like to know about it.
Wayyy too many "famous name shops" have screwed up like this (including for magazine projects) and they were very careful not to let it get out.

I'd reserve all judgement until the problem is found.Like what has been said,be there as it is being dis-assembled.Don't be surprised if some thing is found on top of a piston.Do you have or have access to a borescope?Do you know which cylinder is near the top of it's stroke when it locks?You can determine this by turning the engine until it stops,back it up and
put your finger over the plug hole to feel pressure. Also if it's a blower motor,check your pully bolts on the front of the crank and make sure one is not interfearing on the timing cover.Check the same on the blower.

the builder said he has something he can look into it with. i am not going to badmouth anyone yet. there could still be something dropped in on the piston.
anyway everyone screws up once in a while.i will see how it goes tomorrow morning. i will be really suprised if there is a nut or washer that fell inside it from me, i was really careful and i cant see anything on the piston. we even used a small magnet to try to find something.

It may have been fitted with either a non stroker or insufficiently cleareanced windage tray and it may only touch/scrape on one pair of rods....I'm sure he would have spun it around before putting the pan on it. Just tightening the oil pan bolts can be enough to make contact by compressing the gaskets.

Its how they handle the problem that will tell alot about them. It could be a number of minor things.
