junk 557 what now

well i just found out my 557 is toast it has a sand casting in the bore were water may have gotten in.the seat
pressure was to low causing the vale to float should have had longer valves and different springs .the balance
job was bad they swiss cheesed a new 4340 crank .the pistons are junk they milled them were the pins go
through .had 2 broken spring and some cracked keepers.the crank has 2 small longitudinal cracks on 3 and 6
rod jurnals .ring gaps were from 20 to 35. the crank is sprung 003. and i payed to have this motor
profesionaly built what a fricken joke.

anybody have a short block for sale.

is there anything you can salvage out of the motor?

Im sorry to hear that man

WOW.... sorry to hear that

Jake, have you spoken to Leach yet? It will be interesting to hear what they have to say this time, we will find you something, I seen a 466 somewhere on here for sale, supposedly new, but, you know all about new motors.

That sucks man!


There was a 528cu engine for sale

Im going over to pick the stuff up sat iwill see if i can post some pics. No harold i am never talking to him again
i wont bash anyone in public i will leave it at that.The heads are still good .the rockers stud gurdles pushrods
guess thats about it.I may put a 466 together with bluethunder heads i have a set of new pistons and rods
but those heads need some valves and springs .I have not figured out what to do yet.He said the crank may be
ok but they have so many holes in it and were they put the heavy metal he dont think they can balance it again.
Basicly he told me three things killed it valva float balance problem and the lack of priority oiling.

I read one of the other posts and he said it was a chevy engine builder...
Also said something about pistons smacking heads with some being in the whole and some out of the whole
warped block deck perhaps?

we had a block in my tech class that did the same thing and it had a badly warped deck caused a head gasket blow out right at the water jacket.

No thhis motor was in three blocks.It wasnt warped the pistons were rocking in the bore hitting the heads

the bore is not round or straight.

ah i sees.

i will keep an eye out for a shortblock if i find one ill let you know.

I'm not 100% sure I would use the crankshaft if it cracked.

Its been a on goin ordeal but they fixed everything at the end of last year and i put 18 i/8 mile pases
the seat pressure was 210 witch it has around a 810 lift cam trick flow ad says heads are good to 850
at that point they coil bind .it was a brand new 43040 crank what happened it broke a lifter at the last race
well after looking at things it had broken spring from valve float witch im sure is what broke the lifter .I was
told they did a valve job last time i ask why and was told just to make sure they were ok.The heads have about
70 1/8 mile passes on them .Its in a 4 link dragster witch would go hi 4.70s low 4.80s .
i paid for everything. every time i am frustrated to say the least.

A Chevy engine builder, unless he is an ALL brand builder and has been in this for a long time, will enevitably build it like a CHEVY; paying attention to what a CHEVY needs and likes. His mention of needing a "priority" oiling system shows that entirely.

All I can say is ... choose your builder wisely...!

The guy that did it first never said anything about oiling the guy who took it apart said to bush one side of the lifter bores and restrict the other side i think.I cchecked the lifters there is no way to put them in backwards
they have a oil hole on both sides above were the oil feeds. thanks guys


he actualy said he wouldnt put it back together without using a aftermarket block.

I hate to see anyone have these problems but if someone did me this way 3 times ,it would'nt bother me to Bash him in public.
The engine i'm building for a forum member was first assembled by a (supposedly pro engine shop in Columbus Oh). When he took it to them he specifically told them that he had problems w/rear cam bearing. They built the engine for him. He showed up at the Bash last year and the Cam broke into in the staging lanes. After taking intake off to inspect. He found that they had fixed the cam bearing by NOT INSTALLING BEARING IN BLOCK AT ALL As I was putting the engine back together for him . I found lots of screwups. The rod bearings had only .0015 clearanes.mains had .0018 The retainers were hitting the rockers. So know the builder and his work before investing your money.
