My Rampage... Cruiser/Drag Week Car

[MR P-BODY]

Well its ready to go to the dyno...I'll have to call tomorrow and see if their schedule
and mine can come together this coming week ... I'd like to drop it off Tuesday and
run on Wednesday

[MR P-BODY]

I ran it on the dyno but had problems.. it lost 100 ftlbs of torque in 3 seconds on
the second short pull.... ran a first short pull to 4500 rpm and it made 463 hp
468 ftlbs torque and then it started eating itself up on the next pull, it was down
the 100# so I pulled the filter and seen metallic in the filter.. so I pulled the pan
and 4 rod caps and a main.... they looked fine other than some of the partials
that got embedded but really nothing... I told them to pull it off the dyno and
I'd pick it up to take home... well I picked it up today and torn it down... seen
scratches in 2 of the bores but that was it... cam bearing, rod and main bearings
were fine(some embedded partials again)... I even had one of the engine builders
stop by my place to take a look .. he was stumped also... we have no idea where
this alum is coming from.... I cleaned that block 3 times before I assembled it...
all I can do is hone the cyl and CLEAN it again and start over...... I have no clue

Hope you get it figured out. The last 455 I built ended up getting torn down, everything honed again, and put back together. It got something stuck in the ring lands that started scratching a couple cylinders. No idea where it came from, lucky thing I found the scratches in the cylinders.

Is it the thrust bearing by chance? Only other thing that crosses my mind is cam bearings.

Did you have a hole go away on you? Did you get the dyno sheets, complete with egts?

I'll throw away any political correctness here and say, as we used to before all the harassment training, this car is "tits."

I like everything about it.

Run it at Bonneville. There are so many soft records in modified pickup that you're bound to get a couple of records.

no not the thrust bearing... it looks like new

No I didnt bother with the dyno sheet on the 2 partial pulls but it should make 600+hp
and about 550 tq based on what was seen on the short pull.... all I really want is 550 hp
so I think I have that covered
thank on the car.... never gave it any thought of running Bonneville.... but would be cool
to have a record

Bummer you can't convert a FWD to a RWD and fit in the mmp categories.

I dropped off another block today to have decked... everything on
it checked out good just needs to be decked and I'll put the same
parts on this block and have the original block bored to fit a larger
set of pistons... should be ready for pick up on Tuesday ... have
to clearance the bottom of the cyl for the stroker... just a minor
bit of grinding
