my Subaru will beat with a Buick heart!

^ the cam i had is a zero overlap cam. it ran rough because of the compression bleed off from the intake valve closing late.

That thing is sick.

herd a bit of rattle on decel ..

 

coupple hours and swapped it out.

 

last time it tore the center right out in 2006 at the drag strip.

good catch. looks like that could have gotten ugly.

meh last time it broke completely just had to tow it home

You know this wouldn't happen with a 6MT:rolleyes:

Looks like it would need some reinforcement.

that wont but everything else would be broken

just read all 1300+ posts. Frank- thats great work man. I had a 1998 Pontiac Grandprix SE that had the 3100 in it back in highschool. One summer i saved up enough to grab an entire front subframe, eng trans, etc from a 2000 GTP and swapped it over, modded before installed. That car was an absolute blast, and eventually became the oh so deep money pit. I eventually blew the motor after putting some nitrous on it at the strip. Miss that thing. congrats.

why thank you .. but this has little in common with a gtp.

Yeah I realize that. Still an awesome job and very unique.

so the crank shaft broke. ( it was a welded and re machined on #6 rod)

and it broke between 5 and 6 rods. and it was still running !

 

took it apart and that piston is fine just gotta change the rod. and i will likely change the block also, the walls have some scores and i don't want to take a chance that the block mains are fractured somewhere.

 

anyways i figure the crank broke because of the welding and them not leaving nice fillets that cause stress risers that make the the crank weak . those tiny fillets are the most important part of the crank!

wow that looks harsh

Why was the crank welded, offset grind for more stroke?

Wow, that looks nasty.

new stuff gone to machine shop for turning and boring.

You can't just pull another lump out of the junkyard for a few hundred bones?

Well mostly that's what I am doing. But it's a cleaned up motor with my forged Pistons and mls head gaskets , it's not expensive to get block bored about 120$ and the crank w bearings is 180$

 

It's not bad to have a rebuilt short block for under 500$

tru dat

Go ahead, keep rubbing it in...

 

Looking forward to the outcome.
