88 L98 got blowed up
 

It's official. The motor has a hairline crack in the back of the crankshaft. Now I need to decide if I will sell it as is or try to get a new motor. I'm not fixing the stock L98. :cry:

for years now ive been contemplating gettin a 355 or 383 from summit for my 88

I believe they sell 383 kits at summit. I guess I could have my current motor rebuilt with the 383 crank/internals/pistons etc.

And to think it passed tech :lol:

Glad you went and got it checked out before you ran it, that could've been worse. I'd look into a basic crate motor, there's no real ready replacements in the classifieds that I saw.

Yea the mechanic said $4,300 for a Jasper replacement. I said no thanks...

Say no to Jasper for performance apps in general!

Now the question is:

- keep car/build motor (nothing Jasper)

- sell car

low mileage GTA.... keep car

Sucks man, gen II/gen III swap da bitch!

1. Purchase LS1
2. Install into said car
3. Beat BigAl to the LS1 punch
4. ?????
5. Profit

Haha. I'm thinking LS1/LM7 but I need to check the old 401k first...

jasper really that bad? i know my truck is gonna need a motor in the near future.

I cannot say firsthand but I have heard stories from reputable sources about one-hole bore jobs and mismatched heads.

hm. guess a replacement gm truck motor is in order then!

I would keep it for sure. For half that price you can grab a GM Vortec long block and all you would have to do is grab a Vortec TPI base and maybe a cam and spring kit if you wanted a bit more power.

Highway robbery...

Buy a summit block machined to a 383 for like $600. Check out ohio crankshaft's website. You can build a reliable factory roller short block very cheap.

You have a few sponsors here that can help you. Screw Jasper, Summit etc...if you're going to do it, do it right.

Yea that would be my plan because if I build it back up I'd like to do it the right way once and not have to touch it or worry about it again. I'd love to go 383 and get the whole motor tanked and rebuilt. I just need to secure the funds first. Luckily the car is in my driveway and not going anywhere. I'm smelling a build thread coming...

It also sounds like the engine did not go out it a 100% blaze of glory so you probably have some stuff you can re-use.

Yea like my TPI. Yay :rolleyes:

Im glad you didnt end up running i knew that balancer wasnt looking healthy, good luck with your build if u decide on keeping the car

Why would you spend more money on machine work on your block instead of getting a 4 bolt main pre-machined block that just needs a final hone? Not to mention I am unaware when GM went from hydraulic to roller setups (I know its around the year of your motor).

Summit block is a heck of a deal, ohio crank has some good stuff that the big-name companies can't beat price wise. You can pick up a set of vortec heads for next to nothing and rebuild them with beehive springs and pump out 400 horses. Won't get much cheaper then that. Under 3 grand can build a long block with mainly new parts.

SDPC has a 383 bare block on sale

Ok so that long block plus this base

Would put me out around $2500. I'm assuming I could use my stock ignition with that long block? Then headers/y-pipe and I'd have to look into cams/springs. So without installation I'm guessing around $3000 for that part of it.
