Motor is hurt, but I'm impressed...

[SAR2K]

Well last outing at the track my car steadily droped trap speed all day while the air got better. Total of 3 MPH. Well I did a compression test today to see which cylinders are letting go since the stock bottomend has 90,000 miles on it.
Well I found one of the weirdest things to date of any motor I've looked at. The spark plug in the #6 cylinder took a crap... one hell of a crap! The center electrode separated from the body of the plug dropping the ceramic and metal into the cylinder! :eek: Needless to say the compression was down for that cylinder, LOL.
As an added bonus the #3 cylinder has coolant in it... most likely the head gasket.
I actually drove the car to New Orleans this week (156 miles round trip) not knowing what was going on, just thinking it was a little worn out, LOL! Gotta love the LT1.
Hell after finding all this today, I toped off the radiator, replaced the bad plug and drove the car home from the shop... try that with an equally hurt LS1. :2guns:
Time for a rebuild... just need $$$ and decide on a 355 or 383... cranks are damn near the same price.

The cost negates the gains in hp over a 383. Not to mention the reduced block integrity.

yeah, most assholes that build 396s build them just to say they've got a 396 :jerkit: :D

Yep and cost is an issue here. Now that I'm not working in a refinery anymore I have to actually watch what I spend. :help:
I defineately want a forged crank since I spin the piss out of my motor. I looked around on e-bay last night and found quite a few affordable 4130 forged Eagle cranks. No price difference between 3.48 & 3.75 stroke. If I'm going to spend X amount of dollars I might as well get more cubes for the buck.
I've heard both good and bad stuff about Eagle products, but from what I see it's almost like the Ford-Chevy deal... just a matter of personal preference.
I'd love to have a Callies crank given the RPM I turn, but at that cost I'd be parked till late this year. Both 95Formula and I have been spinning the stock crankshafts to 7,000 without issues, so a good forged crank should be a good bet for longevity.

Andy, on the 396 LT1 deal... I've really only seen one actualy run it's ass off. There is a guy south of here (guy litterally lives in the swamp) running one in a 69 Camaro... it's BRUTAL! Last outing at the track he had to get off of it at the 1,000' mark for whatever reason and still went 9.4 @ over 140... all motor :eek: He's the guy that built 95Formula's tranny... very cool and knows his stuff. He's about to put a Gen 6 DFI on the car... full pass with that and that LT1 will be in the 8's!

Shoot me a mail I have a bunch of links for gooD stuff. CAT ia anouther good option and the word is COLA is the same as Eagle now ;)

[1FSTSS]

if it makes you feel better i dropped a rod through my oil pan over the weekend. so im doin a forged bottom end too. what is a good company to go with??

[SS MPSTR]

I found a good deal on a Scat forged crank, Scat h-beams and JE pistons.

[transamtom]

Sorry to hear your engine went,good luck with the stroker build up.

no shit, the minimal gain over the 383 is easily made up with a custom grind cam and the right head combo. I choked when I priced the Callies forged crank at $1,500.00 compared to a forged 383 for 1/3 the price.

ARE has made some significant changes over the last little while.

I'd consider talking to Nick over there.

[T/A lt1]

Hey Steve I bought a GM steel crank from a ZZ4 engine. IT is a forged steel crank and has a one piece rear main. I was going to use it but found an awesome deal on a complete 4-bolt main LT1 with 8kmiles on it!:cool: and I bought it instead and i will just be installing my heads/cam setup on it. So I paid $200 for it and it's fresh and ready to put in a LT1. I am asking $200 and we could meet up at SCD if you want it otherwise I am just going to keep it for later ;) LMK if your interested. Later Clint

[SAR2K]

Thanks for all the leads on parts guys! Clint I've decided to go the 383 route since I can now get all the stuff through TR real cheap and there is no difference in price between 3.48 & 3.75
I'll pass on the info to Tim H about that ZZ4 crank, I'm pretty sure he's looking for one.
Now I just need to find one more LT4 head to make a set, LOL.

Not bad man, your car was always real strong, should be a beast with the new motor esp since your with Thunder now.

If you haven't gotten the crankshaft yet, I'd reccomend 4340 steel, as it is a more suitable material for this application.

Andy it looks like I'll be running an experimental T-6B aluminum forgeing. We'll see.

wow, that's cool. I think the bat I used in T-ball when I was 7 was made of that! :)
