Blown engine update/New Build w/pics For those of you who read my last thread https://ls1tech.com/forums/generatio...ken-crank.html
Once i got the heads off and realized the entire bottom end was toast i started rounding up parts and a new block and crank. Just got around to taking the bottom end down and seeing the extent of the damage. Here is what i found
It seems that a bearing spun then basically welded the rod to crank, the rods then broke in half and one shot out the side. There is deep scarring on the crank and so much debris that even the pistons and rods next to the cylinders that broke have marks all over them.
The new build is in progress now and should over all be a much nicer combination. Of course i went ahead and had the Dart Pro 1's ported with a nice 5 angle valve job which picked the flow up substantially. Just waiting on a few pieces to finish her up now, hopefully it will be going back in the car in a couple weeks.

The new setup will consist of Eagle H beams, JE 10.8:1 pistons, ported dart pro 1's, EPS cam .600 lift 230/234, Ati damper, ARP hardware etc. and will be tuned by Geoff at EPS. Here are a few pics

Oh yes, sorry i forgot to mention it also has a fast 92/92 setup on it. The heads were flowing 310(turbulent though) intake and 225 exhaust, after porting they now flow 328 intake and 267 exhaust. A buddy of mine in the Baton Rouge area is doing the head work, he does great work and has great prices too. If any of yall ever need any work done just hit me up and i can put you in contact with him.

Its a stalled auto, 3200 vig stall. It made 423whp before with 10.0:1 compression, its going to be around 10.9:1 now and heads flow better. Ill be happy with anything more than i had as long as it stays together lol. From what ive seen on other setups it should be around 440+ though.

Honestly i dont know, i bought the car as it was. The previous owner had all the mods/build done by Futral Motorsports so i would imagine they did but i do not know for sure. It was built in 09 and had close to 40k miles on it.
