ls1 build thoughts
The block looks good still had cross hatches in the bore no ring ridge and no scratches. The scary the crank looks like someone let a beaver loose in the bottom end and it thought that rod journal 6 was a branch or something. So needless to say the crank is not good. The kicker is that the engine was assembled and had a extra crank that was given with the motor but that crank looked the same, and on the same rod journal. Me thinking okay they must have replaced the crank already. That was not the case so much for assuming lol. I have talked to a couple machine shops and they all have said that it can be fixed but in my mind thinking to have to speed that money to fix that old crank why not just put that money toward a stroke kit and make my ls1 a 383?
The place I am at now is what lower rotating assembly for the money is the best?
What Compression ratio should I shoot for and heads and cams to use?
And what supporting mods would I need? Like fuel system and anything else.
Thanks in advance
And I had thought about doing a 6.0 in the first place but unsure maybe ill end up there who knows im not apposed to it even with the added weight. I just know I dont want to deal with forced induction due to my lack of knowledge as of this point.
Whats a machined as in checked out every thing is good and has a fresh hone ls1 with a stock bore go for grated its a 98 block its worth something right? If I decided to go lq4 route whats the price there??? I know im looking at at least $2500 for a lower end as sits if not more probably a lot more lol.
You can get a full rotating assembly with bearings balanced from TSP. K1 Crank, Compstar Rods, and Wiseco Pistons/Rings would be my choice. It's about $2400 or so for a 383. You can do 475 with a 383 and have a pretty streetable motor that can take some abuse.
I'd build it with a nitrous cam in mind and run it on the sauce. 250-300 shot and make good use of the limited bore and forged components.
Then you can go with some TFS As-Cast heads to keep it budget friendly.
HCI2000SS How much was the that and what all did you get? What ball park power are you putting down?
I thinking I am going to run 243 heads and just have them worked over cause like ive said doesn't need to be a rocket ship I just want to be able to drive the car alot and have fun with it.

I sold my my LS1 block for $400
And from here? http://www.thompsonmotorsports.net/i...e7km58japae744
Also that lower end doesn't give any specs. You got the one thats not forged correct?
I highly recommend calling TMS. They will get you in the right direction. They had the best prices I could find at the time as well
