Are you going boosterless?

Got the cam in the mail today so finally have all engine parts. Pics of the shortblock assembled. Rest of the engine should be done shortly...

True that.

[CLM21]

Your engine cost more than my entire car + swap. Should be freaking awesome when done!

Haha. Well I can take the engine to the grave with me even if I decide to ditch the platform.

Got a few more parts in. Billet fuel rails and the heads. Should be getting the cam in later this week and then I can finally finish building the engine.

[CLM21]

Got the fast intake manifold in, along with oil pump, lifters, timing chain, gaskets, rocker arms, trunions, covers and whatnot. Heads will be coming in tuesday, and the cam should also be coming in next week. So next week, assembly will start on top end of the engine.





Also got all the brakes done yesterday. Mmmm wilwood. Should be getting the MC in on Monday so I can slap that in and start making the custom lines for the abs delete.

Got a bunch of engine parts in this morning. Pretty excited... Ill get pics up in a bit.

[CLM21]

Haha. Well Ive got some sticky 285s out back, so hopefully itll be drivable.

Dont really have a goal, just wanted to build a mean engine. I'm assuming the whp to be somewhere in the mid 500s hopefully.

Ought to be a little bit of a handful! And a heck of a lot of fun!

My stock LS1 will smoke 2nd easy with 255s in my truck, I can't picture it with my 225s in the 30:puppy:

What kind of WHP numbers are you shooting for? Looks like a good pile of parts!

Can't wait to get this thing completely put together.

Well, I was able to get some brake hardline at napa today, and ordered some fittings online. Was also able to find a 17/17mm MC from a VW rabbit, which should be getting here one Friday hopefully. So I should be getting the entire brake system done this week. I guess Ill take pictures in case anyone is wondering how I did the abs delete... I guess its not documented very well?

[CLM21]

If napa will make me some pre-flared with fittings that would be awesome... and theyre all gonna be custom lengths/bends.
