What started out as a simple crank swap has turned into something much more. Took the freshley built 355 apart (only 2,500 miles on 355 rebuild) to have the block clearenced for a 3.75 crank. Well I ended up selling my whole bottom end to a buddy of mine (brand new forged scat rotating assembly). I bought the callies compstar 383 package, callies 4 bolt mains, jessel shaft mount roller rockers, cloyes double roller, AI 215 tfs heads (waiting on) and I will be getting a larger cam (have not decided yet).

I got the block back and installed the bottom end. Put in the melling hv pump and welded the pick up tube. I am using clevite h series bearings for crank, rods and cam. I am alos using arp bolts and felpro gaskets for just about everything. I put my oil pan on (just my stocker) to button everything up just alittle bit ago. All that is left to do now is decide on a cam and put the top end together and I should be making some nice numbers. I also got a performabuilt level 3 trans and strange s60 to order and put in.

I have also thought about some spray and maybe even a sts kit for the car what do ya think. I have some extra money and I am looking at building this thing up big.

 

I think you should of thought about boost before you put it all together, a little spray never hurts.

 

uh oh, a HV pump and a stock oil pan?
you might want to search the forum reguarding this.

My sts turbo 383 (re)build is also underway. You'll be just fine using an sts kit if your compression ratio isnt too high.
Also, did you go with the Cloyes 9-3145 double roller?

 

I would go spray. Boost, your going to have to change lots of parts to get your compression down. Than a cam designed for it. Id stay NA and a 150shot.

 

+2 on the spray. get ahold of brett baur to spec you a cam

 

Hope the 1 and 2 rod clear the stock oil pan, usually have to take a hammer to it to make it clear. I would seriously rethink the hv oil pump, theres no need for it and it can cause problems.

 

Agreed on the HV pump on a stock pan. I'm using the Canton 7-quart pan with the Melling 10552 HV/P pump per my builders recommendation (also using H-series bearings).

I also suggest upgrading to the Melling Select line of oil pumps. They have a much more robust casting than their 155 counterparts.

 

Let me clear up some confusion. The bottom end has been built for the sts turbo. I have JE extreme duty pistons and hellfire rings. I also need to be more clearer on the oil pan. I am using the stock pan for now to keep dust and debris out of the engine. I plan on using a stefs pan but have not got it yet.

 

Yes

 

Just saw that STS is working on a twin turbo set up for 93-02 f-bodys. Here are the links.

If this goes through it will be on my car guaranteed.

 

I will be 100% going with the STS system. I originally started the rebuild for the vortech supercharger kit. I think the turbo system will be better and if I can do twin turbo it will be even better. I am also planning on nitrous to either help spool the turbos or a fogger type system if I need it.

 

Money must not be an issue here at all considering the route your going. However to accuratelly give you other suggestions it would be helpfull if you would provide the Static Compression Ratio, Dynamic Compression Ratio, CC of the heads and CC(dish or dome) of the piston you are going with. If AI is doing your heads I'd let them know exactly what you are doing in regards to the whole set up and they can have a custom grind for you that will work for your application. I'll tell you right now that a shelf grind on that sort of set up is not going to get as much out of it as a custom grind from AI or BRE.

 

AI is doing the heads and more than likely the cam and intake as well. The pistons are dome JE extreme duty. I should be running around 9.2:1. and I am not getting into all the other technical terms.

 

That's just a custom deal, not a kit.

 

go to lt1boost.net and have him build you a turbo kit. Simple as that
or hop on the foresale section, theres several people selling turbo kits
