I have built engines in the past Fords and Mopars. This is my first GM and stroker engine. I need to keep all the smog controls on the car. I have been looking at a lot of forums and doing as much research as I can. I will be buying the parts starting in February and should have everything by August to install the engine. The car is a daily driver I don't believe is having something and not use it. I'm wanting to build a beast and still be reliable. The idle roughness is not a concern of mine. The car will see heavy street use by that I mean my right foot! I will be spraying it latter so I have chosen a bottom end that should hold up. Below are some of the parts I'm looking at getting. The right cam is my only problem. The clearance will not be a problem with the block and rods I'm going to be using.

Just wondering, but why are you thinking about keeping it tbi? You could very cheaply carb it and end up being a lot less into it in the long run. Think about tuning too...
although that setup looks badass.

I have to keep the type of induction the car cam with. It has to be TPI or TBI because NC has now started enforcing the emissions on all cars. I asked the mechanic I take my car to and he said if I change it to a carb it will not pass inspection. I have to keep it to keep to what came on the car.

MotorMouth

That setup is EFI but still allows me to use the throttle body and ECM the car came with. That's why I have chosen it all I will be doing is adding the throttle body assembly from a 454 to get more air flow. The intake is a single plane and doesn't restrict like the stock unit does.

The ECM should be the first part of that car you should change, at least look into EBL, or you could try to go with one of the EFI connection conversions.

I've been reading up on 350 as much as I can. I've only built Ford and Mopar engines in the past. This is my first Chevy and Stroker engine I would appreciate if you guy's could help me out here. I need to make sure these parts are compatible. I'm trying to keep my budget around $5000 for this stage in the build.

I have to keep the car smog legal so going to a carb and ditching the emissions equipment is not practical.

I have been doing more research on the TBI system above it would work but limit the engine in the output it's capable of.

This engine will be sprayed with nitrous

I know this is a very aggressive cam for a street car but I will be using a 200 shot Nitrous system.

That's it for stage 1.
-----------------------------

Stage 2 will be the DynoDon's coated headers w/airtubes.

Stage 3 will be the TPiS Stand-Alone Mini-Ram system. I'm open for other suggestions on this because I'm going from a TBI to TPI. I'm pulling the motor out next year and will be replacing the wiring harness anyway.

I know this is a very aggressive cam for a street car but I will be using a 200 shot Nitrous system.

The compression should be around 9.5:1 to 10.5:1 and I will be using pump gas. From what I have been reading this should be OK setup and good for 550+ HP and 500+ ft-lb/t. I'm going to be getting the Stage 1 parts this weekend.

IIRC i have a set of wiesco pistons that turns a 350 into a 383. They would be in my garage back home. Send me a PM.

The crank would change the displacement from a 350 to a 383, not the pistons by themselves.

Some of my parts are coming in this week. It's going to be spring 2011 before I can put the engine in the car. My question is what would I need to do to protect the engine if I build it as I get the new parts until then? I have ordered engine bags to help. Would it be a problem to go ahead and assemble it now or would I be asking for trouble?

You can assemble it now if you like. Coat all machined surfaces with a good coat of oil or grease before you put the bag over it. If you install the heads, it would be best to leave the rockers loose so some of the valve springs aren't compressed.

I have the block ,rotating assembly and harmonic damper. The kit cam with SRP full floating pistons/ARP rod bolts. I'm still waiting on the flywheel so I can get it balanced and the cam from Summit.

I need to get the rod and main bearings now. Here is a link to some and was wanting to know if anyone has ever used them on a street car or is this a race only type bearing.

You need the rod bearings for balancing, but not the flywheel or damper (if the shop knows what they're doing). IF the damper and flywheel are attached for the balancing job, insist that they not be modified as part of the balancing.

I would use a regular oil pump over the hi volume one.

I had to put the build on hold because work took a nosedive. I've since changed jobs and the main reason was for the money so I could get this car rebuilt.

I have a price quote from ARP on a set of 195 comp heads with a max lift of .650, 7/16 stud and Ti retainers. The xfi 292 cam is spec'ed with 1.6 rockers. If i go with a set of 1.75 ratio which brings the max lift to .640 should I see a bigger gain or would this be asking for trouble at high RPMs.

I'm getting a TPiS miniram and have Applied Nitrous Technology install a fogger system.

I'm trying to squeeze as much as I can to get the max horsepower I can at the dragstrip. The car has to pass a visual test on emissions. It will not be a daily driver but will be driven and hard. My main concern is at the track.

For the last year I've done a lot more research and have a better idea on what I'm wanting now.
