Re: 1983 Chevy lwb slow build
 

Few new updates:

going to start building the motor when it comes out of the machine shop. Here are the specs that are gonna be on the engine:

400 Small Block bored .030 over destroked to a 377,
Steel 3.48" stroke crank,
Forged I-Beam 5.7" rods,
Dish top speed pro pistons,
comp xtreme energy 268H hydraulic flat tappet cam(we had to change the cam, the one that the guy gave us was WAY to big),
stock 400 heads that are reworked(or possibly some aftermarket heads if we can find some cheap ones),
Holley Street Dominator Dual Plane Intake Manifold,
Holley Street Avenger 670 cfm Carburetor.

I'll upload some pics of the new parts I have bought whenever I can.

Re: 1983 Chevy lwb slow build
 

I guess I can also show some videos of the Truck.

Here's one of what it sounds like after I first got it:


Here's one with flowmasters and a new cam:

Re: 1983 Chevy lwb slow build
 

I love that sound...makes me wanna yank tha 350 out tha camaro & drop it in tha tha truck..

Re: 1983 Chevy lwb slow build
 

Thanks, I can't wait to hear how the new engine is gonna sound :)

Re: 1983 Chevy lwb slow build
 

Here's a random picture I took from the back of the truck, then the gaskets, new cam&lifters, and holley street dominator intake. I'll take a picture of the Carburetor when I can, it's on my 350 that's in the truck right now though.

Got the block back from the Machine shop!

Re: 1983 Chevy lwb slow build
 

Got the block on the engine stand today and ready to get workin so we started putting in the Bearing spacers and Main Bearings and then noticed that we have the wrong Main Bearings. We have the bearings for a 400 and need the bearings for a 350, so that's about as far as we got today; was hoping to get the crank put in today but that didn't happen.

Re: 1983 Chevy lwb slow build
 

More pictures coming soon, got the new correct Main Bearings and the Crankshaft is now in the engine. Sunday we will be putting the pistons/rods in.

Re: 1983 Chevy lwb slow build
 

3 freeze plugs..4 bolts...ahh..what a gem..

Re: 1983 Chevy lwb slow build
 

Is it bad to have 3 freeze plugs on a 4 bolt main?

Re: 1983 Chevy lwb slow build
 

There's no problem with only the 3 freeze plugs, heck some new cars don't come with any. Freeze plugs are just a fail safe for when people stop properly maintaining their coolant.

That block came out really clean and nice from the machine shop. How much more HP do you figure that the stroker will produce over the built 350 in the truck?

Re: 1983 Chevy lwb slow build
 

I'm thinking it'll produce MUCH MORE HP, because the 350 in there now is old and tired. I'm hoping it'll be at least 100+ more hp, although I'm not sure how much the 350 in there now has.

Re: 1983 Chevy lwb slow build
 

Put more of the motor together yesterday. Got the pistons in, put the cam and lifters in, and put the timing chain on.

Re: 1983 Chevy lwb slow build
 

Also put the heads on, they are reworked stock 400, 493 casting number heads. 1.94 intake/1.50 exhaust I believe.

Also, the guy who reworked the heads said he put z/28 springs on there. Anybody know what that means?

Re: 1983 Chevy lwb slow build
 

Will be installing rocker arms/pushrods tonight, then we will set the valves.

Re: 1983 Chevy lwb slow build
 

Hot damn! That motors coming along nicely!

Re: 1983 Chevy lwb slow build
 

z28 springs are just stronger valve springs to go along with the higher lift on the new cam so you dont get any valve float. I think they must have been a popular spring that came standard with z28 camaros back in the day. the motor looks good by the way, are you gonna paint it chevy orange or do you have something a bit more custom in mind?

Re: 1983 Chevy lwb slow build
 

It's gonna be painted blue, kinda to match the truck. Was hoping to paint it today, but didn't get to it. Got the rocker arms/pushrods on though!

Re: 1983 Chevy lwb slow build
 

Blue... anything but blue...:chevy:

Re: 1983 Chevy lwb slow build
 

You know most people dont like blue motors in a chev, but i think if its done right they look amazing. its something you dont see every day.

Re: 1983 Chevy lwb slow build
 

Yeah, the motor I have in there now is Blue and I think it looks good so I will probably just go the same way.

Re: 1983 Chevy lwb slow build
 

Paint is on! Also put the intake on there just to see how it would look. Would have done the same with the valve covers and carb but they are on the engine in my truck.

Re: 1983 Chevy lwb slow build
 

Can't see the last photo very well... lemme try again...

Re: 1983 Chevy lwb slow build
