Took the 500 to the machine shop today

I decided it was time to get the ball rollin'.
I wanted to go with the KB pistons but with the 76cc heads, the motor would have been at 10:1......a little more than I wanted. The shop has a set of "552" heads which are 120cc heads. Those heads and a set of KB pistons should put my compression at around 9:1. I like the sound of that a lot more.
It'll be, pretty much, a stock build with exception of the pistons and the MTS MT-10 cam (which I ordered today).
Puts me one step closer to making lotsa noise and thick white tire smoke.

Get bigger intake valves and inexpensive bowl work and it will be the best performance mod you make. Except maybe rear gears better than the cam and intake which are good mods.

"Extra" head work isn't in the budget right now.....maybe in a year or so.
I talked to Al and told him what I was going to be doing with the truck and that is what he recommended. We'll see how it runs when I get it back and in the truck.

Update:
It's been a while since I posted any info on the build......thought I'd give y'all the latest.

A few things have changed in the 500 build.

First.....there was a mix-up with my cam. They sent the VT10 instead of the MT10 I ordered. Al (at MTS) offered to fix the problem and send the correct cam out the next day. I asked him what the difference was between the two. He told me and I decided to keep the VT10. The VT10 is an Erson cam and the MT10 is a Comp cam. The MT10 has a high lift, short duration. The VT10 has a longer duration and less lift. He said they both do the same thing, they just have different ways of doing it.

The block was bored .060 over and decked (not sure how much) and the crank ground .010.

I had them tap the oil galleys at both ends of the block and also in the lifter valley for threaded plugs (per the "Big Inch" book).

The block was drilled and tapped (just under the thermostat) for a heater hose fitting. Now I don't have to worry about clearance issues with the original fitting at the rear of the right head.

I went to the machine shop today. The short block is finished. Now they have to do the heads.

I DID decide to have a little porting done and bigger valves installed. I figured the cost will be minimal concidering what the total build was going to cost.

Friday I ordered the shaft rocker set-up, Edelbrock intake, Pertronix distributor conversion/coil, MSD 8.5mm plug wires and a few other odds and ends.

That's where it stands now. Hopefully I'll have it back in the next few weeks (the machine shop doesn't work very fast ).

I seen that. Nice motor but a little too radical for me. That's pretty much and all out race motor. It would be fun to play with though.

Are you taking pictures along the way? I'd also be really curious to know about how much money the rebuild cost you, if you don't mind adding it up. I know that hurts a bit sometimes!

Thanks for the updates! Looking forward to you getting it in your truck!

I didn't even think about getting pictures of the build until yesterday. When I got to the machine shop, I found that the short block was already done. He's been taking his sweet time getting everything done but he gets busy when I decide I want pictures. Oh well......I should have thought of it sooner.
I've gotta go back to take them the shaft rockers when they come in. I'll take my camera with me and get some pics.
As for the cost......I'll let you know when it's all done. Just in the bottom end (not including the drilling and tapping) I've got almost $2200.

I got a few pictures of the short block today. The picture of the top of the motor didn't turn out to well. The motor was on a stand and I didn't want to try to turn it over so I just stuck the camera under the motor to take the pic.
Nothing has been done to the heads......so I didn't take any pictures of them.

So what valve size are you going with for your lower compression engine ?

To be honest......I don't know the exact size. Bigger than stock is all I know.
I'll have to ask the next time I talk to him.
How big are the stock valves?
