$50 Craigslist 360 EXTREME budget rebuild??

-
Okay had a little fun out in the garage today got the new main seal in got the windage tray bolts in retorqued everything. Put windage tray on. Oil pump on. Cam back in and then cap over top of that. Put all the freeze plugs that can fix up the two in the back that I can't get that with the motor stand in the way. I want to do some more cleaning back there anyways after the oil pans on. Wife was helping me most the time. She put the assembly lube on the cam and put it in. And as always did a lot of cleaning and pretty familiar with the torque wrench by the time we were done. That she bought me for Christmas? Hey wait a minute!

Was helping others with their car projects today and only was able to install and line up timing chain and gears. We also torqued on the fuel pump cam. The double roller wasn't tight, as a matter of fact it seems loose.. oh well.
oh yeah, friend gave us a Edelbrock proformer 318/360 intake! I don't know though? That 340 cast iron intake look like it had a lot bigger runners in it, As I remember? It was a hell of a lot heavier also.

Does have bigger runners, and it is heavier

Do I need the bigger runners though ?

intake gaskets are cheap! Try them both! I have :)
 
The kit came with 2 intake gasket sets. One set is metal and looks like ether for magnum or stock iron to iron?
 
Since you don't have your heads bolted down yet, I wouldn't get too worried about intake gaskets; the choice is use the one that fits/works........start with a no gasket mock up, see where bolt holes line up, go from there...........
 
So I'm looking at these .030 over pistons and I started thinking (i known) these don't look far enough in the hole? So I break out my silly-puddy and a strait edge. Squished the puddy and measured .010 ? And .050 off the 360 heads. Hopefully I'll be in 8:1 territory ?

I though the metal was for 318 and the fiber was for 340/360. With your heads shaved the metal may be more appealing....... holed them together and see if the opening is 318 or 340/360
 
I do now.that you say that remember the metal one having smaller holes for the runners

The 318 right? I got lost in this thread a while back LOL...

Do you mean that the pistons are .010" or .100" down in the hole? The .100" would make more sense. 318's never had pistons .010" down in the hole from the factory. They did have some low compression truck pistons that were around .100" down in the hole; othes were around .080" down in the hole.

A .050" cut on the heads would run the chamber size down into the low 60 cc range; I'll guess 62 cc's . That, with a standard Felrpo .051" thick head gasket and -.010" piston-to-deck height, would put the motor around 9.6 SCR. The same head and gasket with a -.100" piston-to-deck height would be around 8.0 SCR.

So are the pistons .100" or .010" below deck? 'Inquiring minds want to know' and all that....

BTW these .050" shaved 360 heads will have SMALLER chambers than unmilled 318 heads of the day, such as the 675 heads. Those are typically around 68 cc's and your chambers are now in the low 60 cc range. With the thick Felpro head gaskets you are ending out around dead even on compression ratio vs the stock 318. As 318willrun has been saying....

If you have $50 dollars, I'd put in the MrGasket 1121G head gaskets and pick up around 4 tenths of a point of compression. Is this just for drag racing or some on the street too?
 
.010 according to my cheap Harbor Freight digital micrometer. Don't be surprised if I can't read a mmicrometer. Yes it is the 318, I tried to Edit the first post to skip people up about a hundred and fifty post or so but it won't let me and my efforts staff were unfruitful to the best of my knowledge. I'm not even willing to read back through all that to check. LOL
This was a rebuilt 318 and I believe the guy was looking for performance? they're 30 over pistons and they may be some kind of extra custom height or something? It's got an upgraded cam of course which I'm going to go ahead and reuse. It looked good and I got thirty thousand lift? 1.27 to 1.57 ?

OK on the .100". These must be those "high performance, low compression" 318 truck pistons I have heard about but never seen....marketing can do anything, LOL. Head gaskets young man...

The 'where do I set cam timing' for this engine will be interesting. To start building the drama for that part of the thread: how is this engine going be used? Pure drag race, going to the grocery store, or what?
 
$$$ budget build. I can't. Oh yeah. If I use the aluminum intake that was given to me I can deduct the $50 I spent on the cast iron. Putting the total from $350 to 300.

Use the OE intake with a TQ and it will be awesome. I think the factory intake is better than the Edelbrock. The weight is a nonissue.
 
First- WHERE THE HELL HAVE YOU BEEN ??
Second I'd like to run the stock manifold and the thermoquad. But I'm not looking forward to an education on thermoquad (as stated before my education's always seem to cost me money) and yes there is a major major weight difference between the two manifold I can tell the runners are the same with but the stock manifold has taller runners.

Sick as a dog. I'm finally feeling better and last night my mother in law had a stroke.

As far as the TQ, if you can tune an Edelbrock or AFB, the TQ is conceptually the same. It should be a short learning curve on the TQ and they work very well.
 
And the TQ needs tuning why????? J par, you haven't even tried it and you have the horse dead. It very well could be a bolt and go.....
Just say'n
 
For now- just getting the motor to painting stage would be great. Love to run the tq. I've got a hole new system going in the car - a LOT of $50 Craigslist budget rebuild stuff. Just trying to eliminate potential problems. It would be nice to get it all together and running with a known carb and then try an unknown thermoquad? I wouldn't mind taking a chance on a manifold that's been sitting in the back of a trailer in a storage unit,but it's the whole carburetor that's been sitting in the trailer in the back of the storage unit for an Untold amount of years that I'm concerned about and looks all black and burnout? I'm not only worried about this $50 Craigslist motor that have now put $300 into starting, but the free transmission going in to gear or the swap meet shifter putting the transmission into gear LOL just trying to eliminate potential problems it's all in my mind probably
