I would start with 10 psi but with forged pistons and a low compression ratio and intercooler I see no reason not to go to 15 psi if you need the extra torque.

About $600 for a set of those right?

I haven't checked this year but the last price was less than $550 for a set of 4032 alloy forged pistons and pins from Autotec.
The pistons using the Ford .975" pin cost $40 extra.

What connecting rods do you plan to use?

I might use stock, maybe custom. All depends on my full time pay check.
I remeber seeing a set of nice rods on another build that was the same width all the way down. But i assume they were out of my price range

Nearly done. Just gotta drill and tap holes for studs and fittings and powder coat it. My measurments i got must have been for the hole spacing of the 2100 because my mounts were a little big, but it still looks good to me ans ought to work just fine

Did you do the 4 threaded holes for the 1/8" fittings?

Thats one if the things i need to do. This is my last week of school and i wouldnt be able to get the fittings and tap till next week. So ill just drill the holes with a vaccum by the bit to collect any shavings. Then the whole thing is gonna get a wash before its powder coated too

Is there a spot at least 1/4" thick for enough threads to support the fittings?

yes, on the very back I stacked a 1/4" plate on top of the 1/8" sheet aluminium and welded it on

Well I got a new phone, drove around a couple hours looking for the old one and no luck. This new one takes much better pics though :thumbup:

I got my engine block back yesterday. And my intake painted too.

P.s. check out my other thread in mustang corral about possibly buying this 65 mustang

If I might ask what is your L - W - H for your plenum?

Are you planing to run two 2100 Autolite carbs?

I don't remember exactly but I believe I went slightly over 4 inches on the top 3.5 on long side, 2.5 on short side and 4 on the bottom.

Also I have my one carb mounted up on two studs I ended up having to make from 3/8 "all thread". Meaning I also had to drill out the holes on the carb slightly too.
Pretty tight clearances but the carb fits on there

Update: I graduated basic training. Now I'm going to AIT (Advanced Individual Training) to learn how to work on the Bradley fighting vehicle. I should have some phone privileges a little more so I can order parts. My budget has significantly gone up, I'm not too worried about price now, but still want to keep it reasonable.

To restate where I was in the build, I got the block bored .030 over and finished my intake manifold. Still need a head (plus the machine work and parts for it, pistons, connecting rods, and a cam.
Anyone have an 85 model head they would part with?
