shortblock finally going together

[KendallF]

OK, I'm going to try this attachment feature. Here are a couple of pics of my shortblock, finally being assembled. I did something a little bit different with the BRC pistons and had them made with a D-shaped dish to try and make the chamber a bit more efficient. It's an early on center 4.1 block, 4.050" by 3.632", 280ci, with a Motorsports crank, Carrillo rods, and the BRC pistons.

Kendall,

That is great, makes me want to finish my stage motor.
How much power are you shooting for???

As much as it'll make without kitty litter... :p My first hope is that it just starts up and runs with no issues; I have a lot of custom stuff here and I have done every speck of the work. When it shakes down, I would like to see 1k out of it.

Looks great Kendall. Those headers sitting on the floor look nice too. You shooting for the Nats or what????

I am going to race your golf cart with it.. :fly:

I bet mine will do a longer wheel stand :rock:

What ring arrangement are you using on those unique pistons? Floating pins?And what about the heads? You must know the cc to have given a displacement. Which head gaskets? Compression ratio? Valve sizes? Cam and lift? How much clearance from valve to top of piston? There are so many questions, I will try to be patient and just wait as you put things together.
I admire you mechanical abilities.
Nice photography too!

Thanks for the good words. :) There are a lot of details on my car and engine at my web site (in my signature). I haven't updated it recently as I need some more space.. :cool:

The rings are 1/16, 1/16, 3/16 conventionally gapped Sealed Power with a moly top, cast 2nd. Top gap is .026", 2nd is .022". The pins are floating with Spirolox retainers. The S2 heads are shown on my web site along with some details on the machine work done on them; they have 54 cc chambers. Head gaskets are Cometic .040" thick, 4.090" bore. CR checks in at 8.66:1. The valves are 2.125 and 1.60 Ferreas, cam is a solid roller with 248 duration @.050 and .650" lift. The pistons are .010" in the hole and I haven't gotten the heads on yet to check valve to piston clearance. Whew..I think that answers everything... :dong:

Kendall,

Looks great!

Nice reverse dome pistons there Kendall. Weisco screwed mine up. Dont think they know what reverse dome means.

Today was my 13th wedding anniversary...so I worked on the motor. :) :marchmell Actually, I took Jenn out for breakfast and for a nice evening out, but in between, I got some work done.

I made a brace for my oil pickup; thanks to a tip from Lee Thompson. I replaced one main stud with a windage tray stud meant for a BBC. This makes a great attachment point for a sheet metal brace that's welded to the pickup tube.

After taking those nice pics above, I got the timing chain on and got ready to degree the cam. Turn the motor over...bump. :stupid: :banghead: Some (not all) of these rods had been previously clearanced for the cam, and they had one rod bolt ground to clear as well. I'd carefully assembled them with the ground bolts on the cam side..but on two, I'd swapped bolts side-to-side during resizing. The non-clearanced side of the rod was next to the cam.

%$#@^%~! I had to pull #2 and 6, pull the rings, remove the Spirolox (more cussing), swap the pistons around, go dig up more Spirolox, and reinstall the whole mess. Fortunately, that went pretty quickly and it now rotates all the way around, and the cam degreed in just fine. :) :anbet: You can see the rev kit style Isky lifters with one of the rev kit springs in place.

Hey Kendall.....hope this is worth all your time an effort :arco: I am waiting for headers still . If something doesnt happen soon I might bail an move on to a new car :D
