Very nice looking. Can you give us a few more details on your build please? I know I've read about some of them, my memory is a bit fuzzy at the moment.
Why do they have a full dish instead of a D-shaped dish or if you want to call it, an inverted dome? A full dished piston doesn't have a quench pad, the new TA heads are supposed to be closed chamber. If you go with the new closed chambered heads with a full dished piston that would cancel out them being closed chambers. Or are you going to setup for boost?
Is the shop building your engine or are having some thing done by the shop to your pistons? If so what? Thanks
I'll try and remember everything, its been a year so far LOL Stock crank, Molnar rods, forged pistons (11 to 1) with 1/16 rings My original '71 block .040 over Head and main studs Oil mods TA hydraulic roller cam, TA 1.6 roller rockers TA timing cover MSD 6A SP3 with 850 AED DP Robb Mc fuel pump.... They put a 350 pump arm on their 455 pump 1/2" Robb Mc pick up and 1/2" line HEADS........ I'm HOPING for the TA aluminums by spring, but I'm going to have my irons gone thru, they already have the TA big valves and some porting/bowl work, they were done 100 years ago LOL Everything listed I've been running for years except the rods and pistons I'm REALLY on the fence about putting the irons on for now, especially putting money into them to have them gone thru, when that money could go towards the TA's, BUT, I wanna drive the car Transmission has been rebuilt by Vince Janice with all the good stuff including the 34 element sprag assy. AAAAAND my AWESOME JW 9.5" convertor! There are other small things I'm not remembering now, I'll update as my build goes along.
No boost Derek, NA for me The biggest concern I have is I wanted 11 to 1 for the TA heads, but I feel I'm going to be running my irons for awhile if the TA heads don't surface by early spring.
I'm doing the assembly. The pistons are going in/on as is. I am having the rotating assy. balanced tho
You should check what your current bobweight card says and see how close the new components weigh out, for curiosity's sake. Compare the difference into the formula and see what % change it is.
What compression were you running before? The new heads are on my list too, but I'm not going to run them on the 350 I'm working on now. I have another block sitting here (thanks Briz) that will hopefully be a twin turbo build.
Those are the AtuoTec pistons that I have posted a link for you 3 or 10 times and mentioned about another 5 or 15 times in other threads you were in the discussion with.
I'm not sure on compression on my last build, the pistons were .005 in the hole, and were suppose to be 9.25 to 1 @ .020
No one makes 1 set of custom cast pistons unless its for someone with more dollars than sense, come on Jim, you know better than that. If you ever opened the link I have posted many many times in the past you would know what the AutoTec pistons are. Google can be your friend if you really need to know.GL
