.010 probably would be good enough, but since the cost is the same at the machinist, and the pistons and rings cost the same, .010 might as well be .030.

Foe,

I found my complete 331 kit for $450. Guy was in a jam and needed money. Look around in your local ads and online and I bet you can find either a 331 or 347 that is in your wallet range. There is no replacement for cubic displacement except if your going to compress the air going into a small motor. Just a thought if you are gonna lay out some hard earned $$$.

I would, but I seem to remember getting irate with another member here about whether or not you could make 425 N/A horsepower with a 302 inch Windsor motor that culminated in my responding with "Challenge Accepted". Don't remember who it was, and it WAS about 2 years ago, but a challenge is a challenge.

i dont remember that debate,, so are you going to build your car the way you want it this time? with a target of 400+hp with mild bore?

Actually, I got a really good look with the slugs out, and I'm not going to bore. I may if the machine shop tells me I have problems, but barring that, I'm going to stay at 4.000. I'm getting a tfs stage 1, 1.7:1 rollers, GT40Y heads (which I will port), -14.7cc KB domed pistons and 36# injectors. Compression ratio should be about 10.8:1. I should be in the neighborhood of 385 at the crank. The only thing I'm really worried about is valve clearance, but that's what the clay is going to be for. Otherwise, all the usual refinements, Melling, ARP everything, Clevite H series, etc.

VHT Flame Proof. I got some VHT Nu-Cast aluminum I'm going to use for the aluminum parts, too. Just something to help pass the time while I'm saving for the first batch of machine shop work.

I would not mess around and punch that puppy .030 and build a 347 and call it a day. In all the years i have been building engines i never punched a block .010. They normally never clean up at 10. And you have to worry about taper. Busted scirts are common on HYPER PISTONS They are JUNK for a performance build. The only engines i punch .010 is LS motors as they are sleeved and that is the limit. If 10 does not clean it up the block is sped. Leson learned never build an engine with Hyper pistons and always punch out the block. This is the only way to stack the cards in your favor.

The cylinders are clean, so if the machine shop doesn't tell me they need to bore (which they may), I'm not going to bore. If they tell me I need to bore, it's at least .030. Like I said, 10 might as well be 30 seeing as how it costs the same. Hopefully, I'll be able to get the block to them next week. Once they've seen the block, I'll know what size pistons I'm ordering.

i wish vht ~flame proof~ line up had chrome,, all our flame proof color vht paints are holding up very well, you will be happy.

Mega Update.

Where's the MAF?

But WAIT! There's MORE!

Obviously, 30 lb/hr injectors don't play nice with un-tuned speed density EFI, If you'd been in the shop for the first start, I wouldn't have to tell you this, you'd still be choking on raw fuel smoke. FiveOlogy to the rescue. Stage 2 MAF conversion including sensor harness, reman A9P, extruded aluminum elbow, silicone couplers, and a 73mm MAF housing calibrated for 30 lb/hr injectors (and bearing a genuine OEM Ford sensor). The housing is similar in design to a C&L meter with swapable sampling tubes that I hope I never have to mess with.

Not the best fitting piece in the box.

Broke the camera after this pic so you can't see the nice clean finished packaging.

Still running rough, So I got out the cylinder balance tester and found #4 and #7 dead. Noid lights, injector tester, fuel pressure gauge, and compression test, show that I have a rocker preload problem that has to be corrected with shims. Basically, on the first crank cycle with the engine cold, compression is great, but 2 or 3 cycles into cranking, oil pressure comes up forcing one or more valves to not fully close on the compression stroke. Somebody may have warned me about milling and decking and rocker preload at one point, but the whole build took so long I just can't remember. $10 shipped for FRPP shim kit, so we'll see if they show up from CPS tomorrow or Monday. This thing had better knock my socks off once it's running right, I'm getting sick of buying stuff.

Yeah with milling you're going to need shims. You'll have to check each cylinder to make sure it's got the proper pre-load. My block had been slightly decked when it was rebuilt to clean it up. When I swapped on the Edelbrock heads I had to use one thick shim under each rocker to get the proper pre-load. Oddly enough the rockers were fine with no shims when the car had GT40P heads.
