A friend is having a motor built. He was sent these "progress" pictures of "his" motor. When I looked at the dates, they were all taken early in 2002! - Unless the date on this guys camera is off, and it might be.

What I would like to know is - was the hardware in these pics even available in 2002? This is supposed to be a Dart blocked 331. Here is the description too - please let me know if this adds up.

DART Iron Eagle 8.2” deck
331ci short block assembly INTERNAL or “0” BALANCED
4.03" bore, 3.25" stroke Eagle Internal Balance 4340 crank
5.4" Eagle 4340 H-beam rod ARP 2000 rod bolt upgrade
Probe SRS pistons 14.2cc dish
plasma moly ring set
Clevite H-series Main and Rod bearings.

Canton 7qt Pan kit
Melling HP Oil Pump
FMS oil pump drive shaft
ARP stainless Steel bolts
ARP oil pump bolts
Rollmaster Billet Timing Chain
FMS Billet Steel retainer plate

Thanks guys

 

my biggest question would be the piston, not too many companys are still making pistons with the oil ring intersecting the piston pin, that was the biggest problem with strokers is the oil consumption. The biggest deal, was oil blowing pass the oil ring. I thought most places stopped selling those pistons a cople years back.

 

yea, but I thought that was only a 347 issue not a 331?

Date on the camera is likely wrong....why doesn't your friend just ask the engine builder?

 

It was the 347. And plus 1 on the date being wrong

 

He's been waiting for the engine for a while - that's why I am "inspecting" these pictures. Doesn't the crank look different in each pic? Check out the front counterweight (note - block is 180 different in each picture). In one pic, it looks kinda smoothed/polished - in the other it looks as-forged.

So, you are saying that if the engine builder sent him that picture of a rod and piston and told him it was his, for his 331, then thats BS?..being that the ring config pictured is likely an old 347 setup?

 

first pic has freeze plugs in, and painted, 2nd they are out?
im also calling bullshit on that being the same crank. the first is counter-balance drilled.
also, the first is painted black and the second isnt the same.

jeez, how far away is the builder? just ask him to send pics of HIS block next time.

BTW Jeff, any progress pics of the fastback?

 

Whats the difference between the 331 and the 347 piston???

Its the same damn piston with a .030 overbore. But again I dont think anyone makes pistons like that anymore. :EDIT: I looked in my Mahle and Diamond and JE/SRP catalog,there claim, to not have the oil ring intesect the piston pin.

Nevertheless, Dart blocks for Ford existed in 2001. Thats when I bought my first Dart block.

But those are two different pics of engines nevertheless. One is painted in Satin, the other is in gloss. And yeah, shineysideup is correct one is counterbalanced and the other isnt. Definetly two different engines though.

 

Negative. 331 is 3.25 stroke and the 347 is 3.40

 

Damn, lets try this again, Um, yes I know this already, thats the crank bro. The 331 assembly is a 4.030 piston with a 3.25 throw on the crank, the 347 is a 3.4 throw on the crank, which still uses a 4.030 piston on both setups, which I already knew, and tried to explain.

Nevertheless, two different blocks......

:Edit: We dont need to go into rod lengths as well do we??? 5.400 or 5.090... maybe we should discuss piston pin diameter, or maybe crank radiui, either ford standard or chevy/honda possibly?
