iām not up on yank v8ās but big block?  Possibly, looks Ford to me with the distributor at the front tho its a Australia Ford Cleveland , Hence the blue, (what's left of it) block but red valve covers, out of an old Falcon XE, and HD C4 auto box, same engine as was supplied to De Tomaso for the Pantera's I was told but who knows? I have been working on the truck in the background and that Bentley lump has been really doing my head in ! not quite running right and cant seem to sort it out, plus everything is pretty pricey for it , so bit the bullet and brought this to freshen up and stick in for now, it came out of a running car all be it a while ago, 2v heads, 4 barrel carb etc , and it only needs a couple of wires to get it running unlike the Bentley, I will give the Bentley just one more chance the weekend to play ball, but its coming out anyway to do the head gaskets etc and I will build a Jig/trolley so I can run it out of the truck and sort all the little niggles and either put it back in or stick it in something else. I want to use the truck this summer after 2 years of building and the engine is stopping me at the moment, the rest is pretty much there now, and I'm more at home with a carb and stuff then ECU's and bosch CIS, # BuT i wont let it beat me just yet.. even if it ends up in something else |

Excellent, this should be running and driving by the weekend then!
So is it a 351 motor? or a 302 if its paired to a C4 box?
I've got a 351W in my F150 and that's had a blower on it for years and seems to be holding up ok (touch wood) haha

(its a different block to my 302 Windsor) higher compression than the US engines etc I need to do some more reading about them really |

Pantera used a 5 speed zf box.
The heads on those Aussie Clevelands are closed chamber with the 2v ports. They were quite desirable in the 80's and 90's (before aftermarket heads appeared) as they gave good compression and quench on 351C's without the low speed flow of the 4v heads (and 4v closed chamber heads are rare). The 302 rods are long and spindly but a 351 crank and rods go in.
My 351C had forged flat top pistons with the 302 heads (ported) which gave 11.5 to 1 comp ratio. Ran high 11s in a pop and was driven everywhere.

A 351 rotating assembly will go into an Oz 302 block (because it's the 351 block). The 302 used a shorter stroke and long rods to get the piston's back up to the top of the block. If you do have the quench heads I wouldn't recommend it due to the high compression ratio it gives (mine was in the 80s when good fuel was still around). |

Well that is a properly interesting engine, had no idea about them!

been stripping the engine to check it over and give it a refresh after work   turns out it has got closed chamber heads and someone has been in there before and put new pistons in , need to take my bore gauge home and check if its been bored to tonight as a rulers wasn't the best for measuring |

It all in bits now , only found 1 cracked ring and bearings all look ok ,but will order up new rings and a full set of bearings this week and give the block a good clean and a hone and some paint ready to start the rebuild, also ordered a Eldebrock manifold and a double pumper Holley 650cfm carb as not sure how the old thermo quad will like the e5-e10 fuel we have now as it has a resin middle section , if anyone has one let me know how they hold up,  also designed and printed this a couple of weeks ago and totally forgot about it , been a lot of stuff going on lately, fits well and works ok , its should work ok with the C4 as that/s a 3 speed to .  |

It's great what can be made with 3D printers now.
Double pumper? Vac secondaries might be better?

Vac secondaries might be better? brought a Holley Street Avenger with electric choke and vacuum secondaries went with a 670cfm to keep the torque hopefully , but i did loads of reading and the internet has lots of opinions on what carb you need lol |

Enginemasters did a dyno test between two Holley carbs (both same CFM), one double pumper & one vac secondary.
It was quite interesting on the results - the double pumper had about 8 more horsepower at high RPM.
Both had same jets & venturi sizes so they were baffled at first.
They finally worked it out that the reason was the double pumper has the extra squirters on the secondaries which at high rpm the vacuum past them sucked extra fuel into the engine.
Overall though the Vac secondary was better as a street carb.

Sounds like I made a alright choice then carb wise, been cracking on with cleaning and going through the block and bits   We have a Formula Student workshop next our machine shop in work, which is handy as I got them a Hot wash parts tank a few years ago, pistons and rods came out pretty good with a clean and then slung them in a ultrasonic as some of the top rings were stuck in there, this managed to vibrate and clean out the curse word in the ring gap so I could get them out, they came up prtty good , gotta sneak the crank in next week and clean that to and brush out all the oil gallery's to , my mate in the workshop next door has just brought this to, we went for a pint the other night when the sun was out to the local.  it's not helping my wanting for a '20-30's Ford one bit !! but I need to finish the other 2 trucks first..... this turned up in the post from the USA to  A C4 yoke, but with a flange to mate up to the prop shaft I already had made for the TH400 , which should hopefully just bolt up , but we will see. and been welding this Mustang 2 front clip I had laser cut the other week up in between teaching in work ready for the F1 I Have been gathering parts for it but been telling myself I have to get the COE moving first to get to the Weekender  |

One piston didn't want to play the game, even after multiple acid rust remover and ultrasonic baths , top ring still stuck as ten , now had to order a new set from oz  Block has been all cleaned and honed though and painted all faces clean and stuff   and made a rear light bar grille thing to  |

Looking absolutely mega!
That motor has cleaned up lovely, shame about that last piston! There's always one!
Mustang II clip is looking smart.

The Bentley engine delete...     She's a big old lump ! have been looking into Holley Sniper EFI kits ,so could in theory take all the MOTRONIC Bosch stuff off and block the injector holes and ditch most of the other stuff like Idle control valve etc and maybe even go to coil packs and get rid of the dizzys to, just a thought for the F1, also would like a manual behind it, not sure if they even did a manual Rolls or Bentley though ? or if another GM box would fit? Anyways cleaned up the chassis I couldn't get to before so will give that a lick of black and get the engine and box together this week and in mocked up to work out mounts and stuff |
