Hi. Anyone on speedtalk also on The 47 to present chevy truck forum? I joined as i own a 63 c10. So aiming for the 60-66 section. I joined on the 24th of january, my account was activated but needs to be added to the forum by a moderator, basically 5 weeks now and nothing happened as yet. It is frus...

Check jeep 4.0 pistons. ( 3.935 bore) Comp height is 1.353, on 350 crank rods will be at 5.9". From memory, did look at it a long time ago.
Chevy 250 inline 6 pistons is a tad lower on comp height, but works with the 307 crank. Still gonna be a 307.

Not all 283s can take bigger 327 crank.

What is left on wall thickness?

Know that all to well. Some kits are worse than others.
Got some old stock i keep to use when really needed.

194 used rope type seals. Over the years the rope wears the crank and there is a wide-ish groove, so rope eliminator seals is not gonna seal properly. I have a 230 and a 250 crank with the same issue, here the rope seal was used almost to the end of production run. Easiest solution is to use a rope ...

CF, they were the o-ring type installed by machine shop. I am unsure of the size. Reason i'm asking is it could be the cause of the oil in the intake. One of those cases of ask me how i know :lol: Many shops gets the correct way of assembly wrong. Look inside the spring, if the seals is on the stem...

I know it was mentioned valves and seats being done.
What type valve stem seals?

I must apologize and correct myself.
Sorry for (my) the confusion. The 265 sbc pistons actually matches the 215 inline six that pontiac used. The 194 has a smaller bore, only same comp height.

The 194 inline 6 uses same pistons as the 265 v8 from 50s. Pistons is hard to get. Next size up is the 215 that was used by pontiac but bore is to big to go from the 194 to 215. 194 had rope type rear main seal, here in south africa our chevy inlines used rope seals up until the 1980s, 230s and the ...

No expert on carter carbs. Sounds alot like fuel pressure is overcoming needle and seat. Or float chamber vent to atmoaphere blocked.
I could be wrong.

I have a 4-71 that came off a detroit.
Changed seals and went sealed bearings after the clean up.
And convert the front gear cover for oil containment for gears. Got some gilmer pulleys to use.
Still need to make a snout setup as i want to use it on a 250 chevy inline 6.

Chevyfreak.

My initial thought was that they were from a compressor. Would that follow from your Detroit 4-53 assesment? From the blackness on the rotors i would say on a diesel unit, and some oil leaking past the seals. And the color as well. The detroit v motors used those colors and with the double ribs. Ch...

Looks alot like a 4v53 detroit.

Edit.
Upon checking google quickly it could also be 6v53 or a 8v92.

Ø" x Ø" x .7854 x Stroke" = cyl displacement in " Ømm x Ømm x 12.87 x Stroke mm = cyl displacement in cc I use basically the same one but little different in placing. The one i learned is. Bore x bore x stroke x cyl x 0.8754. = total displacement. Formula stays the same for ci o...

Making the competition waste time, money, effort, and enthusiasm trying to reverse-engineer the thing, when they'd be better-off dealing with their own combination rather than monkey-see-monkey-do with your stuff. I'm not in competition with anyone, nor challenged anyone on this forum. I asked a qu...
